I don't understand why this code generates a ridicilous result...

I'm trying to write a permeability filter given in the paper: http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=6130315&tag=1 (Efficient Edge-Preserving Stereo Matching)

The thing is, I just want to filter an image using the idea presented in the paper. Just to have a smoothed but edge pronounced image. But I don't want to apply stereo vision procedures.

Here is my code, http://me.metu.edu.tr/people/kemal/mv.rar.

I don't know if this kind of questions are allowed or not, but I don't have a choice, so I ask anyway. I couldn't find the bug in my code. This may be due to the fact that, I migrated from C/C++ to MATLAB. So, maybe I confuse the codes because they are similar.

You could hire a consultant. I very much doubt that anyone in this forum is willing to do your work for you. People, on the other hand, are more than happy to help you along, provided you ask specific Matlab questions.

It is very unlikely that a question of the type: "Please read this paper and code this algorithm for me" will ever be answered. You could check in the file exchange if this has been done before.
