Vision as an anticipatory process

Vision is a crucial sensor. It provides a very rich collection of information about our environment. The difficulty in vision arises, since this information is not obvious in the image, it has to be constructed. Wheres earlier approaches have favored a bottom-up approach, which maps the image onto an internal representation of the world, more recent approaches search for alternatives and develop frameworks which make use of top down connections. In these approaches vision is inherently a constructive process which makes use of a priory information. Following this line of research, a theory of anticipatory vision is outlined and demonstrated by a computational model of primate vision.
