Member Function Documentation#

calc()#

void cv::DenseOpticalFlow::calc(
InputArray I0,
InputArray I1,
InputOutputArray flow )

Python:

cv.DenseOpticalFlow.calc(I0, I1, flow) -> flow

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.

collectGarbage()#

void cv::DenseOpticalFlow::collectGarbage()

Python:

cv.DenseOpticalFlow.collectGarbage()

Releases all inner buffers.
