WebDec 27, 2024 · One way to improve disparity map results is by using a smoothing constraint, such as Semi-Global Matching(SGM) or Semi-Global Block Matching. Before, we picked the disparity for a pixel based on the minimum matching cost of the block using some metric(SSD or SAD). The basic idea of SGM is to penalize pixels with a disparity that’s very … WebMay 27, 2024 · OpenCV's "semi-global block matching" method; memory-intensive 2-pass version, which can only handle the quarter-size… vision.middlebury.edu For a little enhanced local method estimation ...
