WebTheoretically, optical flow is the motion of visual features such as points, objects, and shapes through a continuous view of the environment. It represents the motion of the environment relative to an observer. James Jerome Gibson first introduced the optical flow concept in the 1940s, during World War II [ 24 ]. WebFeb 9, 2024 · Changes in the flow of the optic array contain important information about what type of movement is taking place. The flow of the optic array will either move from or towards a particular point. If the flow appears to be coming from the point, it means you are moving towards it. If the optic array is moving towards the point, you are moving ...
