OpenCV FREAK: Fast Retina KeyPoint descriptor
问题 I am developing an application which involves the use of Freak descriptors, just released in the OpenCV2.4.2 version. In the documentation only two functions appear: The class constructor A confusing method selectPairs() I want to use my own detector and then call the FREAK descriptor passing the keypoints detected but I don't understand clearly how the class works. Question: Do I strictly need to use selectPairs() ? Is it enough just by calling FREAK.compute() ? I don't really understand
