WebOptical flow is the apparent motion of brightness patterns in the image. Generally, optical flow corresponds to the motion field, but not always. For example, the motion field and optical flow of a rotating barber's pole are different, as illustrated in figure 3. WebFeb 8, 2024 · Optical flow is the pattern of the apparent motion of objects in a visual scene caused by the motion of an object or camera or both. When a camera records a scene for a given time, the resulting image sequence can be considered as a function of gray values at image pixel position (x,y) and the time t.
