BinarySkeleton  Method

Description         This function will morphologically skeletonize the binary image. The function works for only 1 bit per pixel images. The binary skeletonization of an object defines a unique compressed geometrical representation of the object. Skeletonization is often referred to as the Medial Axis Transform. Morphological skeleton is processed by binary thinning operation several times iteratively until no further changes occur.
