Role of Retinocortical Processing in Spatial Vision
Abstract
This project was an attempt to understand the major functions of early vision by considering how various components cooperate in preparing visual information to organize our perceptions of the world around us. To this end, and with the cooperation of SRI's Machine Vision Group, we assembled some of these functions in a computational working model, which can graphically display the spatial structure of the formation at a given stage of the visual process, in the form of a two-dimensional intensity array (or 'image'). This capability was developed to facilitate the study and comparison of retinal and cortical inputs and outputs of spatial information. The individual components of the model are well known, and the relations among them are based on available data from the literature. However, two aspects of this project seem novel. One is the exploitation of powerful, state-of-the-art tools of computational vision, such as Symbolics 3600-series LISP machines, to create and display our results. These tools were developed primarily for artificial intelligence purposes; they have rarely been used for basic studies in human vision. (JES)
