WebOct 12, 2024 · Optical Flow can be defined as a pattern of motion of pixels between two consecutive frames. The motion can be caused either by the movement of a scene or by the movement of the camera. The main idea behind Optical Flow is to estimate the object’s displacement vector caused by its motion or camera movements method components.
