General software features

Skeletons suffer from the lack of stability with respect to noise. This is why, in real applications, skeleton filtering is a
crucial issue. This software implements recently introduced methods for obtaining robust, filtered Euclidean skeletons in 2D and 3D discrete spaces.

Context in which the software is used

This software has been built for finding and validating the results of the related publications.
