We are very glad that the post was helpful. ArrayFire functions for computer vision algorithms are currently under testing phase. We very recently did a blog post on feature detection which can be found at http://sandbox.arrayfire.com/computer-vision-arrayfire-part-1/ . In this post, we shared the benchmarks of Harris corner detector and FAST feature detector in comparision with OpenCV's implementation. We shall keep posting new benchmarks as more functions pass through the testing phase.
