Retina model with real time implementation

This paper describes a novel retina model and its implementation. Our modeling approach is neuromorphic. The primary motivation is to deduce an algorithmic skeleton from the measurements and to make possible the on-line parameter changing. The model is tuned for half a dozen different channels with less than half percent spatial-temporal error. An of-the-shelf stand-alone system, the Bi-I, is used to real-time implement this mammalian retina model. The system is capable of computing four retina channels in video real time. The easy on-line control is solved with faders and buttons.
