I am getting a different keypoint angle when I am trying to compute the same thing in 2 different ways:
1.
detectAndCompute(img1, noArray(), kpts1, noArray(), false);
detectAndCompute(img1, noArray(), kpts1, desc1, true);
2.
detectAndCompute(img1, noArray(), kpts1, desc1);
I am getting a difference only on the keypoint angle (not a significant), which makes also descriptors to be different.
I am using **KAZE** keypoint extractor (OpenCV 3.0.0)
Any help on this?
Thank you.
