§ 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)
