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
Li Peng	8f63f51e81	gaussian blur ocl kernel optimization This ocl kernel is for 3x3 kernel size and CV_8UC1 format It is 115% ~ 300% faster than current ocl path in perf test python ./modules/ts/misc/run.py -t imgproc --gtest_filter=OCL_GaussianBlurFixture* Signed-off-by: Li Peng <peng.li@intel.com>	8 years ago
Li Peng	35198b84a4	morph ocl kernel for erode and dilate filter This kernel is for CV_8UC1 format and 3x3 kernel size, It is about 33% ~ 55% faster than current ocl kernel with below perf test python ./modules/ts/misc/run.py -t imgproc --gtest_filter=OCL_ErodeFixture* python ./modules/ts/misc/run.py -t imgproc --gtest_filter=OCL_DilateFixture* Also add accuracy test cases for this kernel, the test command is ./bin/opencv_test_imgproc --gtest_filter=OCL_Filter/MorphFilter3x3* Signed-off-by: Li Peng <peng.li@intel.com>	8 years ago
Li Peng	3607da9f6b	ocl kernel performance optimization for box filter The optimization is for CV_8UC1 format and 3x3 box filter, it is 15%~87% faster than current ocl kernel with below perf test ./modules/ts/misc/run.py -t imgproc --gtest_filter=OCL_BlurFixture* Also add test cases for this ocl kernel.
