◆ calc()

virtual void cv::cuda::DenseOpticalFlow::calc ( InputArray  I0,
InputArray  I1,
InputOutputArray  flow,
Stream stream = Stream::Null() 
)
pure virtual

Calculates a dense optical flow.

Parameters
I0first input image.
I1second input image of the same size and the same type as I0.
flowcomputed flow image that has the same size as I0 and type CV_32FC2.
streamStream for the asynchronous version.
