Methods

virtual
void
calc(
    InputArray I0,
    InputArray I1,
    InputOutputArray flow,
    Stream& stream = Stream::Null()
    ) = 0

Calculates a dense optical flow.

Parameters:

I0	first input image.
I1	second input image of the same size and the same type as I0.
flow	computed flow image that has the same size as I0 and type CV_32FC2.
stream	Stream for the asynchronous version.
