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 ). WebSource code of the Robust Local Optical Flow is now available! We are happy that Robust Local Optical Flow is now part of the OpenCV Contribution GIT. Robust Local Optical Flow V1.3. This repository contains the RLOF library for Robust Local Optical Flow based motion estimation. The software implements several versions of the RLOF algorithm.
