Construction of Illusory Surfaces by Intermediate-Level Visual Cortical Networks
A model is proposed which directly links the perception of illusory contours to intermediate-level cortical processes for visual surface discrimination. An important assertion of the model is that illusory contours are reentered, via feedback, into surface discrimination processes with the result being the construction of illusory surfaces. The model is tested in a number of simulations which demonstrate surface completion, generation of illusory contours, and interactions with depth cues from stereopsis.
