Class ORB

Namespace
OpenCvSharp
Assembly
OpenCvSharp.dll

Class implementing the ORB (oriented BRIEF) keypoint detector and descriptor extractor.

described in @cite RRKB11 . The algorithm uses FAST in pyramids to detect stable keypoints, selects the strongest features using FAST or Harris response, finds their orientation using first-order moments and computes the descriptors using BRIEF (where the coordinates of random point pairs (or k-tuples) are rotated according to the measured orientation).
