RETINET: a neural network for the psychophysics of color vision

Psychophysics of color perception has demonstrated to be a complex phenomenon, because some illusionary perceptions raised questions about the view that it might be determined by the wavelength composition of the light spectra reflected into the retina. We review the phenomena of color constancy, color induction and colored shadows and develop a neural network with lateral interactions in its input layer, which implements these psychophysical phenomena suggesting a possible explanation for them. The model is based on a simplified neural architecture of the retina
