can i make a logical of a matrix the same size as a matrix?

I have a matrix of doubles and convert the image to a black and whit image, anything in the whit is the inside the rest is outside.

I want to use logical to find the pixels of value 1 and use them to find the inner points of the curve.

is this possible?

thanks!

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 [e-mail]" 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.

Have you seen the Image Processing Toolbox's activecontour?

It has a Chan-Vese method already implemented

Either way, you're using someone else's function so what difference does it make?
