Analysis of multi-dimensional properties of form perception.

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诸如颜色、深度和形状的各种感知属性，以及如何合成这些不同的属性以创建对象的统一画面。在这项研究中，我们重点研究了亮度和颜色通道的并行系统在静态视觉信息知觉加工中的运作。已经进行了心理物理测量，以澄清在轮廓感知中观察到的幻觉现象的形成机制。我们发现，形状知觉涉及以一种复杂的方式同时加工不同的亮度和颜色线索。

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.
