Wrong xy order when sampling the correlation map
npmhung opened this issue · comments
When you construct the delta matrix here, the coordinate is actually in yx not xy order. However, it does not affect the final results because the sampling region is from -r to r in both x and y dimension. Therefore, the sampled correlation matrix is a transposed version of what it should be.
I just want to raise the issue in case anyone wants to actually use the coordinates to do something else that requires the order to be correct.
