Abstract : An electronic computer which operates on two-dimensional visual images is described. The Visual Image Processor (V.I.P.) is designed to compute on data obtained from image points and their near neighbors. The number of types of computations which can be performed is very large: computation with both digital (quantized) and analog (continuous) signals is possible. The heart of the computer is three cathode-ray electrostatic storage tubes, used as the data storage system. Computation is performed by combining video signals obtained by simultaneously offset-scanning the images recorded in two tubes and writing the outcome of operations performed on the two signals as the newly created image in a third tube. This computing process can be repeated indefinitely if noise considerations are minimized. An algorithm for a possible corner detection scheme is developed to study the variety and kind of operations that arise in parallel computation and which suggests specifications for the V.I.P. Decisions are made in the systems planning and all electronic circuitry used in the V.I.P. are described in detail, as are the tests used to measure its performance. Recommendations are made for further improvement in the performance of the machine. (Author)
