Vis-CRF: A Simplified Filtering Model for Vision

Abstract

Over the last decade, a variety of new neurophysiological experiments have deepened our understanding about retinal cells functionality, leading to new insights as to how, when and where retinal processing takes place, and the nature of the retinal representation and encoding sent to the cortex for further processing. Based on these neurobiological discoveries, we provide computer simulation evidence to suggest that Geometrical illusions are explained in part, by the interaction of multiscale visual processing performed in the retina supporting previous studies [1, 2]. The output of our retinal stage model, named Vis-CRF which is a filtering vision model is presented here for a sample of Café Wall pattern and for an illusory pattern, in which the final percept arises from multiple scale processing of Difference of Gaussians (DoG) and the perceptual interaction of foreground and background elements.
