(p.8) Chapter 1 The Philosophy and the Approach

David Marr

The MIT Press

This chapter discusses the philosophy of visual perception. The systems for solving an information-processing problem are explained. The twin strands of process and representation are specifically addressed. The chapter suggests that there is no ground for arguing that the brain operates so differently from a computer that a computer could not be programmed to perform the same tasks. It also shows that the overall framework divides the derivation of shape information from images into three representational stages: (1) the representation of properties of the two-dimensional image; (2) the representation of properties of the visible surfaces in a viewer-centered coordinate system; and (3) an object-centered representation of the three-dimensional structure and of the organization of the viewed shape, together with some description of its surface properties.

Keywords:   visual perception, philosophy, information-processing problem, brain, computer, shape information, representational stages
