Investigation on hierarchical mechanisms for color processing of the human visual system

本研究探讨了从视网膜到视皮层的分层机制中颜色知觉的色调、饱和度和亮度属性是如何产生的，以及刺激的时空因素如何影响颜色信息的加工。为了建立色视觉信息加工模型，我们主要从以下几个方面进行了研究：1.形状知觉中颜色和亮度信息的相互作用2.颜色信息对视觉搜索的影响3.颜色诱导和颜色模式的可分辨性4.色彩加工中的颜色适应5.表面知觉中的颜色知觉线索，如虚幻轮廓和透明度。

The present study addresses the questions of how the attributes of hue, saturation and brightness in color perception are produced by and how the spatio-temporal factors of stimuli affect the processing of color information in the hierarchical mechanisms from retina to visual cortex. In order to propose the model of the information processes of color vision, we focus on the following aspects of color vision.1.Interaction between color and luminance information in shape perception2.Effect of color information on visual search3.Chromatic induction and discriminability of colored patterns4.Color adaptation in the opponent-color process5.Perceptual cues of color in the surface perception such as illusory contours and transparency.
