This book explores a method for symbolically intepreting images based upon a parallel implementation of a network-of-frames suggested, to describe intelligent processing. Traditional methods for image scene interpretation and understanding are based mainly on such single-threaded procedural paradigms as hypothesize-and-test or syntactic parsing. As a result, these systems are unable to carry out tasks that require concurrent hypothesis testing. The system is tested with several scenarios of increasing complexity, culminating with legal interpretation of traffic intersection images.
