Tomoaki Teshima	3cbe60cca2	Merge pull request #9753 from tomoaki0705:universalMatmul * add accuracy test and performance check for matmul * add performance tests for transform and dotProduct * add test Core_TransformLargeTest for 8u version of transform * remove raw SSE2/NEON implementation from matmul.cpp * use universal intrinsic instead of raw intrinsic * remove unused templated function * add v_matmuladd which multiply 3x3 matrix and add 3x1 vector * add v_rotate_left/right in universal intrinsic * suppress intrinsic on some function and platform * add pure SW implementation of new universal intrinsics * add test for new universal intrinsics * core: prevent memory access after the end of buffer * fix perf tests	7 years ago
Alexander Alekhin	734ea77c9a	ocl(macosx): fix CL_INVALID_BUILD_OPTIONS for gemm programs MacOSX OpenCL compiler is very strict to whitespace issues	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

insoow	2922738b6d	Merge pull request #8104 from insoow:master Gemm kernels for Intel GPU (#8104) * Fix an issue with Kernel object reset release when consecutive Kernel::run calls Kernel::run launch OCL gpu kernels and set a event callback function to decreate the ref count of UMat or remove UMat when the lauched workloads are completed. However, for some OCL kernels requires multiple call of Kernel::run function with some kernel parameter changes (e.g., input and output buffer offset) to get the final computation result. In the case, the current implementation requires unnecessary synchronization and cleanupMat. This fix requires the user to specify whether there will be more work or not. If there is no remaining computation, the Kernel::run will reset the kernel object Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * GEMM kernel optimization for Intel GEN The optimized kernels uses cl_intel_subgroups extension for better performance. Note: This optimized kernels will be part of ISAAC in a code generation way under MIT license. Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * Fix API compatibility error This patch fixes a OCV API compatibility error. The error was reported due to the interface changes of Kernel::run. To resolve the issue, An overloaded function of Kernel::run is added. It take a flag indicating whether there are more work to be done with the kernel object without releasing resources related to it. Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * Renaming intel_gpu_gemm.cpp to intel_gpu_gemm.inl.hpp Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * Revert "Fix API compatibility error" This reverts commit `2ef427db91`. Conflicts: modules/core/src/intel_gpu_gemm.inl.hpp * Revert "Fix an issue with Kernel object reset release when consecutive Kernel::run calls" This reverts commit `cc7f9f5469`. * Fix the case of uninitialization D When C is null and beta is non-zero, D is used without initialization. This resloves the issue Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * fix potential output error due to 0 * nan Signed-off-by: Woo, Insoo <insoo.woo@intel.com> * whitespace fix, eliminate non-ASCII symbols * fix build warning	8 years ago

Benjamin Flesch	62533d0d26	perspectiveTransform simplify assert() for better debuggin When using perspectiveTransform in rather complicated settings, it would be easier for developers to have two separate assertions for each part of the boolean expression in order to pinpoint problems more efficiently. In my case I am struggling in Python2.7 with finding out whether scn+1 == m.cols or the depth == CV_32F \|\| depth == CV_64F is making a problem, which is kind of hard.	11 years ago
