The instantaneous positional relative velocity field of a scene projected onto an imaginary surface: a retinal velocity map. Mathematical analysis has shown that from a monocular view of a rigid, textured, curved surface it is possible to determine the gradient of the surface at any point and the motion relative to that surface from the velocity field of the changing retinal image and its first and second spatial derivatives. See Intrinsic Images.
