Optical Flow

The concept of optical flow was introduced through the American psychologist James Gibson in the 1940s to go into detail the visual stimulus offered to animals moving over the world. Gibson stressed the importance of optic flow with regard to affordance perception, the power to discern possibilities for action inside environment. Optical flow is the pattern of apparent action of objects, surfaces, and edges inside a visual scene caused through the relative motion between an observer as well as the scene.
