yao	6db776f957	add "-c" for cpu ocl mode in perf tests	12 years ago
peng xiao	290c8db0a8	Revise naming for getOclMat function.	12 years ago
peng xiao	e129638263	Add a workaround to interpolate between oclMat and Input/OutputArray.	12 years ago
peng xiao	c1f4fe1637	Fix a bug of convertTo. The bug was found that all 3-channel oclMat's were converted to 4-channel oclMat's after using convertTo function.	12 years ago
Roman Donchenko	1ed5fb937d	Give cv::ocl::CLAHE a virtual destructor, for the usual reasons.	12 years ago
yao	2c198f6cd6	revise accuracy and perf tests	12 years ago
yao	26c246140a	optimize hog	12 years ago
peng xiao	e6b18fc492	Fix a bug caused by NDEBUG macro; it is now removed. Revise some descriptions of the enums.	12 years ago
peng xiao	5fd724b54a	Add a function to query if global OpenCL context is initialized.	12 years ago
Peng Xiao	d9ab22e4ed	Fix two bugs related to opencl context. 1. As getDevice will implicitly call setDevice, in getContext we should not need to call it again. 2. Fix an incorrect type casting.	12 years ago
Peng Xiao	c8398c9fdc	Use anonymous enumerations instead of constants	12 years ago
Peng Xiao	1d8cd3a717	Add ocl CLACH implementation. Test cases (accuracy and performance) are provided.	12 years ago
Peng Xiao	e77abeef16	Add a new global function to control ocl binary storage Previously the feature is controlled by setBinpath implicitly. We add the function to cope with setBinpath and setBinpath is only useful when setBinaryDiskCache is set. Refer to the header to see more info.	12 years ago
peng xiao	429f84e59e	Fix a bug of cornerHarris and cornerMinEigenVal. The bug is a buffer overrun when border type is reflect101. It is found that gfft crashed with input of size 100x100 on Intel CPU.	12 years ago
peng xiao	a7a94de74a	Fix a bug of gfft. When user provided corners buffer is big enough to be copied to from tmpCorners_, we allow the buffer to be reused other than allocate a new cl_mem object.	12 years ago
yao	dc937c10f9	change a test image of pyrlk	12 years ago
peng xiao	97b86aa259	Initialize OpenCL context at the end of getDevice call. Added for better compatibility with the current samples/test cases. User now will be able to initialize OpenCL context explicitly with ocl::getDevice api. This may be obsoleted in future releases.	12 years ago
yao	15a213d3fc	fix a crash on Linux	12 years ago
yao	abefcc6061	Adjust perf_filters, as this function only supports 3x3 kernel	12 years ago
peng xiao	b1c248fcc9	Fix ocl::filter2D. In current implementation, this function only works when anchor point is in the kernel center and kernel size supported is either 3x3 or 5x5.	12 years ago
peng xiao	fdc133d8c9	Fix ocl::pyrup kernel build on Mac.	12 years ago
yao	5b598f8a0e	a few fixes of ocl::perf test cases	12 years ago
yao	7ed9c0e87a	Fix brute_force_matcher's hung on some Intel CPU OCL	12 years ago
peng xiao	fd7ba355ee	Add non-stump based ocl Haar cascade classifier support. For example, haarcascade_frontalface_alt2.xml is now supported. Note that classifier's pattern of a cascade file must be consistent, i.e., all trees must either have two nodes or one node, otherwise unexpected results will occur. Other fixes: Test cases are updated. Some unused codes are removed. Fix some problems of haar when using OclCascadeClassifierBuf.	12 years ago
yao	a9b7ff41bd	adjust test cases	12 years ago
peng xiao	d015fa76fa	Fix 2.4 ocl Canny. This fix is a workaround for current 2.4 branch without introducing an additional oclMat buffer into CannyBuf object. Test case is cleaned up. Volatile keywords in kernels are removed for performance concern.	12 years ago
yao	d81c145fa9	fix memory leak	12 years ago
yao	14bd6402be	revise perf	12 years ago
peng xiao	1d0c283508	Fix a bug when pushing pointers of arguments into std::vector. When argument pointers pushed into an vector and the pointers point to address on stack, we need to make sure they are valid until kernels are successfully flushed onto the queue.	12 years ago
peng xiao	6fae02c05d	Fix some OpenCL kernel file build errors on Mac.	12 years ago
yao	c58e0d5d73	fix hog	12 years ago
yao	d45f9ef866	fix Linux build errors	12 years ago
yao	a223b5624f	fix pyrLK's mismatch on Intel GPUs	12 years ago
Jan Machacek	46b770f255	Fixed include name in OpenCL on OS X	12 years ago
peng xiao	b4a4a05bdc	Add ocl's good features to track implementation. Additional notes with this commit: 1. Add cornerHarris_dxdy and cornerMinEigenVal_dxdy to get the interim dx and dy output of Sobel operator; 2. Add minMax_buf to allow user to reuse buffers in minMax; 3. Fix an error when either min or max pointer fed into minMax is NULL; 4. Corner sorter temporarily uses C++ STL's quick sort. A parallel selection sort in OpneCL is contained in the implementation but disabled due to poor performance at the moment. 5. Accuracy test for ocl gfft.	12 years ago
yao	d8b192c84d	Fix the mismatch on NV GPUs	12 years ago

yao	5f20fce6fd	add accuracy tests while running perf	12 years ago
peng xiao	d053f2165d	Add BFMatcher_OCL class alias for BruteForceMatcher_OCL. This adds a similar interface with pure-cpp and gpu versions.	12 years ago
peng xiao	3f93c3cc4e	Clean up spaces in ocl.hpp	12 years ago
peng xiao	df3997b108	Fix ocl::pyrUp Use predefined OpenCL function to convert integers to floating points. This is more accurate than before as it enables: 1. saturate cast 2. customized rounding	12 years ago
yao	1d1d28baf2	fix black screen when input Mat is large	12 years ago
peng xiao	ac21cabda2	Copy ocl::queryDeviceInfo interface from master to 2.4. Affected functions surf.ocl, pyrlk.ocl and hog.ocl are updated with the change.	12 years ago

yao	ada8f92cc7	fix warnings, unify test names	12 years ago
peng xiao	e14acabb3d	Fix ocl moudle build with latest Intel OpenCL SDK. We found that cl.h file provided in latest Intel SDK muted deprecated interfaces.	12 years ago
