Anyway, thank you very much.
It is worth mentioning that my question comes from the semi-global matching algorithm in stereo matching, which may be of interest to you. This is a very common algorithm in stereo vision.
I also found a problem when designing a stereo matching algorithm. When a design contains a large number of operators (for example, several thousand operators, which is common when the disparity level of stereo matching is 128 or greater), VisualApplets will becomes very stuck or even exits abnormally. Is this a known problem?
