I am using OpenCV 3.0 with VS2012 C++/CLI on a Win 8.1 64 bit machine.
I am using SURF to detect keypoints in full HD webcam images and am experimenting with both the GPU version and non-GPU version of SURF. One thing I notice is that the GPU version is finding about 20% fewer keypoints than the non-GPU version.
Is this something that others have seen? Is it expected?
Thanks, James
