Tom Stellard	42b1bd56cc	ocl: Move static oclMat variables into FarnebackOpticalFlow class Move some static functions into the FarnebackOpticalFlow class as well, so they can access these new class variables. oclMat objects cannot be declared statically, because their destructor depends on the statically defined __module variable from cl_context.cpp. Since statically defined variables in separate compilation units have an undefined destruction order there is always the possibility the __module will be destructed before an oclMat object, which results in a segfault.	10 years ago
Tom Stellard	ec335b7398	ocl: Fix crash during destruction of gauss_w_lut object in hog.cpp gauss_w_lut is a statically defined variable of type oclMat. The oclMat destructor calls openCLFree() which via getInitializationMutex() accesses the __module variable which has been statically defined in cl_context.cpp Since the destruction order of statically defined variables in different compilation units is undefined, it is possible that __module will be destructed before gauss_w_lut, which would result in a segfault when getInitializationMutex() is called while destructing gauss_w_lut. In order to avoid this issue, we need to make gauss_w_lut a private member of the HOGDescriptors class so we know it will be destroyed before __module.	10 years ago
Tom Stellard	8f3b876ee6	ocl: Change static variable order in cl_context.cpp to avoid crashes during destruction ContextImpl::currentContext contains a reference to one of the DeviceInfoImpl objects from: static std::vector<DeviceInfoImpl> global_devices; ContextImpl::currentContext is destroyed in the destructor for the statically defined object __module, and relies on its DeviceInfoImpl reference to query some hardware features while being destroyed. This means that we need to ensure that the global_devices vector is destroyed affter __module, otherwise ContextImpl::currentContext's DeviceInfoImpl reference will no longer be valid when __module is destroyed. Since these variables are all confined to a single compilation unit, they will be destruct from bottom to top, so we need to make sure that __module is the bottom definition so it can be destroyed first.	10 years ago
Tom Stellard	934394c5e2	ocl: Don't use 'inline' attribute on functions In C99 'inline' is not a hint to the compiler to inline the function, it is an attribute that affects the linkage of the function. 'inline' functions are required to have a definition in a different compiliation unit, so compilers are free to delete 'inline' functions if they want to. This issue can be seen in Clang when compiling at -O0. Clang will sometimes delete 'inline' functions which creates an invalid program. Issue 3746: http://code.opencv.org/issues/3746	10 years ago

krodyush	27c1bd2762	Improve ocl cvt_color performance for the following conversions: RGB<->BGR, RGB->Gray, RGB<->XYZ, RGB<->YCrCb, RGB<->YUV, and mRGBA<->RGBA. The improvement was done basically by processing more than 1 pixel by each work-item and using vector's operations. new performance tests were added	11 years ago
