◆ calc()

virtual void cv::DenseOpticalFlow::calc ( InputArray  I0,
InputArray  I1,
InputOutputArray  flow 
pure virtual
cv.DenseOpticalFlow.calc(I0, I1, flow) -> flow

Calculates an optical flow.

I0first 8-bit single-channel input image.
I1second input image of the same size and the same type as prev.
flowcomputed flow image that has the same size as prev and type CV_32FC2.

Implemented in cv::optflow::OpticalFlowPCAFlow.

◆ collectGarbage()
