Abstract

A neural network architecture for the segmentation and recognition ofcolored and textured visual stimuli is presented. The architecture is basedon the Boundary Contour System and Feature Contour System (BCS/FCS) of S.Grossberg and E. Mingolla. The architecture proposes abiologically-inspired mechanism for color processing based on antagonistinteractions. It suggests how information from different modalities (i.e.color or texture) can be fused together to form a coherent segmentation ofthe visual scene. It identifies two stages of visual pattern recognition,namely, a global preattentive recognition of the visual scene followed by alocal attentive recognition within a particular visual context. The globaland local classification and recognition of visual stimuli use ART-typemodels of G. Carpenter and S. Grossberg for pattern learning andrecognition based on color and texture. One example is presentedcorresponding to an figure-figure separation task. The architectureprovides a mechanism for segmentation, categorization and recognition ofimages from different classes based on self-organizing principles ofperception and pattern recognition.
