title: Open CV feature detection in GPU
body: <p>I'm using <strong>OpenCV 2.4.6</strong> 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 <strong>GPU</strong>?</p>
