Abstract :
A hybrid vision chip is presented for real-time object-based processing for tasks such as positioning and sizing of enclosed objects. This system presents the first artificial silicon retina capable of position and size determination of multiple objects in true parallel fashion. Based on a novel distributed algorithm, this approach uses the input image to enclose a feedback loop to realise a data-driven pulsating action. The fabricated device is shown to achieve a computation-efficiency of at least 725 million instructions per second per milliwatt and capable of processing up to 2000 frames per second
