Boundary detection and skeletonization with a massively parallel architecture
Maurice Milgram, T. De Saint Pierre · IEEE Transactions on Pattern Analysis and Machine Intelligence · 1990
A massively parallel architecture called TOSCA (tokens sending cellular automation) is presented that performs edge pixel detection and skeletonization in the image processing area. Each cell of this cellular automaton has a very reduced set of instructions and a very small amount of memory. The computation is based on token propagation, counting devices, and local processing. The skeletonization method is based on the Chamfer distance.>
