Hilditch Skeletonization

Category: Image Filters
Description: A function to skeletonize a binary image using the Hilditch Algorithm. For more details see http://cgm.cs.mcgill.ca/~godfried/teaching/projects97/azar/skeleton.html A binary image must be passed into the function. The function will carry out repeated skeletonizing passes, until no further subtractions from the image occur. A binary image is returned. This is too slow to be of much use, but some interesting binary image maths is included.
Comments: The Hilditch algorithm is not without its flaws - it will break some lines. Also this method is very slow for large images.
