+\cgalFigureBegin{Surface_reconstruction_points_3figintroduction,process.png} +From left to right: input point set; Delaunay triangulation of input; after simplification, with ghost edges in grey, relevant solid edges in green, discarded solid edges in red; final reconstruction. +\cgalFigureEnd + +The task addressed here is to reconstruct a shape from a noisy point set S in R^2, i.e. give a set of points in the plane, find a 0-1 simplex which best approximates the non-noise subset of S. The related task of simplifying a shape finds an approximation of the original shape using simpler curves. + +The algorithm presented here performs the reconstruction and simplification task jointly using a unifies ed framework based on optimal transports of measures. This new method provides benefits such as robustness to noise, preservation of sharp features and boundaries. An optimal transportation plan is an assignment of the input-points to vertices and edges of an output simplex such that the 2-Wasserstein distance is minimized. + +The algorithm can be summarized as: "Considering S as a measure mu consisting of Dirac masses, find a coarse simplicial complex T such that mu is well approximated by a linear combination of uniform measures on the edges and vertices of T." + +It performs a course to fine simplification of the output simplex. It starts by putting a bounding box around the input points S and computes the Delaunay Triangulation T_0 on S. T_0 is the first output simplex, which is made courser in subsequent iterations by repeated edge contractions. To chose the next edge, a contraction is simulated for each feasible edge, i.e., edges which neither introduce overlaps nor fold-overs in the triangulation. The next edge e for contraction is chosen according to the overall cost of the transportation plan T \ e. + +The transportation plan is approximated by assigning each input point temporarily to a closest simplex edge. The input point is then peramnetly assigned to the edge if and only if the corresponding transportation cost is less than the transportation cost for each of the two vertices of the edge. Otherwise it is assigned to the cheaper of the two vertices. + +This sequence of edge contraction and transportation plan update is repeated until the desired number of vertices, specified by the users has been reached. + +After that, edges which carry little mass can be filtered out. + + + + + + + + +can simplify any oriented 2-manifold surface, +with any number of connected components, with or without boundaries (border or holes) +and handles (arbitrary genus), using a method known as edge collapse. +Roughly speaking, the method consists of iteratively replacing an edge with a single vertex, +removing 2 triangles per collapse. + +Edges are collapsed according to a priority given by a user-supplied cost function, +and the coordinates of the replacing vertex are determined by another user-supplied +placement function. The algorithm terminates when a user-supplied stop predicate +is met, such as reaching the desired number of edges. + +The algorithm implemented here is generic in the sense that it does not require the surface mesh +to be of a particular type. Instead, it defines the concept of a `EdgeCollapsableSurfaceMesh`, +which presents the surface mesh as being a halfedge data structure, and any surface mesh that +is a model of that concept can be simplified. The concept is defined not in terms of a monolithic class, but in terms of a set +of functions and traits, making it easy to adapt any concrete surface mesh type, +even if it is not a halfedge data structure at all. +In particular, the concept definition follows the design of the + Boost Graph Library (Bgl) +\cgalCite{cgal:sll-bgl-02}. + +The design is policy-based +(http://en.wikipedia.org/wiki/Policy-based_design), +meaning that you can customize some aspects of the process by passing a set of +policy objects. Each policy object specifies a particular aspect of the algorithm, +such as how edges are selected and where the replacement vertex is placed. All policies have +a sensible default. +Furthermore, the API uses the so-called `named-parameters` technique which allows you +to pass only the relevant parameters, in any order, omitting those parameters whose +default is appropriate. + +\section Surface_mesh_simplificationOverview Overview of the Simplification Process + +The free function that implements the simplification algorithm takes not only the surface mesh +and the desired stop predicate but a number of additional parameters which control and +monitor the simplification process. This section briefly describes the process in order +to set the background for the discussion of the parameters to the algorithm. + +There are two slightly different "edge" collapse operations. One is known as +edge-collapse while the other is known as halfedge-collapse. +Given an edge `e` joining vertices `w` and `v`, the edge-collapse operation replaces +`e`,`w` and `v` for a new vertex `r`, while the halfedge-collapse operation +pulls `v` into `w`, dissapearing `e` and leaving `w` in place. +In both cases the operation removes the edge `e` along with the 2 triangles +adjacent to it. + +This package uses the halfedge-collapse operation, which is implemented by removing, +additionally, 1 vertex (`v`) and 2 edges, one per adjacent triangle. +It optionally moves the remaining vertex (`w`) into a new position, +called placement, in which case the net effect is the same as in +the edge-collapse operation. + +Naturally, the surface mesh that results from an edge collapse deviates from the initial +surface mesh by some amount, and since the goal of simplification is to reduce the number +of triangles while retaining the overall look of the surface mesh as much as possible, +it is necessary to measure such a deviation. Some methods attempt to measure the +total deviation from the initial surface mesh to the completely simplified surface mesh, +for example, by tracking an accumulated error while keeping a history of the simplification +changes. Other methods, like the one implemented in this package, attempt to measure only +the cost of each individual edge collapse (the local deviation introduced by +a single simplification step) and plan the entire process as a sequence of steps +of increasing cost. + +Global error tracking methods produce highly accurate simplifications but take up a lot +of additional space. Cost-driven methods, like the one in this package, produce slightly +less accurate simplifications but take up much less additional space, even none in some cases. + +The cost-driven method implemented in this package is mainly based on \cgalCite{cgal:lt-fmeps-98}, \cgalCite{cgal:lt-ems-99}, with contributions from \cgalCite{hddms-mo-93}, \cgalCite{gh-ssqem-97} +and \cgalCite{degn-tpec-98}. + +The algorithm proceeds in two stages. In the first stage, called collection stage, +an initial collapse cost is assigned to each and every edge in the surface mesh. +Then in the second stage, called collapsing stage, edges are +processed in order of increasing cost. Some processed edges are collapsed +while some are just discarded. Collapsed edges are replaced by a vertex and the collapse +cost of all the edges now incident on the replacement vertex is recalculated, affecting +the order of the remaining unprocessed edges. + +Not all edges selected for processing are collapsed. A processed edge can be discarded +right away, without being collapsed, if it does not satisfy certain topological +and geometric conditions. + +The algorithm presented in \cgalCite{gh-ssqem-97} contracts (collapses) arbitrary vertex pairs and not +only edges by considering certain vertex pairs as forming a pseudo-edge and proceeding to collapse +both edges and pseudo-edges in the same way as in \cgalCite{cgal:lt-fmeps-98}, \cgalCite{cgal:lt-ems-99} ( +which is the algorithm implemented here). However, contracting an arbitrary vertex-pair may result in a non-manifold surface mesh, but the current state of this package can only deal with manifold surface meshes, thus, it can only collapse edges. That is, this package cannot be used as a framework for vertex contraction. + +\section Surface_mesh_simplificationCost Cost Strategy + +The specific way in which the collapse cost and vertex placement is +calculated is called the cost strategy. The user can choose +different strategies in the form of policies and related parameters, +passed to the algorithm. + +The current version of the package provides a set of policies implementing +two strategies: the Lindstrom-Turk strategy, which is the default, and +a strategy consisting of an edge-length cost with an optional +midpoint placement (much faster but less accurate). + +\subsection SurfaceMeshSimplificationLindstromTurkStrategy Lindstrom-Turk Cost and Placement Strategy + +The main characteristic of the strategy presented in +\cgalCite{cgal:lt-fmeps-98}, \cgalCite{cgal:lt-ems-99} is that the simplified surface mesh +is not compared at each step with the original surface mesh (or the surface mesh +at a previous step) so there is no need to keep extra information, +such as the original surface mesh or a history of the local changes. Hence +the name memoryless simplification. + +At each step, all remaining edges are potential candidates for +collapsing and the one with the lowest cost is selected. + +The cost of collapsing an edge is given by the position chosen for the +vertex that replaces it. + +The replacement vertex position is computed as +the solution to a system of 3 linearly-independent linear equality constraints. +Each constraint is obtained by minimizing a quadratic objective function +subject to the previously computed constraints. + +There are several possible candidate constraints and each is considered in order of importance. +A candidate constraint might be incompatible with the previously accepted constraints, +in which case it is rejected and the next constraint is considered. + +Once 3 constraints have been accepted, the system is solved for the vertex position. + +The first constraints considered preserves the shape of the surface mesh boundaries +(in case the edge profile has boundary edges). +The next constraints preserve the total volume of the surface mesh. +The next constraints, if needed, optimize the local changes in volume and boundary shape. +Lastly, if a constraint is still needed (because the ones previously computed were incompatible), +a third (and last) constraint is added to favor equilateral triangles over elongated triangles. + +The cost is then a weighted sum of the shape, volume and boundary optimization terms, where the user specifies the unit weighting unit factor for each term. + +The local changes are computed independently for each edge using only +the triangles currently adjacent to it at the time when the edge +is about to be collapsed, that is, after all previous collapses. +Thus, the transitive path of minimal local changes yields at +the end a global change reasonably close to the absolute minimum. + +\subsection Surface_mesh_simplificationCostStrategyPolicies Cost Strategy Policies + +The cost strategy used by the algorithm is selected by means of two policies: +`GetPlacement` and `GetCost`. + +The `GetPlacement` policy is called to compute the new position +for the remaining vertex after the halfedge-collapse. It returns +an optional value, which can be absent, in which case the +remaining vertex is kept in its place. + +The `GetCost` policy is called to compute the cost +of collapsing an edge. This policy uses the placement to compute +the cost (which is an error measure) and determines the +ordering of the edges. + +The algorithm maintains an internal data structure (a mutable priority queue) +which allows each edge to be processed in increasing cost order. Such a data structure +requires some per-edge additional information, such as the edge's cost. +If the record of per-edge additional information occupies N bytes of storage, +simplifying a surface mesh of 1 million edges (a normal size) requires 1 million times N bytes +of additional storage. Thus, to minimize the amount of additional memory required to +simplify a surface mesh only the cost is attached to each edge and nothing else. + +But this is a tradeoff: the cost of a collapse is a function of the placement +(the new position chosen for the remaining vertex) so before `GetCost` +is called for each and every edge, `GetPlacement` must also be called to obtain +the placement parameter to the cost function. +But that placement, which is a 3D Point, is not attached to each and every edge since +that would easily triple the additional storage requirement. + +On the one hand, this dramatically saves on memory but on the other hand is +a processing waste because when an edge is effectively collapsed, `GetPlacement` +must be called again to know were to move the remaining vertex. + +Earlier prototypes shown that attaching the placement to the edge, thus avoiding one +redundant call to the placement function after the edge collapsed, has little +impact on the total running time. This is because the cost of an each edge is not just +computed once but changes several times during the process so the placement function +must be called several times just as well. Caching the placement can only avoid the +very last call, when the edge is collapsed, but not all the previous calls which +are needed because the placement (and cost) changes. + +\section Surface_mesh_simplificationAPI API + +\subsection Surface_mesh_simplificationAPIOverview API Overview + +Since the algorithm is free from robustness issues there is no need for exact predicates nor constructions and `Simple_cartesian` can be used safely. +\cgalFootnote{In the current version, 3.3, the LindstromTurk policies are not implemented for homogeneous coordinates, so a %Cartesian kernel must be used.} + +The simplification algorithm is implemented as the free template function +`Surface_mesh_simplification::edge_collapse()`. The function has two mandatory and several optional parameters. + +\subsection Surface_mesh_simplificationMandatoryParameters Mandatory Parameters + +There are two main parameters to the algorithm: the surface mesh to be simplified (in-place) and the stop predicate. + +The surface mesh to simplify must be a model of the `EdgeCollapsableSurfaceMesh` concept. +Many concrete surface mesh types, such as `Polyhedron_3` with only triangular faces, +become models of that concept via a technique known as +external adaptation, which is described in \cgalCite{cgal:sll-bgl-02} +and this Bgl web page: http://www.boost.org/libs/graph/doc/leda_conversion.html + +External adaptation is a way to add an interface to an +object without coercing the type of the object (which happens when you adapt it by means +of a wrapper). That is, the formal parameter to the `edge_collapse` function that +implements the simplification is the concrete surface mesh object itself, not an adaptor +which delegates the functionality to the concrete type. + +The stop predicate is called after each edge is selected for processing, before +it is classified as collapsible or not (thus before it is collapsed). If the stop predicate +returns `true` the algorithm terminates. + +\subsection Surface_mesh_simplificationOptionalNamed Optional Named Parameters + +The notion of named parameters was also introduced in the Bgl. You can read about it in \cgalCite{cgal:sll-bgl-02} or the following site: http://www.boost.org/libs/graph/doc/bgl_named_params.html. Named parameters allow the user to specify only those parameters which are really needed, by name, making the parameter ordering unimportant. + +Say there is a function `f()` that takes 3 parameters called `name`, `age` and `gender`, and you have variables `n,a and g` to pass as parameters to that function. Without named parameters, you would call it like this: `f(n,a,g)`, but with named parameters, you call it like this: `f(name(n).age(a).gender(g))`. + +That is, you give each parameter a name by wrapping it into a function whose name matches that of the parameter. The entire list of named parameters is really a composition of function calls separated by a dot (\f$ .\f$). Thus, if the function takes a mix of mandatory and named parameters, you use a comma to separate the last non-named parameter from the first named parameters, like this: + +`f(non_named_par0, non_named_pa1, name(n).age(a).gender(g)) ` + +When you use named parameters, the ordering is irrelevant, so this: `f(name(n).age(a).gender(g))` is equivalent to this: +`f(age(a).gender(g).name(n))`, and you can just omit any named parameter that has a default value. + +\subsection Surface_mesh_simplificationSampleCall Sample Call + +\code{.cpp} + +/* +surface_mesh : the surface_mesh to simplify +stop_predicate : policy indicating when the simplification must finish +vertex_index_map(vimap) : property-map giving each vertex a unique integer index +edge_index_map(eimap) : property-map giving each edge a unique integer index +edge_is_border_map(ebmap): property-map specifying whether an edge is a border edge or not +get_cost(cf) : function object computing the cost of a collapse +get_placement(pf) : function object computing the placement for the remaining vertex +visitor(vis) : function object tracking the simplification process +*/ + +int r = edge_collapse(surface_mesh + ,stop_predicate + ,vertex_index_map(vimap) + .edge_index_map(eimap) + .edge_is_border_map(ebmap) + .get_cost(cf) + .get_placement(pf) + .visitor(vis) + ); + +\endcode + +\subsection Surface_mesh_simplificationExamples Examples + +\subsection Surface_mesh_simplificationExampleUsinga Example Using a Default Polyhedron + +The following example illustrates the simplest of the cases.

The related task of simplifying a shape finds an approximation of the original shape using simpler curves. While previous works address these two issues sequentially, they are performed jointly using a unified framework based on optimal transport of measures. This new method provides benefits such as robustness to noise, preservation of sharp features and boundaries. It furthermore guarantees that the output is a simplicial complex. Transportation theory studies optimal transportations between a set M of n sources and a set F of n targets (both can for example be pointsets in R^2). Given a cost function c : R^2 x R^2 -> R^+, the goal is to find a bijection between M and F such that the sum of the costs c gets minimized. The optimal transport problem can also be defined between measures, and the paper views reconstruction and simplification tasks as such a transportation problem, where the input points are Dirac measure and the reconstructed simplicial complex is the support of a piecewise uniform measure. Given this theoretical background the algorithm then performs edge contractions in a greedy fashion w.r.t. the transportation cost, until the desired number of vertices are reached.In both cases the operation removes the edge `e` along with the 2 triangles adjacent to it.

Cost-driven methods, like the one in this package, produce slightly -less accurate simplifications but take up much less additional space, even none in some cases. +\section 2D_Reconstruction_SimplificationTrans Transportation Cost -The cost-driven method implemented in this package is mainly based on \cgalCite{cgal:lt-fmeps-98}, \cgalCite{cgal:lt-ems-99}, with contributions from \cgalCite{hddms-mo-93}, \cgalCite{gh-ssqem-97} -and \cgalCite{degn-tpec-98}. -The algorithm proceeds in two stages. In the first stage, called collection stage, -an initial collapse cost is assigned to each and every edge in the surface mesh. -Then in the second stage, called collapsing stage, edges are -processed in order of increasing cost. Some processed edges are collapsed -while some are just discarded. Collapsed edges are replaced by a vertex and the collapse -cost of all the edges now incident on the replacement vertex is recalculated, affecting -the order of the remaining unprocessed edges. - -Not all edges selected for processing are collapsed. A processed edge can be discarded -right away, without being collapsed, if it does not satisfy certain topological -and geometric conditions. - -The algorithm presented in \cgalCite{gh-ssqem-97} contracts (collapses) arbitrary vertex pairs and not -only edges by considering certain vertex pairs as forming a pseudo-edge and proceeding to collapse -both edges and pseudo-edges in the same way as in \cgalCite{cgal:lt-fmeps-98}, \cgalCite{cgal:lt-ems-99} ( -which is the algorithm implemented here). However, contracting an arbitrary vertex-pair may result in a non-manifold surface mesh, but the current state of this package can only deal with manifold surface meshes, thus, it can only collapse edges. That is, this package cannot be used as a framework for vertex contraction. - -\section Surface_mesh_simplificationCost Cost Strategy - -The specific way in which the collapse cost and vertex placement is -calculated is called the cost strategy. The user can choose -different strategies in the form of policies and related parameters, -passed to the algorithm. - -The current version of the package provides a set of policies implementing -two strategies: the Lindstrom-Turk strategy, which is the default, and -a strategy consisting of an edge-length cost with an optional -midpoint placement (much faster but less accurate). - -\subsection SurfaceMeshSimplificationLindstromTurkStrategy Lindstrom-Turk Cost and Placement Strategy - -The main characteristic of the strategy presented in -\cgalCite{cgal:lt-fmeps-98}, \cgalCite{cgal:lt-ems-99} is that the simplified surface mesh -is not compared at each step with the original surface mesh (or the surface mesh -at a previous step) so there is no need to keep extra information, -such as the original surface mesh or a history of the local changes. Hence -the name memoryless simplification. - -At each step, all remaining edges are potential candidates for -collapsing and the one with the lowest cost is selected. - -The cost of collapsing an edge is given by the position chosen for the -vertex that replaces it. - -The replacement vertex position is computed as -the solution to a system of 3 linearly-independent linear equality constraints. -Each constraint is obtained by minimizing a quadratic objective function -subject to the previously computed constraints. - -There are several possible candidate constraints and each is considered in order of importance. -A candidate constraint might be incompatible with the previously accepted constraints, -in which case it is rejected and the next constraint is considered. - -Once 3 constraints have been accepted, the system is solved for the vertex position. - -The first constraints considered preserves the shape of the surface mesh boundaries -(in case the edge profile has boundary edges). -The next constraints preserve the total volume of the surface mesh. -The next constraints, if needed, optimize the local changes in volume and boundary shape. -Lastly, if a constraint is still needed (because the ones previously computed were incompatible), -a third (and last) constraint is added to favor equilateral triangles over elongated triangles. - -The cost is then a weighted sum of the shape, volume and boundary optimization terms, where the user specifies the unit weighting unit factor for each term. - -The local changes are computed independently for each edge using only -the triangles currently adjacent to it at the time when the edge -is about to be collapsed, that is, after all previous collapses. -Thus, the transitive path of minimal local changes yields at -the end a global change reasonably close to the absolute minimum. - -\subsection Surface_mesh_simplificationCostStrategyPolicies Cost Strategy Policies - -The cost strategy used by the algorithm is selected by means of two policies: -`GetPlacement` and `GetCost`. - -The `GetPlacement` policy is called to compute the new position -for the remaining vertex after the halfedge-collapse. It returns -an optional value, which can be absent, in which case the -remaining vertex is kept in its place. - -The `GetCost` policy is called to compute the cost -of collapsing an edge. This policy uses the placement to compute -the cost (which is an error measure) and determines the -ordering of the edges. - -The algorithm maintains an internal data structure (a mutable priority queue) -which allows each edge to be processed in increasing cost order. Such a data structure -requires some per-edge additional information, such as the edge's cost. -If the record of per-edge additional information occupies N bytes of storage, -simplifying a surface mesh of 1 million edges (a normal size) requires 1 million times N bytes -of additional storage. Thus, to minimize the amount of additional memory required to -simplify a surface mesh only the cost is attached to each edge and nothing else. - -But this is a tradeoff: the cost of a collapse is a function of the placement -(the new position chosen for the remaining vertex) so before `GetCost` -is called for each and every edge, `GetPlacement` must also be called to obtain -the placement parameter to the cost function. -But that placement, which is a 3D Point, is not attached to each and every edge since -that would easily triple the additional storage requirement. - -On the one hand, this dramatically saves on memory but on the other hand is -a processing waste because when an edge is effectively collapsed, `GetPlacement` -must be called again to know were to move the remaining vertex. - -Earlier prototypes shown that attaching the placement to the edge, thus avoiding one -redundant call to the placement function after the edge collapsed, has little -impact on the total running time. This is because the cost of an each edge is not just -computed once but changes several times during the process so the placement function -must be called several times just as well. Caching the placement can only avoid the -very last call, when the edge is collapsed, but not all the previous calls which -are needed because the placement (and cost) changes. - -\section Surface_mesh_simplificationAPI API +\section 2D_Reconstruction_SimplificationAPI API \subsection Surface_mesh_simplificationAPIOverview API Overview @@ -264,60 +93,39 @@ That is, you give each parameter a name by wrapping it into a function whose nam When you use named parameters, the ordering is irrelevant, so this: `f(name(n).age(a).gender(g))` is equivalent to this: `f(age(a).gender(g).name(n))`, and you can just omit any named parameter that has a default value. -\subsection Surface_mesh_simplificationSampleCall Sample Call +\subsection 2D_Reconstruction_SimplificationSample Sample Call \code{.cpp} /* -surface_mesh : the surface_mesh to simplify -stop_predicate : policy indicating when the simplification must finish -vertex_index_map(vimap) : property-map giving each vertex a unique integer index -edge_index_map(eimap) : property-map giving each edge a unique integer index -edge_is_border_map(ebmap): property-map specifying whether an edge is a border edge or not -get_cost(cf) : function object computing the cost of a collapse -get_placement(pf) : function object computing the placement for the remaining vertex -visitor(vis) : function object tracking the simplification process +K : Kernel is the geometric kernel, used for the reconstruction and simplification task. +InputIterator : InputIterator is the iterator type of the algorithm input. +PointPMap : is a PropertyMap for accessing the input points. +MassPMap : MassPMap is a PropertyMap for accessing the input points' */ -int r = edge_collapse(surface_mesh - ,stop_predicate - ,vertex_index_map(vimap) - .edge_index_map(eimap) - .edge_is_border_map(ebmap) - .get_cost(cf) - .get_placement(pf) - .visitor(vis) - ); + +Reconstruction_simplification_2 + rs2(points.begin(), points.end(), point_pmap, mass_pmap); + + rs2.initialize(); + + rs2.reconstruct(100); + + rs2.extract_solid_eges(); \endcode -\subsection Surface_mesh_simplificationExamples Examples +\subsection 2D_Reconstruction_SimplificationExamples Examples -\subsection Surface_mesh_simplificationExampleUsinga Example Using a Default Polyhedron +\subsection 2D_Reconstruction_SimplificationExampleSimple Simple reconstruction Example The following example illustrates the simplest of the cases.

The function has two mandatory and several optional parameters. - -\subsection Surface_mesh_simplificationMandatoryParameters Mandatory Parameters - -There are two main parameters to the algorithm: the surface mesh to be simplified (in-place) and the stop predicate. - -The surface mesh to simplify must be a model of the `EdgeCollapsableSurfaceMesh` concept. -Many concrete surface mesh types, such as `Polyhedron_3` with only triangular faces, -become models of that concept via a technique known as -external adaptation, which is described in \cgalCite{cgal:sll-bgl-02} -and this Bgl web page: http://www.boost.org/libs/graph/doc/leda_conversion.html - -External adaptation is a way to add an interface to an -object without coercing the type of the object (which happens when you adapt it by means -of a wrapper). That is, the formal parameter to the `edge_collapse` function that -implements the simplification is the concrete surface mesh object itself, not an adaptor -which delegates the functionality to the concrete type. - -The stop predicate is called after each edge is selected for processing, before -it is classified as collapsible or not (thus before it is collapsed). If the stop predicate -returns `true` the algorithm terminates. - -\subsection Surface_mesh_simplificationOptionalNamed Optional Named Parameters - -The notion of named parameters was also introduced in the Bgl. You can read about it in \cgalCite{cgal:sll-bgl-02} or the following site: http://www.boost.org/libs/graph/doc/bgl_named_params.html. Named parameters allow the user to specify only those parameters which are really needed, by name, making the parameter ordering unimportant. - -Say there is a function `f()` that takes 3 parameters called `name`, `age` and `gender`, and you have variables `n,a and g` to pass as parameters to that function. Without named parameters, you would call it like this: `f(n,a,g)`, but with named parameters, you call it like this: `f(name(n).age(a).gender(g))`. - -That is, you give each parameter a name by wrapping it into a function whose name matches that of the parameter. The entire list of named parameters is really a composition of function calls separated by a dot (\f$ .\f$). Thus, if the function takes a mix of mandatory and named parameters, you use a comma to separate the last non-named parameter from the first named parameters, like this: - -`f(non_named_par0, non_named_pa1, name(n).age(a).gender(g)) ` - -When you use named parameters, the ordering is irrelevant, so this: `f(name(n).age(a).gender(g))` is equivalent to this: -`f(age(a).gender(g).name(n))`, and you can just omit any named parameter that has a default value. +The API design is chosen in such a way that most of the implementation details are hidden from the user, i.e., the only class +exposed to the user is the Reconstruction_simplification_2 class. \subsection 2D_Reconstruction_SimplificationSample Sample Call diff --git a/Reconstruction_simplification_2/include/CGAL/Reconstruction_simplification_2.h b/Reconstruction_simplification_2/include/CGAL/Reconstruction_simplification_2.h index 01d36491244..d35918c16b2 100644 --- a/Reconstruction_simplification_2/include/CGAL/Reconstruction_simplification_2.h +++ b/Reconstruction_simplification_2/include/CGAL/Reconstruction_simplification_2.h @@ -52,17 +52,18 @@ namespace CGAL { \brief The class `Reconstruction_simplification_2` is the base class designed to execute the reconstruction and simplification tasks. -\details This class takes as input a collection of point-mass pairs $. +\details This class takes as input a collection of point-mass pairs, where both +the points and their masses are accessed using PropertyMaps. -\tparam Kernel is the geometric kernel, used for the reconstruction and simplification task. +\tparam Kernel is the geometric kernel, used for the reconstruction and + simplification task. \tparam InputIterator is the iterator type of the algorithm input. -\tparam PointPMap is a PropertyMap for accessing the input points. +\tparam PointPMap is a model of ReadablePropertyMap with a value_type = Point_2 -\tparam MassPMap is a PropertyMap for accessing the input points' - mass information. +\tparam MassPMap is a model of ReadablePropertyMap with a value_type = FT */ template From f25502e1da129400a182174e2858a9fe36a0fffa Mon Sep 17 00:00:00 2001 From: Ivo Vigan Date: Mon, 7 Jul 2014 15:36:47 +0200 Subject: [PATCH 021/201] Documentation WIP --- .../PackageDescription.txt | 13 +++--------- .../Reconstruction_Simplification_2.txt | 21 +++++++++---------- .../CGAL/Reconstruction_simplification_2.h | 20 +++++++++++------- 3 files changed, 26 insertions(+), 28 deletions(-) diff --git a/Reconstruction_simplification_2/doc/Reconstruction_simplification_2/PackageDescription.txt b/Reconstruction_simplification_2/doc/Reconstruction_simplification_2/PackageDescription.txt index da888c3e4d7..7a52c4eb397 100644 --- a/Reconstruction_simplification_2/doc/Reconstruction_simplification_2/PackageDescription.txt +++ b/Reconstruction_simplification_2/doc/Reconstruction_simplification_2/PackageDescription.txt @@ -1,4 +1,7 @@ /// \defgroup PkgReconstructionSimplification2 2D Reconstruction Simplification Reference + +/// \defgroup PkgReconstructionSimplification2Classes Classes +/// \ingroup PkgReconstructionSimplification2 /*! \addtogroup PkgReconstructionSimplification2 \cgalPkgDescriptionBegin{2D Reconstruction Simplification, PkgReconstructionSimplification2Summary} @@ -16,15 +19,5 @@ \cgalPkgShortInfoEnd \cgalPkgDescriptionEnd -\cgalClassifedRefPages - -## Concepts ## -- `PointPMap` -- `MassPMap` - - -## Classes ## -- `CGAL::Reconstruction_simplification_2` - */ diff --git a/Reconstruction_simplification_2/doc/Reconstruction_simplification_2/Reconstruction_Simplification_2.txt b/Reconstruction_simplification_2/doc/Reconstruction_simplification_2/Reconstruction_Simplification_2.txt index d9ba214bbe1..b72ef48e525 100644 --- a/Reconstruction_simplification_2/doc/Reconstruction_simplification_2/Reconstruction_Simplification_2.txt +++ b/Reconstruction_simplification_2/doc/Reconstruction_simplification_2/Reconstruction_Simplification_2.txt @@ -1,16 +1,15 @@ namespace CGAL { /*! -\mainpage 2D Reconstruction Simplification +\mainpage User Manual \anchor Chapter_2D_Reconstruction_Simplification \cgalAutoToc \authors Fernando de Goes, Pierre Alliez, Ivo Vigan -\image html overview.png -\image latex overview.png -\section 2D_Reconstruction_SimplificationIntroduction Introduction + +\section Reconstruction_simplification_2Introduction Introduction \cgalFigureBegin{2D_Reconstruction_Simplification_process,process.png} @@ -35,18 +34,18 @@ After that, edges which carry little mass can be filtered out. -\section 2D_Reconstruction_SimplificationOverview Overview of the Reconstruction Process +\section Reconstruction_simplification_2Overview Overview of the Reconstruction Process The task addressed is to reconstruct a shape from noisy data $S$ in $R^2$, i.e. give a (noisy) set of points, find a shape which best approximates the non-noise subset of $S$.

The related task of simplifying a shape finds an approximation of the original shape using simpler curves. While previous works address these two issues sequentially, they are performed jointly using a unified framework based on optimal transport of measures. This new method provides benefits such as robustness to noise, preservation of sharp features and boundaries. It furthermore guarantees that the output is a simplicial complex. Transportation theory studies optimal transportations between a set M of n sources and a set $F$ of n targets (both can for example be point sets in $R^2$). Given a cost function $c : R^2 x R^2 -> R^+$, the goal is to find a bijection between M and F such that the sum of the costs c gets minimized. The optimal transport problem can also be defined between measures, and the paper views reconstruction and simplification tasks as such a transportation problem, where the input points are Dirac measure and the reconstructed simplicial complex is the support of a piecewise uniform measure. Given this theoretical background the algorithm then performs edge contractions in a greedy fashion w.r.t. the transportation cost, until the desired number of vertices are reached. @@ -96,21 +94,8 @@ Reconstruction_simplification_2 rs2.initialize(); - rs2.reconstruct(100); + rs2.reconstruct(100); //perform 100 contraction steps - CGAL::List_output list_output; - - rs2.extract_solid_elements(list_output); - - for (Output_Vertex_Iterator it = list_output.vertices_start(); - it != list_output.vertices_beyond(); it++) { - ... - } - - for (Output_Edge_Iterator it = list_output.edges_start(); - it != list_output.edges_beyond(); it++) { - ... - } \endcode @@ -118,15 +103,25 @@ Reconstruction_simplification_2 \subsection Reconstruction_simplification_2Examples Examples +\subsection Reconstruction_simplification_2ExampleSimple Simple Reconstruction Example + + +The following example shows a simple use case of the Reconstruction_simplification_2 package. +It works by first reading a collection of input points from an xy-file.

It starts by putting a bounding box around the input points S and computes the Delaunay Triangulation T_0 on S. T_0 is the first output simplex, which is made courser in subsequent iterations by repeated edge contractions.

The related task of simplifying a shape finds an approximation of the original shape using simpler curves. While previous works address these two issues sequentially, they are performed jointly using a unified framework based on optimal transport of measures. This new method provides benefits such as robustness to noise, preservation of sharp features and boundaries. It furthermore guarantees that the output is a simplicial complex. Transportation theory studies optimal transportations between a set M of n sources and a set $F$ of n targets (both can for example be point sets in $R^2$). Given a cost function $c : R^2 x R^2 -> R^+$, the goal is to find a bijection between M and F such that the sum of the costs c gets minimized. The optimal transport problem can also be defined between measures, and the paper views reconstruction and simplification tasks as such a transportation problem, where the input points are Dirac measure and the reconstructed simplicial complex is the support of a piecewise uniform measure. Given this theoretical background the algorithm then performs edge contractions in a greedy fashion w.r.t. the transportation cost, until the desired number of vertices are reached. +While previous works address the reconstruction and simplification tasks sequentially, they are performed jointly using the unified framework based on optimal transport of measures.

For a point to vertex assignment, the cost is simply the sum of the weighted \f$L_2 \f$-distances of all the points assigned to the given vertex. -For an edge of the simplex, the optimal plan and its cost is computed indirectly, by decomposing the transportation plan into a tangential and normal component. While the normal plan is simply an orthogonal projection, the tangential plan is a bit more involved. In order to compute it, we decompose an edge $e$ into bins. This decomposition is done by sorting the projected points on $e$ and choosing the length of the $i$-th bin as $(m_i/M_e)|e|$. Each projected point $q_i$ on $e$ is then spread over the $i$-th bin. such that we get a uniform measure on $e$, which is then used to define an optimal transport from the input points to $e$. +For an edge of the simplex, the optimal plan and its cost is computed indirectly, by decomposing the transportation plan into a tangential and normal component.

This new method provides benefits such as robustness to noise, preservation of sharp features and boundaries. It furthermore guarantees that the output is a simplicial complex. Transportation theory studies optimal transportations between a set \f$M\f$ of \f$n\f$ sources and a set \f$F \f$ of \f$n\f$ targets (both can for example be point sets in \f$ \mathbb{R}^2 \f$). Given a cost function \f$c : \mathbb{R}^2 \times \mathbb{R}^2 \rightarrow \mathbb{R}^+ \f$, the goal is to find a bijection between \f$M\f$ and \f$F\f$ such that the sum of the costs \f$c\f$ gets minimized. The optimal transport problem can also be defined between measures, and the paper views reconstruction and simplification tasks as such a transportation problem, where the input points are Dirac measure and the reconstructed simplicial complex is the support of a piecewise uniform measure. The algorithm then performs edge contractions in a greedy fashion w.r.t. the transportation cost, until the desired number of vertices are reached. +While previous works address the reconstruction and simplification tasks sequentially, here they are performed jointly using a unified framework based on optimal transport of measures.

The algorithm then performs edge contractions in a greedy fashion w.r.t. the transportation cost, until the desired number of vertices are reached or a predefined iteration threshold has been exceeded. \section Reconstruction_simplification_2Trans Optimal Transport Formulation -The quality of an output simplex is measured as the total transportation cost of the input points to the assigned simplex vertices and edges. -For the transportation cost, the 2-Wasserstein metric is chosen which is also known the Earth Mover Distance, and intuitively +The quality of the output simplex is measured as the total transportation cost of the input points to their assigned simplex vertices and edges. +For the transportation cost, the 2-Wasserstein metric is chosen, also known the Earth Mover Distance, it intuitively corresponds to the minimum cost of turning a (unit) pile of sand into a given shape, where the cost is measured using the \f$L_2 \f$ distances. \subsection Reconstruction_simplification_2TransCost Transportation Plan & Cost from Points to Simplices -Assuming that the algorithm is given an output simplex \f$T \f$, and a point-to-simplex assignment which maps every input point to either an edge or a vertex of \f$T \f$, -the total transportation cost is then computed using the following rules.

While the normal plan is simply an orthogonal projection, the tangential plan is a bit more involved. In order to compute it, we decompose an edge \f$e \f$ into bins. This decomposition is done by sorting the projected points on \f$e \f$ and choosing the length of the \f$i \f$-th bin as \f$(m_i / M_e)|e| \f$, with \f$\f$.

This new method provides benefits such as robustness to noise, preservation of sharp features and boundaries. It furthermore guarantees that the output is a simplicial complex. Transportation theory studies optimal transportations between a set \f$M\f$ of \f$n\f$ sources and a set \f$F \f$ of \f$n\f$ targets (both can be point sets in \f$ \mathbb{R}^2 \f$). Given a cost function \f$c : \mathbb{R}^2 \times \mathbb{R}^2 \rightarrow \mathbb{R}^+ \f$, the goal is to find a bijection between \f$M\f$ and \f$F\f$ such that the sum of the costs \f$c\f$ gets minimized. The optimal transport problem can also be defined between measures, and here we view the reconstruction and simplification tasks as such a transportation problem, where the input points are Dirac measure and the reconstructed simplicial complex is the support of a piecewise uniform measure. The algorithm then performs edge contractions in a greedy fashion w.r.t. the transportation cost, until the desired number of vertices are reached or a predefined iteration threshold has been exceeded. +While previous work address the reconstruction and simplification tasks sequentially, here they are performed jointly using a unified framework based on optimal transport of measures.

While the normal plan is simply an orthogonal projection, the tangential plan is slightly more involved. In order to compute it, we decompose \f$e \f$ into bins. This decomposition is done by sorting the projected points on \f$e \f$ and choosing the length of the \f$i \f$-th bin as \f$(m_i / M_e)|e| \f$, with \f$ m_i \f$ denoting the mass of point of the corresponding projected point \f$q_i \f$, while \f$M_e \f$ denotes the sum of the mass of all points assigned to \f$ e \f$ and \f$ |e| \f$ denotes the length of \f$ e \f$. Each projected point \f$q_i \f$ on \f$e \f$ is then spread over the \f$i \f$-th bin. such that we get a uniform measure on \f$e \f$, which is then used to define an optimal transport from the input points to \f$e\f$. +For an edge \f$e \f$ of the simplex, the optimal transportation plan and its cost is computed indirectly, by decomposing the transportation plan into a tangential and normal component.

This new method provides benefits such as robustness to noise, preservation of sharp features and boundaries. It furthermore guarantees that the output is a simplicial complex. Transportation theory studies optimal transportations between a set \f$M\f$ of \f$n\f$ sources and a set \f$F \f$ of \f$n\f$ targets (both can be primitives in various dimensions.). Given a cost function \f$c : \mathbb{R}^2 \times \mathbb{R}^2 \rightarrow \mathbb{R}^+ \f$, the goal is to find a mapping between \f$M\f$ and \f$F\f$ such that the sum of the costs \f$c\f$ gets minimized. The optimal transport problem can also be defined between measures, and here we view the reconstruction and simplification tasks as such a transportation problem, where the input points are Dirac measure and the reconstructed simplicial complex is the support of a piecewise uniform measure. The algorithm then performs edge contractions in a greedy fashion w.r.t. the transportation cost, until the desired number of vertices are reached or a predefined iteration threshold has been exceeded.

While the normal plan is simply an orthogonal projection, the tangential plan is slightly more involved. In order to compute it, the algorithm decomposes \f$e \f$ into bins. This decomposition is done by sorting the projected points on \f$e \f$ and choosing the length of the \f$i \f$-th bin as \f$(m_i / M_e)|e| \f$, with \f$ m_i \f$ denoting the mass of point of the corresponding projected point \f$q_i \f$, while \f$M_e \f$ denotes the sum of the mass of all points assigned to \f$ e \f$ and \f$ |e| \f$ denotes the length of \f$ e \f$. Each projected point \f$q_i \f$ on \f$e \f$ is then spread over the \f$i \f$-th bin. such that we get a uniform measure on \f$e \f$, which is then used to define an optimal transport from the input points to \f$e\f$. Because the transport cost is based on the \f$L_2 \f$-distance the decomposition of the transportation plan into a tangential and normal component, the above procedure yields a closed formula for the cost. \cgalFigureBegin{2D_Reconstruction_Simplification_tangentialplan,tangentialplan.png} -Illustration of the bins of a simplicial-edge induced by the input points assigned to the edge.

Since disregarding edges which do not preserve the embedding of the triangulation can severely affect the performance of the greedy approach to optimal transport, the collapse operator is modified by adding a local flip procedure which makes every edge collapsible. The transportation plan is approximated by assigning each input point temporarily to the closest simplex edge. After this partitioning of the input points w.r.t. the edges, all the points temporarily assigned to a given edge are being assigned to it permanently if and only if the corresponding transportation costs are less than the transportation cost for each of the two vertices of the edge. Otherwise each of the points is assigned to the cheaper of the two vertices. This process of edge contraction and transportation plan update is repeated until the desired number of vertices, specified by the users, has been reached. After that, edges which carry little mass can be filtered out and the remaining edges are reported as reconstructing the input shape. - - -While previous work address the reconstruction and simplification tasks sequentially, here they are performed jointly using a framework based on optimal transport of measures. It furthermore guarantees that the output is a simplicial complex. Transportation theory studies optimal transportations between a set \f$M\f$ of \f$n\f$ sources and a set \f$F \f$ of \f$n\f$ targets (both can be primitives in various dimensions.). Given a cost function \f$c : \mathbb{R}^2 \times \mathbb{R}^2 \rightarrow \mathbb{R}^+ \f$, the goal is to find a mapping between \f$M\f$ and \f$F\f$ such that the sum of the costs \f$c\f$ gets minimized. The optimal transport problem can also be defined between measures, and here we view the reconstruction and simplification tasks as such a transportation problem, where the input points are Dirac measure and the reconstructed simplicial complex is the support of a piecewise uniform measure. The algorithm then performs edge contractions in a greedy fashion w.r.t. the transportation cost, until the desired number of vertices are reached or a predefined iteration threshold has been exceeded. - - -\section Reconstruction_simplification_2Trans Optimal Transport Formulation - -The quality of the output simplex is measured as the total transportation cost of the input points to their assigned simplex vertices and edges. -For the transportation cost, the 2-Wasserstein metric is chosen which intuitively -corresponds to the minimum cost of turning a (unit) pile of sand into a given shape, when the cost is measured using the \f$L_2 \f$ distance. - -\subsection Reconstruction_simplification_2TransCost Transportation Plan & Cost from Points to Simplices - -Assuming that the algorithm is given an output simplex \f$T \f$ and a point-to-simplex assignment which maps every input point to either an edge or a vertex of \f$T \f$, -the total transportation cost is computed using the following assignment rules: For a point to vertex assignment, the transportation cost is simply the sum of the weighted \f$L_2 \f$-distance of all the points assigned to the given vertex. - -For an edge \f$e \f$ of the simplex, the optimal transportation plan and its cost is computed indirectly, by decomposing the transportation plan into a tangential and normal component. While the normal plan is simply an orthogonal projection, the tangential plan is slightly more involved. In order to compute it, the algorithm decomposes \f$e \f$ into bins. This decomposition is done by sorting the projected points on \f$e \f$ and choosing the length of the \f$i \f$-th bin as \f$(m_i / M_e)|e| \f$, with \f$ m_i \f$ denoting the mass of point of the corresponding projected point \f$q_i \f$, while \f$M_e \f$ denotes the sum of the mass of all points assigned to \f$ e \f$ and \f$ |e| \f$ denotes the length of \f$ e \f$. Each projected point \f$q_i \f$ on \f$e \f$ is then spread over the \f$i \f$-th bin. such that we get a uniform measure on \f$e \f$, which is then used to define an optimal transport from the input points to \f$e\f$. Because the transport cost is based on the \f$L_2 \f$-distance the decomposition of the transportation plan into a tangential and normal component, the above procedure yields a closed formula for the cost. - -\cgalFigureBegin{2D_Reconstruction_Simplification_plan,plan.png} -Illustration of the bins of a simplicial-edge induced by the input points assigned to the edge.

To chose the next edge, a collapse operator is simulated for each feasible edge, i.e., edges which neither introduce overlaps nor fold-overs in the triangulation. The next edge \f$ e \f$ for collapse is chosen according to the overall cost of the transportation plan for \f$ T \setminus e \f$, where the cheapest overall cost is preferred. Since disregarding edges which do not preserve the embedding of the triangulation can severely affect the performance of the greedy approach to optimal transport, the collapse operator is modified by adding a local flip procedure which makes every edge collapsible. - The transportation plan is approximated by assigning each input point temporarily to the closest simplex edge. After this partitioning of the input points w.r.t. the edges, all the points temporarily assigned to a given edge are being assigned to it permanently if and only if the corresponding transportation costs are less than the transportation cost for each of the two vertices of the edge. Otherwise each of the points is assigned to the cheaper of the two vertices. This process of edge contraction and transportation plan update is repeated until the desired number of vertices, specified by the users, has been reached. After that, edges which carry little mass can be filtered out and the remaining edges are reported as reconstructing the input shape. */ diff --git a/Reconstruction_simplification_2/include/CGAL/Reconstruction_simplification_2.h b/Reconstruction_simplification_2/include/CGAL/Reconstruction_simplification_2.h index f38a3213def..5b766261c76 100644 --- a/Reconstruction_simplification_2/include/CGAL/Reconstruction_simplification_2.h +++ b/Reconstruction_simplification_2/include/CGAL/Reconstruction_simplification_2.h @@ -191,10 +191,10 @@ protected: /*!

More specifically, the input point set is seen as a discrete measure, ie, a set of pointwise masses. The goal is to find a 0-1 simplicial complex where the edges are the support of a piecewise uniform measure (line density of masses) and the vertices are the support of a discrete measure. Approximating the input point set in our context translates into approximating the input discrete measure by another measure composed of line segments and points. +The approximation error is derived from the theory of optimal transportation between geometric measures. More specifically, the input point set is seen as a discrete measure, i.e., a set of pointwise masses. The goal is to find a 0-1 simplicial complex where the edges are the support of a piecewise uniform measure (line density of masses) and the vertices are the support of a discrete measure. Approximating the input point set in our context translates into approximating the input discrete measure by another measure composed of line segments and points. The algorithm performs a fine to coarse simplification of a triangulation. It starts by putting a bounding box around the input points \f$S\f$ and computes the Delaunay Triangulation \f$ T_0 \f$ on a subset of \f$ S \f$. \f$ T_0 \f$ is the first output simplex, which is simplified in subsequent iterations by repeated edge collapses. To chose the next edge, a collapse operator is simulated for each feasible edge, i.e., edges which neither introduce overlaps nor fold-overs in the triangulation. The next edge \f$ e \f$ for collapse is chosen according to the overall cost of the transportation plan for \f$ T \setminus e \f$, where the cheapest overall cost is preferred. Since disregarding edges which do not preserve the embedding of the triangulation can severely affect the performance of the greedy approach to optimal transport, the collapse operator is modified by adding a local flip procedure which makes every edge collapsible.
