Vitaly Tuzov	51cb56ef2c	Implementation of bit-exact resize. Internal calls to linear resize updated to use bit-exact version. (#9468 )	7 years ago
Vadim Pisarevsky	5ce38e516e	Merge pull request #10223 from vpisarev:ocl_mac_fixes * fixed OpenCL functions on Mac, so that the tests pass * fixed compile warnings; temporarily disabled OCL branch of TV L1 optical flow on mac * fixed other few warnings on macos	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

LukeZhu	65be9e1978	Fix OpenCL's wrong output of calcOpticalFlowPyrLK function's output vector of err. Improve err's precison of the calcOpticalFlowPyrLK OpenCL function and add the relative test.	8 years ago
Michele Cancilla	9405c6d206	Improvement of array of equivalences’ upper bound + fix some wrong comments	8 years ago
Fernando Iglesias Garcia	21e698053f	Initialize background model in background subtraction KNN. The method does cvCheckPixelBackgroundNP (which reads bgmodel) before it is ever updated (in cvUpdatePixelBackgroundNP). This initialization is thus needed to avoid reads of unitialized values.	8 years ago

Gilles Rochefort	9e53f03968	Fixed BackgroundSubstractorMOG2 in opencv_video. The number of gaussians involved in a mixture is supposed to be dynamically adjusted. After being increased, the number of gaussians can't be reduced anymore. It seems to be a regression as the legacy code located in modules/legacy/src/bgfg_gaussmix.cpp allows to reduce such number of gaussians.	9 years ago
