A Simple Computational Model of Center-Surround Receptive Fields in the Retina

This report discloses a simple computational model of the outer retinal layers. The algorithm incorporates both rectified on-centeroff-surround and off-centeron-surround bipolar elements, and an increase in the convergence of receptors to output elements that accounts for resolution differences between central and peripheral vision. The phenomenon of even and odd symmetry observed in biological receptive fields can be reproduced by the response of the model system to a moving line....
