Member Function Documentation#

calc()#

void cv::cuda::DenseOpticalFlow::calc(
InputArray I0,
InputArray I1,
InputOutputArray flow,
Stream & stream = Stream::Null() )

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.
