I have been testing ocl/hog.cpp in my desktop with AMD Radeon HD 5700 Series using window7 64bit and visual studio 2012. But during executing, people detecting of GPU mode is not so good(very low detecting rate). In CPU mode (changed by m key), people detecting rate is good.
What should i do to get high detecting rate in GPU mode? Could you let me know how to improve detecting rate in GPU mode and show me the way in detail please?
Some information.. Both GPU and CPU mode is same parameters(scale, level number, threshold, etc...) and AMD GPU Device driver(AMP APP) is already install. As executing opencv_perf_ocld.exe, all of GPU performance is better than CPU's. GPU usage is checked. Also CMake is done and .dll file is made by solution build(OpenCV.sln)
