WebNov 12, 2024 · Optical Flow Estimation. Advancements in optical flow estimation techniques largely rely on the success of data-driven deep learning frameworks. Flownet marked one of the initial adoption of CNN- based deep learning frameworks for optical flow estimation. 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.
