How does stereo SGBM algorithm really work inside ? Hello everyone, I have been playing with stereo BM & stereo SGB

Thanks to michaelr, I have been able to understand the first of my questions. Anyone able to help for the other question

Thank you for your reply! It is very helpful. Have you any idea of how to explain the "directions" that can be used (3,

How does stereo SGBM algorithm really work inside ? Hello everyone, I have been playing with stereo BM & stereo SGB

Well I checked and this is what I understood : the window size seems to be for connected component as you suggested, and

Thank you, I will check for the window size. Also, what did you mean by "disagree with neighboring pixels"?
