Matlab codes for active contour without edges (levelset based)

Somebody implemented the algorithm of active contour without edges (based Chan and Vese's paper) in Matlab at http://www.postulate.org/segmentation.php. It runs well, but is slow.

Another Matlab implementation is by Dr. Chunming Li (who is a collaborator of Dr. Kao) and is available at http://www.engr.uconn.edu/~cmli/code/. It is much faster and also has the implementation for multiple levelset functions.
