- Parameters
-
radiusList defines the radii (in pixels) where the samples around a keypoint are taken (for keypoint scale 1).
numberList defines the number of sampling points on the sampling circle. Must be the same size as radiusList..
dMax threshold for the short pairings used for descriptor formation (in pixels for keypoint scale 1).
dMin threshold for the long pairings used for orientation determination (in pixels for keypoint scale 1).
indexChange index remapping of the bits.
