How about the second highest orientation? #3

Thanks for sharing the repository!

When I read the code,I found that there is only the main angle used in the function “calc_sift_descriptor.m”. Do you have any plan in the future how to use the second highest orientation? Although only about 15% of points are assigned multiple orientations, but these contribute significantly to the stability of matching.

Thanks again!

Thank you very much for your questions. We have assigned one or more orientations for each keypoint in the function "find_scale_space_extream".
