Method	Description
CreateContinuous ( Size size, MatType type ) : GpuMat	Creates continuous GPU matrix
CreateContinuous ( int rows, int cols, MatType type ) : GpuMat	Creates continuous GPU matrix
CreateContinuous ( Size size, MatType type, GpuMat m ) : void	Creates continuous GPU matrix
CreateContinuous ( int rows, int cols, MatType type, GpuMat m ) : void	Creates continuous GPU matrix
EnsureSizeIsEnough ( Size size, MatType type, GpuMat m ) : void	Ensures that size of the given matrix is not less than (rows, cols) size and matrix type is match specified one too
EnsureSizeIsEnough ( int rows, int cols, MatType type, GpuMat m ) : void	Ensures that size of the given matrix is not less than (rows, cols) size and matrix type is match specified one too
GetCudaEnabledDeviceCount ( ) : int	Returns the number of installed CUDA-enabled devices. Use this function before any other GPU functions calls. If OpenCV is compiled without GPU support, this function returns 0.
GetDevice ( ) : int	Returns the current device index set by SetDevice() or initialized by default.
PrintCudaDeviceInfo ( int device ) : void
PrintShortCudaDeviceInfo ( int device ) : void
RegisterPageLocked ( Mat m ) : void	Page-locks the matrix m memory and maps it for the device(s)
ResetDevice ( ) : void	Explicitly destroys and cleans up all resources associated with the current device in the current process. Any subsequent API call to this device will reinitialize the device.
SetDevice ( int device ) : int	Sets a device and initializes it for the current thread.
ThrowIfGpuNotAvailable ( ) : void
UnregisterPageLocked ( Mat m ) : void	Unmaps the memory of matrix m, and makes it pageable again.
