関数詳解

args()

template<typename... _Tps>

Kernel & cv::ocl::Kernel::args ( const _Tps &...  kernel_args )

inline

Setup OpenCL Kernel arguments. Avoid direct using of set(i, ...) methods.

bool ok = kernel
    .args(
        srcUMat, dstUMat,
        (float)some_float_param
    ).run(ndims, globalSize, localSize);
if (!ok) return false;

run()

bool cv::ocl::Kernel::run	(	int	dims,
		size_t	globalsize[],
		size_t	localsize[],
		bool	sync,
		const Queue &	q = Queue()
	)

Run the OpenCL kernel.

引数

dims	the work problem dimensions. It is the length of globalsize and localsize. It can be either 1, 2 or 3.
globalsize	work items for each dimension. It is not the final globalsize passed to OpenCL. Each dimension will be adjusted to the nearest integer divisible by the corresponding value in localsize. If localsize is NULL, it will still be adjusted depending on dims. The adjusted values are greater than or equal to the original values.
localsize	work-group size for each dimension.
sync	specify whether to wait for OpenCL computation to finish before return.
q	command queue

runProfiling()

int64 cv::ocl::Kernel::runProfiling	(	int	dims,
		size_t	globalsize[],
		size_t	localsize[],
		const Queue &	q = Queue()
	)

Similar to synchronized run() call with returning of kernel execution time Separate OpenCL command queue may be used (with CL_QUEUE_PROFILING_ENABLE)

戻り値

Execution time in nanoseconds or negative number on error
