A Pseudo-Distance Map for the Segmentation-Free Skeletonization of Gray-Scale Images


In this paper, we introduce a new tool, called a pseudodistance map (PDM), for extracting skeletons from grayscale images without region segmentation or edge detection. Given an edge-strength function (ESF) of a gray-scale image, the PDM is computed from the ESF using the partial differential equations we propose. The PDM can be thought of as a relaxed… (More)
