Can someone send me a source code for window-based stereo matching algorithm

Hi
    I am new to stereo vision, currently I am doing a project on stereo matching for a given pair of rectified stereo images and try to get depth map as output. There are so many algorithms in this area, and I have to start to learn from the most basic one, the window-based stereo matching algorithm.

    I have read the paper A Window-based Stereoscopic System Using A Weighted Average of Costs Aggregated with Window Size Reduction, but not able to implement it in c++.  Does anyone know where i can download source code for this algorithm?
Thank you

Regards,
Weimin

Trying to find source code online for a paper you read is usually impossible. Unless the paper mentions a location where you can find it, it probably isn't out there.
However, if you email the authors and tell them what you are doing (writing a survey paper is a good reason), they will likely send you what they used for their simulations. Make sure to ask how they would like their work cited (everyone likes a good citation). That will encourage them to assist you.

Their paper says they did their simulation in C++. You can't usually be picky about language, but it looks like you lucked out.

Dear aburr and TommySzalapski:

    Thank you for your reply!

For aburr:
     I really appreciate your help. But unfortunately, it is not what I really need. I need a window-based stereo matching algorithm code which is the basic one in stereo matching field. Because I just started to learn stereo matching, and window-based is the one that I can handle, and just wanna see how it can be implemented. ( am not quite good at c++, so not able to implement it myself)

For TommySzalapski:
    I have contacted two authors of the paper before I post question here, but it seems that there is no responding so far from them. And I have just emailed the other two authors of the paper in your way, and see if they will reply me. Will let you know soon.

Again, my question is that I need a source code for window-based stereo matching algorithm, and better to be the implementation of paper: A Window-based Stereoscopic System Using A Weighted Average of Costs Aggregated with Window Size Reduction
More answers are encouraged!

Have you tried implementing it yourself? Perhaps we could help you do that in case they still don't answer. What do you have so far?

Hi TommySzalapski:

       There is still no reply from them. What I have now is only copy of their research paper. I understand the paper but can not implement it because I am quite new in C++. It would be much appreciated if you can help me on this. Sorry for the reply delay due to time zone.

Regards,
Weimin

Since you already understand the paper (I hope) and since it's your project, can you write up a psuedo-code attempt? We'll help you get it working.
