Cie Colour Appearance Models and Associated Colour Spaces

In 1931, the Commission Internationale de l’Eclairage (CIE) recommended a colour specification system. After various additions over the years it now includes a series of colorimetric measures such as the tristimulus values ( XYZ ), chromaticity coordinates, dominant wavelength, and excitation purity for colour specification and colour matching, CIELAB and CIELUV colour spaces for presenting col...

A Comparison between CIECAM97s and its Revised Colour Appearance Models for Apearance Attributes of Fabrics

: The CIECAM97s and its revision, as a colour appearance model, were applied for a series of fabrics with different colours and depths to explain their colour appearance coordinates in similar viewing conditions. The results show that due to some modifications which expand the scale, the modified model has improved capadilities in calculating chroma. Besides, the calculations were simpler for t...

Object knowledge modulates colour appearance

We investigated the memory colour effect for colour diagnostic artificial objects. Since knowledge about these objects and their colours has been learned in everyday life, these stimuli allow the investigation of the influence of acquired object knowledge on colour appearance. These investigations are relevant for questions about how object and colour information in high-level vision interact a...
