Paper Abstract

An iterated parallel algorithm to get the labeled skeleton of a digital figure F is presented. At every iteration, the current 8-connected contour is identified and the pixels preventing contour simplicity are taken as the skeletal pixels. The set of the skeletal pixels has all the properties generally satisfied by the skeleton, except for unit width. This property is enjoyed if one iteration of a standard parallel thinning algorithm is applied. Every skeletal pixel is assigned a label indicating the first iteration of the process at which it has been recognized as a skeletal pixel. Such a label is equal to the 4-distance of the pixel from the complement of F. The obtained labeled skeleton coincides with the skeleton one could get by skeletonizing the 4-distance transform of F.
