Physiologically-motivated vision system for pursuing a moving target

We present a physiologically-motivated vision system for pursuing a moving target. First, the relevancy to other biologically-oriented vision systems are summarized and prominent features of our model are described. Especially, we show how to compute the velocity of a target. Secondly, we introduce a system configuration of the present model and explain some characteristics on its visual processing. We regard our model as a negative-feedback system controlled by velocity estimated from retinal images and put emphasis on the time-delay element of the system. In an attempt to clarify its importance, we conducted some simulations with respect to the time-delay element. Finally, we propose a putative mechanism of adjusting the position of a target on the retina toward its center.
