I use OpenCV2.4.11 + CUDA 7.5 + GeForece GTX 750 Ti. Source image for gpu::matchTemplate is large. I've done a comparison between GpuMat different sizes and i found best GpuMat size for gpu::matchtemplate in all six matching algorithm (CV_TM_SQDIFF .. CV_TM_CCOEFF_NORMED) and that is 9000*6000 (rows*cols).
I have two question:
1) How can i use of gpu::matchtemplate on largest images?
2) How to work gpu::MatchTemplateBuf?
