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. I'm using ORB feature detector and and Flann matcher. To use the matcher I compute keypoints and descriptors for the first image (img1) and then for each picture from the set, run the flann matcher comparing each of the images with img1 and get the best result.

Web13 de nov. de 2015 · I managed to temporarily fix this for my simple project by downgrading from openCV 3.1 to openCV 2.4. Have you found a fix to this other than downgrading? I am new to not only openCV but also to python. I am using python 2.7.11, numpy 1.10.2 superpack for python 2.7, scipy 0.16.1 superpack for python 2.7, and openCV 3.1.

As long as the keypoint orientation is consistent across views, the correct set of points will be used to compute its descriptor. BRIEF has an important property that each bit feature has a large variance and a mean … ford recall for rear camera
