ABSTRACT

The perception of motion can be separated into three categories: (1) the perception of objects moving relative to the observer, (2) the perception of the observer moving relative to objects in the environment, and (3) the perception of both motion of the observer and motion of objects. Considerable research has been conducted on the information and processing constraints used by the human visual system to perceive object motion or self-motion (see Andersen, 1986; Braunstein, 1976; and Dichgans & Brandt, 1978; for reviews). Other research by the artificial intelligence community has examined the sufficiency conditions for the recovery of 3-D structure or self-motion by any visual system.
