Alexander Alekhin	f21f153a5f	test: backport check for Image_KernelSize_GaborFilter2d perf test	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
k-shinotsuka	cf5c400ecb	add SSE code for RGB2HLS_f.	8 years ago
Juha Reunanen	5bb08bae28	Merge pull request #7464 from reunanen:test-7409-7458 Change contour test images to be very wide (#7464) * Change contour test images to be very wide (#7409, #7458) Unfortunately, slows down the tests. * Decrease the number of contour test cases, in order to (at least partially) offset the test run duration increase caused by making the test images wider * Don't test with very wide images on 32-bit architectures	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 Rojtberg	3609343acf	undistortPoints: only consider distCoeffs if present iters should be 0 if we have no distortion. Also skip tilt distortion in that case. Furthermore move variable declarations to usage sites.	8 years ago

Pavel Vlasov	349d5ba012	--perf_instrument parameter now has int type and 0, 1, 2 modes (1 - simple trees, 2 - expanded trees for functions with same name but different calling address); Maximum depth limit var was added to the instrumentation structure; Trace names output console output fix: improper tree formatting could happen; Output in case of error was added; Custom regions improvements; Improved timing and weight calculation for parallel regions; New TC (threads counter) value to indicate how many different threads accessed particular node; parallel_for, warnings fixes and ReturnAddress code from Alexander Alekhin;	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
