hi,Sehyung Lee.I have a question,when I run "run_matching.m"(as your parameters in paper),now I get 194 left_disparity_map about tain set.then compare with the ground truth ,I get the noc err is 6.5%,occ err is 8.3%.I don't know why , because your result should be interpolated then compare with the ground truth or other?Besides,I watch from your paper,first ,I think the disparity is dense by your method?why the disparity is sparse?99.33% in test.second,why don't use the max disparty is 256 as the kitti dekit recommend.please answer me ,thank you very much .

Thanks for the comment. I'll add an explanation about the role of each parameter as soon as possible in "run_matching" script.

Indeed more robust than other methods in many cases. But the "run_mataching" script is poorly commented - it would be nice if there would be a short description of what each parameter means, and the units used.
