Skeleton Extraction for Polygonal Models

Description:

Skeletons are used to capture the essence of shapes. For 3D boundary representations in the form of polygonal meshes, skeletons can be created in the form of internal skeletons or as external skeletons on the surface of the meshes. This work describes techniques to extract these shape descriptors and demonstrates applications such as shape matching and shape compression.
