Abstract

A network for the extraction of salient image structure in dot patterns is proposed which uses a phase diffusion process to label the image into holistic perceptual objects and the background. The image is processed using three successive stages, copying the design of biological visual mechanisms. The population coded direction specific edge representation generated from phase-dependent energy filters is used by a competitive and cooperative phase process to allow boundary completion, grouping of perceptual elements and the suppression of false responses generated by the edge detection stage.
