Chuanbo Weng	2b52bb092a	Update hog.cpp ... Update according to vbystricky's comments	10 years ago
Chuanbo Weng	7452eef6e9	Correctly enable OpenCL mode in tapi's hog example. ... For current OpenCV-CL architecture, if the data buffer allocated in UMat are cpu buffer(not ocl buffer) under cpu mode, and then pass this UMat to an OpenCL kernel as an argument, the OpenCL path will fail and fallback to cpu mode. Take HOGDescriptor::oclSvmDetector as an example: ocl::setUseOpenCL(false); //data allocated in hog.oclSvmDetector will be cpu buffer hog.setSVMDetector(HOGDescriptor::getDaimlerPeopleDetector()); ocl::setUseOpenCL(true); //We enabled OpenCL, but hog.oclSvmDetector are cpu buffer, //so it will fail in the function ocl_classify_hists //when reach to this line //idx = k.set(idx, ocl::KernelArg::PtrReadOnly(detector)); hog.detectMultiScale(img, found, hit_threshold, win_stride, Size(0, 0), scale, gr_threshold); Similar problems heppen on img_aux and img. So we should re-define or re-set these UMat when do mode switch (CPU -> OpenCL) in order to make their data be allocated by ocl and then OpenCL path will succeed.
