Vadim Pisarevsky	07b475062f	Merge pull request #16608 from vpisarev:fix_mac_ocl_tests * fixed several problems when running tests on Mac: * OCL_pyrUp * OCL_flip * some basic UMat tests * histogram badarg test (out of range access) * retained the storepix fix in ocl_flip only for 16U/16S datatype, where the OpenCL compiler on Mac generates incorrect code * moved deletion of ACCESS_FAST flag to non-SVM branch (where SVM is shared virtual memory (in OpenCL 2.x), not support vector machine) * force OpenCL to use read/write for GPU<=>CPU memory transfers on machines with discrete video only on Macs. On Windows/Linux the drivers are seemingly smart enough to implement map/unmap properly (and maybe more efficiently than explicit read/write)	5 years ago
Ciprian Alexandru Pitis	d2e02779c4	Merge pull request #15799 from Cpitis:feature/parallelization Parallelize pyrDown & calcSharrDeriv * ::pyrDown has been parallelized * CalcSharrDeriv parallelized * Fixed whitespace * Set granularity based on amount of threads enabled * Granularity changed to cv::getNumThreads, now each thread should receive 1/n sized stripes * imgproc: move PyrDownInvoker<CastOp>::operator() implementation * imgproc(pyramid): remove syloopboundary() * video: SharrDerivInvoker replace 'Mat*' => 'Mat&' fields	5 years ago
