\subsubsection Surface_mesh_segmentationPostprocessing Postprocessing on Raw SDF Values
After having calculated the raw SDF value for each facet, several post-processing steps are applied.
First, facets with no SDF values are assigned the average SDF value of their one-ring edge-adjacent neighbors. If there is still a facet having no SDF value,
First, facets with no SDF values are assigned the average SDF value of their edge-adjacent neighbors. If there is still a facet having no SDF value,
the minimum valid SDF value assigned to it. Note that this step is not inherited from the paper.
The main reason for not assigning 0 to facets with no SDF values is that it can obstruct log-normalization process which takes place at the beginning of `segment_from_sdf_values()`.

* Post-processing steps applied are:
* - Facets with -1.0 SDF values are assigned the average SDF value of their one-ring edge-adjacent neighbors.
* - Facets with -1.0 SDF values are assigned the average SDF value of their edge-adjacent neighbors.
* If there is still a facet having -1.0 SDF value, the minimum valid SDF value assigned to it. Note that this step is not inherited from the paper.
* The main reason for not assigning 0 to facets with no SDF values (i.e. -1.0) is that it can obstruct log-normalization process which takes place at the beginning of `CGAL::segment_from_sdf_values`.
* - SDF values are smoothed with bilateral filtering.
