The files in this package comprise the Matlab implementation of a method for skeletonizing binary images. These are my own implementation
of a skeletonization method communicated to me by Alex Telea
(http://www.win.tue.nl/~alext/). See his papers for more details.
Skeletonization is (roughly speaking) the "thinning" of a binary image or silhouette to a one-pixel width spine. The image processing toolbox provides support for skeletonization via the bwmorph function, but its results do not always conform with our intuition. I have found that the approach used herein usually generates a more pleasing result.
There is also a routine for locating endpoints and junctions in skeletonized images.
(Note: This code has not been optimized for speed.)
Bug fix 7/18/07: In rare instances, isolated points would incorrectly be assigned an infinite value for skg.
