Depth map from stereo pair

Hi:

 

I am a bit late to the party but I may have some answers for you.

 

There are basically 3 schools of thought regarding stereo matching aka depth map creation from a stereo pair:

1) local method based on window/patch/block correlation

2) global methods like graph cuts

3) variational methods like optical flow

 

there's no magic method though that works 100% of the time. more often that not, the depth map will have quite a bit of noise depending on how much smoothing has been applied.

 

I have implemented a fair number of automatic depth map generators that you can try them at:

 

3D software for depth map creation

 

the best part is that it's all free to download and use.
