Elena Gvozdeva	6185f7209e	Merge pull request #10172 from ElenaGvozdeva:eg/HAL_sobel * add HAL for SobelFilter * add HAL for pyrDown * add HAL for Scharr	7 years ago
Alexander Alekhin	0ed3209b00	ocl: avoid unnecessary loading/initializing OpenCL subsystem If there are no OpenCL/UMat methods calls from application. OpenCL subsystem is initialized: - haveOpenCL() is called from application - useOpenCL() is called from application - access to OpenCL allocator: UMat is created (empty UMat is ignored) or UMat <-> Mat conversions are called Don't call OpenCL functions if OPENCV_OPENCL_RUNTIME=disabled (independent from OpenCL linkage type)	7 years ago
Pavel Vlasov	a57718e1ac	ICV2017u3 package update; - Optimizations set change. Now IPP integrations will provide code for SSE42, AVX2 and AVX512 (SKX) CPUs only. For HW below SSE42 IPP code is disabled. - Performance regressions fixes for IPP code paths; - cv::boxFilter integration improvement; - cv::filter2D integration improvement;	8 years ago

Li Peng	6cb73356b1	laplacian ocl kernel optimization This ocl kernel is 46%~171% faster than current laplacian 3x3 ocl kernel in the perf test, with image format "CV_8UC1". Signed-off-by: Li Peng <peng.li@intel.com>	8 years ago
Li Peng	8d4a7d3dcc	sobel and scharr ocl kernel optimization It improves 108%~230% performance in the perf test with image format "CV_8UC1" and kernel size 3. Signed-off-by: Li Peng <peng.li@intel.com>	8 years ago

Pavel Vlasov	e837d69f8f	IPPInitSingelton was added to contain IPP related global variables; OPENCV_IPP env var now allows to select IPP architecture level for IPP9+; IPP initialization logic was unified across modules;	10 years ago
Pavel Vlasov	62854dcc0d	Enables support of IPP 9.0.0; HAVE_IPP_ICV_ONLY will be undefined if OpenCV was linked against ICV packet from IPP9 or greater. ICV9+ packets will be aligned with IPP in OpenCV APIs This will ease code management between IPP and ICV	10 years ago
Pavel Vlasov	14b006e808	IPP_VERSION_X100 was changed to: IPP_VERSION_MAJOR * 100 + IPP_VERSION_MINOR*10 + IPP_VERSION_UPDATE to manage changes between updates more easily. IPP_DISABLE_BLOCK was added to ease tracking of disabled IPP functions;	10 years ago
