§ operator()()

void cv::gpu::BroxOpticalFlow::operator()	(	const GpuMat &	frame0,
		const GpuMat &	frame1,
		GpuMat &	u,
		GpuMat &	v,
		Stream &	stream = `Stream::Null()`
	)

Compute optical flow frame0 - source frame (supports only CV_32FC1 type) frame1 - frame to track (with the same size and type as frame0) u - flow horizontal component (along x axis) v - flow vertical component (along y axis)
