Neural Dynamics for the Perception of Illusory Contours
The unrevealing of neuronal mechanisms responsible for the generation of illusory contours is important both for a better understanding of the human visual system and the improvement of an image segmentation method trying to imitate human performance. Studies of the human visual system support the conjecture that this segmentation process is purely preattentive [2,23,14] occurring at early visual stages [26,5,12,27]. We have extended existing schemes for boundary perception and completion [24,6,7,22,15,8,17,21,28] by a relaxation labeling mechanism  which groups the phases of parametric neural oscillators into perceptual objects exploiting simple geometric constraints between the basic features. The proposed model consists of three successive processing stages which model some of the mechanisms found in visual cortex.
