WebORB is found to be least scale invariant. ORB(1000), BRISK(1000), and AKAZE are more rotation invariant than others. ORB and BRISK are generally more invariant to affine changes as compared to others. SIFT, KAZE, AKAZE, and BRISK have higher accuracy for image rotations as compared to the rest. Web8 de jan. de 2016 · Obviously, OpenCV flann module cannot decide what type you intend to use but can warn you if use the odd combination. Perhaps we can teach OpenCV to be more explicit in its errors with simple clear and comprehensible texts instead of "type=0", but this is another issue. hillcrest high school illinois website
