AN EFFICIENT METHOD FOR OBTAINING MORPHOLOGICAL SKELETONS

A new method using gray-scale morphological erosion is proposed to obt ain the morphological skeleton of a discrete binary image. The full mo rphological skeleton is the union of a finite number of skeleton subse ts. We also show that gray-scale erosion in this method can be replace d by a simpler operation to further improve computation time. Two effi cient algorithms,based on the proposed approach are presented.
