John, do you know how to use the debugger? Because that is your best approach. If not, look here: http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/. Second best approach is to ask "Author: Baris Sumengen sumengen@ece.ucsb.edu" for help since he gave you the code. He might be willing to help you even more to get it working. That's a lot of code to ask us to dig into, understand, fix, and hand over to you to resolve the vague problem that "the solution is never what ti should be."

MATLAB has an active contour function built in. If you want me to give you my demo, let me know.
