Multi-dimensional property of visual perception has been analyzed in terms of the concept of parallel processing of visual system. The problems addressed are how various perceptual attributes such as color, depth and form are extracted by separate channels in the visual system and how these different attributes are synthesized to create a unified picture of the object. In this study, we have focused on the operation of the parallel systems of luminance and color channels for the perceptual processing of static visual iorms. Psychophysical measurements have been carried out to clarify the mechanisms responsible for the formation of illusory phenomena observed in contour perception. We have found that the form perception involves concurrent processing of different cues of luminance and color in a complex manner.

从视觉系统并行处理的概念出发，分析了视觉感知的多维性。解决的问题是如何通过视觉系统中的不同通道提取各种感知属性，如颜色，深度和形式，以及如何将这些不同的属性合成以创建物体的统一图像。在本研究中，我们重点研究了亮度和颜色通道并行系统在静态视觉图像感知处理中的作用。心理物理测量已经进行，以澄清负责在轮廓感知观察到的错觉现象的形成机制。我们发现，形式感知涉及以复杂的方式并发处理不同的亮度和颜色线索。
