Open CV feature detection in GPU

Question

I'm using OpenCV 2.4.6 in a prototype of object detection and I was wondering in how to improve the feature detection/extraction performance. Someone knows if is it possible to run feature detection/extraction/matching, like SIFT/SIFT/BF, or even the findHomography, on GPU?

Tks

Answer 1

OpenCV GPU module contains implementations for FAST, ORB and SURF feature detectors/extractors and for BruteForceMatcher.

You can read more in documentation: http://docs.opencv.org/2.4.6/modules/gpu/doc/feature_detection_and_description.html http://docs.opencv.org/2.4.6/modules/nonfree/doc/feature_detection.html#gpu-surf-gpu
