Skeletons

Detailed Description

Skeletons result from sequential iterations of thinnings with specific composite SEs that generate a medial axis of the input set. This medial axis are called skeleton. It consists of a compact representation which preserves only those points of a set whose minimum distance to the boundary of the set reaches at least two distinct boundary points.
