1 BRIEF (Binary Robust Independent Elementary Features) {#tutorial_py_brief}8 - We will see the basics of BRIEF algorithm27 BRIEF comes into picture at this moment. It provides a shortcut to find the binary strings directly38 One important point is that BRIEF is a feature descriptor, it doesn't provide any method to find the40 recommends to use CenSurE which is a fast detector and BRIEF works even slightly better for CenSurE43 In short, BRIEF is a faster method feature descriptor calculation and matching. It also provides46 BRIEF in OpenCV49 Below code shows the computation of BRIEF descriptors with the help of CenSurE detector.

1 ORB (Oriented FAST and Rotated BRIEF) {#tutorial_py_orb}19 ORB is basically a fusion of FAST keypoint detector and BRIEF descriptor with many modifications to30 Now for descriptors, ORB use BRIEF descriptors. But we have already seen that BRIEF performs poorly31 with rotation. So what ORB does is to "steer" BRIEF according to the orientation of keypoints. For37 precomputed BRIEF patterns. As long as the keypoint orientation \f$\theta\f$ is consistent across v…40 BRIEF has an important property that each bit feature has a large variance and a mean near 0.5. But59 decides number of points that produce each element of the oriented BRIEF descriptor. By default it61 If WTA_K is 3 or 4, which takes 3 or 4 points to produce BRIEF descriptor, then matching distance
