Hi,

I want to generate contours from image based on several values (tressholds in A, B, C....). So far, I am using Marching Squares, which works fine. Now for the problem. If I use MATLAB "contourc" function, I got far better results. My main problem is with duplicite contours.
Is there any better and still easy to implement algorithm besides Marching Squares ? And If anonyo knew, what MATLAB is using...

Thanks

I alreday read documentation for contourc. From that, it seems like similar aproach to marching squares. Hovewer, their algorithm doesn´t generate too much nested contours and has less contours for image while maintaining almost same visual as my Marching Squares.
