WebJan 8, 2013 · Optical flow is the pattern of apparent motion of image objects between two consecutive frames caused by the movement of object or camera. It is 2D vector field where each vector is a displacement vector showing the movement of points from first frame to second. Consider the image below (Image Courtesy: Wikipedia article on Optical Flow ). WebJan 8, 2013 · virtual int cv::cuda::OpticalFlowDual_TVL1::getNumWarps. (. ) const. pure virtual. Number of warpings per scale. Represents the number of times that I1 (x+u0) and grad ( I1 (x+u0) ) are computed per scale. This is a parameter that assures the stability of the method. It also affects the running time, so it is a compromise between speed and ...
