ABSTRACT
In this chapter we consider some of the problems confronting the development of general integrated computer-vision systems and the status of the VISIONS project, which has become an experimental testbed for the construction of knowledge-based image interpretation systems. The goal is the construction of a symbolic representation of the three-dimensional world depicted in a two-dimensional image, including the labeling of objects, the determination of their location in space, and to the degree possible, the construction of a surface representation of the environment.
