Unique hue settings of 185 observers under two room lighting conditions were used to evaluate the accuracy of mixed chromatic adaptation transform models of CIECAM02 in terms of unique hue reproduction. The current CIE recommendation for mixed chromatic adaptation ratio produced unsatisfying performance in terms of perceptual hue shifts in CIECAM02. Using our large data set of unique hue data as a benchmark, an optimised parameter is suggested for chromatic adaptation under mixed illumination conditions that produces more accurate results in unique hue reproduction.

  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, and a vibrant interactive papers session. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper presentation.
