Analog MOS circuit systems performing the visual tracking with bio-inspired simple networks

In this paper we propose simple neural networks for the visual-tracking task which are inspired from biological eye-movement systems. Although the proposed system is very simple, the system can pursue the visual objects in the presence of background images. The proposed system consists of velocity sensing circuits, competitive neural circuits and motor control circuits which are contrived to be suitable for a large-scale analog circuit implementation. Results of extensive numerical and SPICE simulations indicate that the proposed circuit can produce the appropriate motor signal for moving visual objects and pursue the object in the presence of background images
