WebThe pattern of the motion of the image object from one frame to the consecutive due to camera’s movement or object’s movement is called optical flow. The optical flow is represented by two dimensional vector also called as displacement vector. The optical flow can be found out by implementing the Lucas Kanade algorithm.
