Perceptual Organization Based on Temporal Dynamics

A figure-ground segregation network is proposed based on a novel boundary pair representation. Nodes in the network are boundary segmentsobtained through local grouping. Each node is excitatorily coupledwith the neighboring nodes that belong to the same region, and inhibitorily coupled with the corresponding paired node. Gestalt grouping rules are incorporated by modulating connections. Thestatus of a node represents its probability being figural and is updated according to a differential equation.
