Abstract
The density and concurrency available in VLSI make it an excellent technology for implementing visual image-processing. By incorporating phototransistors and analog processing elements onto a single die, the large signal bandwidths required for real-time computations can be achieved. This paper describes a VLSI chip that computes the "center of intensity" of a two-dimensional visual field. One application for this network is the localization of a bright spot of light against a dark background. Theoretical and experimental results are presented to describe the operation of the system and its suitability as a input device for tracking servo systems.
