Vadim Pisarevsky 0c773ca931 updated ORB: limit the number of output keypoints, use bi-linear interpolation between subsequent layers instead of much slower area-based interpolation between 0-th and i-th layers. 2011-11-22 09:44:37 +00:00
Vadim Pisarevsky 2e9f5c434b added improved ORB implementation, convex-convex polygon intersection, eigen2x2 low-level function ... 2011-11-08 12:01:49 +00:00
