I noticed that you obtained the number of corner points through detectFASTFeatures. I wanted to achieve uniform distribution of feature points in the SAR-SIFT algorithm, so I made some modifications. I did not fix the number of numRetPoints and set it to the number of initial feature points, and then set tolerance to 0.1. As a result, the MEX file showed an unexpected standard exception during debugging. What() is: bad allocation . .

Error gsar_sift (line 102) selectedIdx1 = SSC(double(corners1.Location(ind1,:)), numRetPoints_1, tolerance, size(image_11,2), size(image_11,1));
