Abstract

Several efforts have been made previously by researchers attempting to mimic biological processing in mammalian retinas to perform such tasks as motion detection/analysis, image requisition, and object position and center of gravity determination. In all these efforts, performance was limited by offsets in the analog circuitry. This paper will discuss a technique referred to as nonnearest neighbour local differencing which improves image feature detection capabilities in low contrast images or noisy environments
