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 ...
