Methods

virtual
void
calc(
    InputArray I0,
    InputArray I1,
    InputOutputArray flow
    ) = 0

Calculates an optical flow.

Parameters:

I0	first 8-bit single-channel input image.
I1	second input image of the same size and the same type as prev.
flow	computed flow image that has the same size as prev and type CV_32FC2.

virtual
void
collectGarbage() = 0

Releases all inner buffers.
