A Neural Model of Illusory Contour Perception
Illusory contours result from occlusion by a surface whose border is not defined by a continuous discontinuity in any image attribute. Available explanations assume that contrast information on both sides of a gap is sufficient to complete an illusory contour. Using a computer simulation we evaluated this hypothesis by making explicit physiological and psychophysical constraints. Our results indicate that a solution to illusory contour perception may lie with a recurrent network which integrates information about visual surfaces with available contour information.
