Abstract
A simple two-stage lateral-inhibition mechanism is described that permits edges due to changes in surface illumination and orientation to be distinguished directly in the retina from those due to changes in spectral reflectivity. It is based on the assumption that the spectral content of the reflected light changes across a reflectivity edge, whereas it remains relatively constant across an illumination edge.
