Morphological skeleton

In digital image processing, morphological skeleton is a skeleton (or medial axis) representation of a shape or binary image, computed by means of morphological operators. Morphological skeletons are of two kinds: * Those defined by means of morphological openings, from which the original shape can be reconstructed, * Those computed by means of the hit-or-miss transform, which preserve the shape's topology.
