Jinay Patel	f710d96602	Update ocl.cpp function Device::OpenCLVersion() Instead of CL_DEVICE_EXTENSIONS in Querying OpenCLVersion, it should be CL_DEVICE_VERSION flag which needs to be passed to the function.	8 years ago
Fangjun KUANG	5e4dfb9546	Change the argument type to cl_platform_info. Although both `cl_platform_info` and `cl_device_info` are defined as macro `cl_uint`, it needs to use `cl_platform_info` to get the platform information.	8 years ago
Alexander Alekhin	4c7aa8645a	ocl: validate arguments in KernelArgs constructor - don't use undefined flag=0. It should be CONSTANT instead. - don't allow 'UMat* m=NULL' argument (except LOCAL/CONSTANT flags). This case is not handled well to provide NULL __global pointers. It is better to use '-D' macro defines instead (at least for performance)	8 years ago

Addison Elliott	eb04b2bfa9	Added N-dim submat selection with vectors Currently, to select a submatrix of a N-dimensional matrix, it requires two lines of code while only one line of code is required if using a 2D array. I added functionality to be able to select an N-dim submatrix using a vector list instead of a Range pointer. This allows initializer lists to be used for a one-line selection.	8 years ago
Addison Elliott	fa6692afcf	Added new overloaded functions for Mat and UMat that accepts std::vector<int> instead of int * for the sizes on a N-dimensional array. This allows for an N-dimensional array to be setup in one line instead of two when using C++11 initializer lists. cv::Mat(3, {zDim, yDim, xDim}, ...) can be used instead of having to create an int pointer to hold the size array.	8 years ago
