WitrynaOriented FAST and Rotated BRIEF ( ORB) was developed at OpenCV labs by Ethan Rublee, Vincent Rabaud, Kurt Konolige, and Gary R. Bradski in 2011, as an efficient and viable alternative to SIFT and SURF. ORB was conceived mainly because SIFT and SURF are patented algorithms. ORB, however, is free to use. WitrynaORB is the abbreviation of Oriented Fast and Rotated Brief. It can be used to quickly create feature vectors for key points in the image. These feature vectors can be used to identify objects in the image. The ORB feature is a combination of the FAST feature point detection method and the BRIEF feature descriptor, and has been improved and ...
