WebOptical Flow: Techniques and Applications Optical Flow: Techniques and Applications Peter O’Donovan 502425 The University of Saskatchewan⁄ April 6, 2005 ⁄[email protected] 1 1 Introduction The analysis of sequence of images, used to approximate motion, is a core area of computer vision. Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and a scene. Optical flow can also be defined as the distribution of apparent velocities of movement of brightness pattern in an image.

WebThe first step in motion perception is for the visual system to estimate optical flow from the changing pattern of light in the retinal image. Then, the 3D motions of observer and objects can be inferred from the optical flow. The optic flow then provides information about the observer's heading and the relative distance to each surface in the ... 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.
