Hello, I'm using SurfFeatureDetector along with SurfDescriptorExtractor and FlannBasedMatcherto align images. I tried to replace SurfFeatureDetector with gpu::SURF_GPU
I was expecting performance improvements, but the processing time stays almost same (within 5%) My GPU is Quadro K2000 2GB and CPU is Xeon E5-1650 v2 @3.5GHz
I have same situation (almost no improvement in speed) in Remap and gpu::Remap I'm not counting first run of GPU function in timing
Is there a way to make GPU processing faster?
I'm using OpenCV 2.4.9 compiled with VS2012 and CUDA 6.0
