Member Function Documentation

◆ calc()

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

Calculates an optical flow.

Parameters
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()

virtual void cv::DenseOpticalFlow::collectGarbage ( )
pure virtual
Python:
None=cv.DenseOpticalFlow.collectGarbage()

Releases all inner buffers.

Implemented in cv::optflow::OpticalFlowPCAFlow.
