Neural Dynamics of Perceptual Grouping: Textures, Boundaries, and Emergent Segmentations

A neural network for enhancing boundaries and surfaces in synthetic aperture radar images

“…How the BCS and FCS fit into a comprehensive theory of biologieal and machine vision called Form-And-Color-And-Depth (FACADE) theory is diseussed in Grossberg (1904). Grossberg and Mingolla (1985a, 1985b, 1987) developed the BCS model to simulate how the visual system detcets, completes, and sharpens boundary segmentations in response to a variety of stimuli. Our present work adapts a recent development of the BCS model which suggests how the laminar, columnar, and map organization of the visual eortex accomplishes boundary segmentation (Grossberg et a.l., 1997).…”

The Structure of Three-Dimensional Object Representations in Human Vision: Evidence From Whole-Part Matching.

“…First, Edelman (1999) has argued that the pattern of results in Biederman and Cooper (1991, Experiment 1) can also be accounted for by edge completion (e.g., Grossberg & Mingolla, 1985). That is, the identical and complementary conditions might have shown equivalent priming effects because of an edge completion mechanism acting on the complementary feature-deleted primes.…”

“…That is, the identical and complementary conditions might have shown equivalent priming effects because of an edge completion mechanism acting on the complementary feature-deleted primes. Edge completion is also likely to be disrupted more by the deletion of specific types of edge features, such as vertices, which provide clues to collinearity and curvilinearity of deleted edge segments (Grossberg & Mingolla, 1985).…”

Probabilistic synaptic weighting in a reconfigurable network of VLSI integrate-and-fire neurons

“…One example of a network architecture that lends itself to ef®cient implementation by our scheme is the boundary contour system (BCS) for image segmentation and boundary completion in the presence of clutter and occlusion (Grossberg & Mingolla, 1985;Grossberg, Mingolla & Williamson, 1995;Mingolla, Ross & Grossberg, 1999).…”

“…In Section 3, we discuss some theoretical issues that arise in networks of integrate-and-®re neurons with probabilistic synapses. In Section 4, we describe how our framework can be applied to implement the early stages of the boundary contour system (Grossberg & Mingolla, 1985), a biological theory of vision processing. In Section 5, we describe a hardware prototype system that demonstrates these ideas.…”
