-\cgalFigureRef{icc_diff_radius} shows how the mean curvature changes depending on
-the named parameter `ball_radius`, which can be set to a value > 0 to get a smoother
-distribution of values and "diffuses" the extreme values of curvatures across the mesh.
+First, \cgalFigureRef{icc_measures} first illustrates various curvature measure on a triangular mesh.

+When changing the integration ball radius, we obtain a scale space of curvature measure that can be used to tackle possible noise in the input as illustrated in the second row (mean curvature only with fixed colormap ranges and ball radii in {0.02,0.03,0.04,0.05}).

 a curvature value to each vertex.
