在人类色彩视觉（色觉）及其工程应用领域内，CIC（Color and Imaging Conference，色彩与成像会议）是每年一届的重要会议。该会议由国际专业协会IS&T（Society for Imaging Science & Technology，成像科学与技术协会）主办。今年是CIC会议的第33届（因此今年的会议代号为CIC33)；此前的CIC会议主要在北美和欧洲举办，今年CIC33将在香港举办，日期为：10/27 ~ 10/31, 2025。这是该会议首次在亚洲举办。

会议网站为：https://www.imaging.org/IST/Conferences/CIC/CIC2025/CIC_Home.aspx 

色觉研究的工程应用包括计算机屏幕和手机上的彩色显示以及彩色相机。今年，华为和小米均是CIC33的赞助商。

CIC33 将提供一些色觉科学和技术的最新进展的短课程（2 小时、4 小时或 8 小时）。其中，我将讲授以下为时 2 小时的在线课程 (10/27/2025 北京时间：10:45 AM - 12:45 PM)：

New Recent Psychological and Physiological Advances in Young-Maxwell-Helmholtz Theory of Color VisionInstructors: Charles Wu, Perception and Cognition Research

Level: IntroductoryDuration: 2 hoursCourse Time: 10:45 - 12:45Prerequisites: A very basic understanding of human color vision (such as gained from a Vision Science or Imaging Science course).

BenefitsThis course enables the attendee to:

• Learn evidence from philosophical, psychological, and physiological perspectives to understand Hering’s Opponent-Colors Theory (OCT) versus the now-widely understood Young-Maxwell-Helmholtz's Trichromatic Theory.

• Relate several visual phenomena with recent findings in visual neuroscience to show evidence that a key mechanism of Young-Maxwell-Helmholtz's Trichromatic Theory relates to the V1-L4 as the neural substrate for color sensations (i.e., color appearance).

Course DescriptionThis course will consist of three parts. First, the theories and models about human color vision at the perceptual/psychophysical level are discussed. For over 140 years, there have been two dominant theories about human color vision: Young-Maxwell-Helmholtz's Trichromatic Theory and Hering's Opponent-Colors Theory (OCT). A recent advance in this domain presents the shortcoming of the OCT—as stated by a review paper in Trends in Cognitive Sciences: “Color appearance and the end of Hering’s OCT” (Conway et al., 2023). This first part reviews prominent arguments and evidence from philosophical, psychological, and physiological perspectives to compare the OCT and the Trichromatic Theory, explaining why the latter is now the currently held theory. Second, the course introduces relevant new advances in visual neuroscience and then correlate some visual phenomena (including the La Hire phenomenon, which is seeing one’s own blind spots) with such advances to show that the V1-L4 (the thalamic recipient layer in the primary visual cortex) is the neural substrate for trichromatic color sensations, thereby establishing this key mechanism of the Trichromatic Theory on a solid neuroscientific basis. Third, the course discusses potential applications of this neuroscientifically based model about human color vision in imaging and display technologies.Charles Q. Wu received his MS in electrical engineering from Nanjing Automation Research Institute (NARI) in China (1988) and his PhD in cognitive psychology from Carnegie Mellon University (1992). From 1992 to 1995, he was a postdoctoral researcher in visual neuroscience at the Institute of Ophthalmology, University College London. He conducts independent research in color vision and binocular vision, primarily from theoretical and computational perspectives. During 2021-2025, he has worked at Meta Reality Labs on eye tracking features in AR/VR device.
