Texture segregation by visual cortex: Perceptual grouping, attention, and learning
A neural model called dARTEX is proposed of how laminar interactions in the visual cortex may learn and recognize object texture and form boundaries. The model unifies five interacting processes: region-based texture classification, contour-based boundary grouping, surface filling-in, spatial attention, and object attention. The model shows how form boundaries can determine regions in which sur...

متن کاملComputational Modeling of Visual Texture Segregation
Visual texture segregation is the perceptual phenomenon illustrated in figure 17.1. In this image a rectangular area composed of small X-shaped patterns appears as a distinct region against a background of L-shaped patterns. This segregation occurs rapidly and unconsciously, without effort or search. The rectangular area composed of Tshaped patterns, however, does not appear as a distinct regio...
متن کاملTexture Segregation and Texture Transparency
This paper reviews the literature on texture segregation and texture transparency, and proposes a new account of texture transparency based on the theory of texture segregation. To date, it has been suggested that the perception of transparency might stem from perceptual grouping or spacing effects between texture elements. Based on recent data, this paper argues that texture transparency shoul...
متن کاملVisual saliency and texture segregation without feature gradient.
A central notion in the study of texture segregation is that of feature gradient (or feature contrast). In orientation-based texture segregation, orientation gradients have indeed played a fundamental role in explaining behavioral results. Here, however, we show that general, smoothly varying, orientation-defined textures (ODTs) exhibit striking perceptual singularities that are completely unpr...
