| Abstract(in English) | A biological model of vision systems in the lateral eye of limulus was implemented into a simple analog network. The vision system can extract temporal and spatial contrasts from visual scenes. The local signals of temporal and spatial contrasts at each ommatidium, which is a unit element of the lateral eye, are formed by using self-inihibition and lateral inhibition from neighbors, respectively. Simulation results using SPICE showed that the implemented network detected temporal and spatial contrasts expected from the model. The detection of temporal and spatial contrasts is a primitive function in early visual processing. Therefore, the proposed network has the potential to be a basic component of various visual preprocessors. |
