Abstract :
This tutorial paper presents a marriage between analog computation paradigm and modem VLSI integration technology in artificial vision machine design. Some typical analog computation circuits for vision applications are presented in order to give a comprehensive view of the possibility of cellular analog computation. A retina is only a knowledge based smart image sensor, except some very specific applications, it should be interfaced with digital processor for higher level processing and interpretation. A good partition between these two parts can conduct to very efficient image processing architecture. This has been demonstrated by an analog retina based stereovision system
