描述了使用实时视觉处理理论来分析真实的和虚幻的轮廓形成，轮廓和亮度的相互作用，氖色传播，互补色诱导，和填充的折扣光源和暗点。该理论也物理解释和推广EH土地（见记录1979-05257-001）retinex理论。这些现象可以追溯到适应过程，克服视觉摄取的限制，以合成外部世界的信息视觉表示。两个平行的轮廓敏感过程相互作用，产生理论的亮度，颜色和形式估计。边界轮廓处理对场景边缘中的方向和对比度的量敏感，但对对比度的方向不敏感。它综合了对风景元素的全球配置敏感的边界。特征轮廓处理对方向不敏感，但对场景边缘的对比度和对比度方向都敏感。它触发了一个扩散填充的特征质量内的感知域，其边界是由完成的边界轮廓。边界轮廓过程被假设为包括由视觉皮层17区中的超柱发起的皮层相互作用。特征轮廓过程被假设为包括由17区细胞色素氧化酶染色斑点发起的皮质相互作用。从纹状体和前纹状体视觉皮层的实验数据进行审查，并根据这些数据进行测试的预测。(92参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Describes the use of a real-time visual processing theory to analyze real and illusory contour formation, contour and brightness interactions, neon color spreading, complementary color induction, and filling-in of discounted illuminants and scotomas. The theory also physically interprets and generalizes EH Land's (see record 1979-05257-001) retinex theory. These phenomena are traced to adaptive processes that overcome limitations of visual uptake to synthesize informative visual representations of the external world. Two parallel contour-sensitive processes interact to generate the theory's brightness, color, and form estimates. A boundary contour process is sensitive to orientation and amount of contrast but not to direction of contrast in scenic edges. It synthesizes boundaries sensitive to the global configuration of scenic elements. A feature contour process is insensitive to orientation but sensitive to both amount of contrast and to direction of contrast in scenic edges. It triggers a diffusive filling-in of featural quality within perceptual domains whose boundaries are determined by completed boundary contours. The boundary contour process is hypothesized to include cortical interactions initiated by hypercolumns in Area 17 of the visual cortex. The feature contour process is hypothesized to include cortical interactions initiated by the cytochrome oxydase staining blobs in Area 17. Data from striate and prestriate visual cortex experiments are reviewed, and predictions based on these data are tested.(92 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
