The essential resource for readers needing to understand visual perception and for those trying to produce, reproduce and measure color appearance in various applications such as imaging, entertainment, materials, design, architecture and lighting. This book builds upon the success of previous editions, and will continue to serve the needs of those professionals working in the field to solve practical problems or looking for background for on-going research projects. It would also act as a good course text for senior undergraduates and postgraduates studying color science. The 3rd Edition of Color Appearance Models contains numerous new and expanded sections providing an updated review of color appearance and includes many of the most widely used models to date, ensuring its continued success as the comprehensive resource on color appearance models. Key features: Presents the fundamental concepts and phenomena of color appearance (what objects look like in typical viewing situations) and practical techniques to measure, model and predict those appearances. Includes the clear explanation of fundamental concepts that makes the implementation of mathematical models very easy to understand. Explains many different types of models, and offers a clear context for the models, their use, and future directions in the field.

There is an ever-increasing demand for a standard way to transport colours among devices on the Internet, and for achieving colour fidelity across digital media. The rapid growth in colour imaging technology has led to the emergence of colour management systems. These systems require colour appearance models so that images produced in one medium and viewed in a particular environment, may be reproduced in a second medium and viewed under different conditions. The eagerly anticipated second edition of Colour Appearance Models brings the fundamental issues and current solutions in the area of colour appearance modelling together in a single place for those needing to solve practical problems or looking for background for ongoing research projects. This book provides the relevant information for an updated review of colour appearance and provide details of many of the most widely used models to date, for example, Nayatani et al., Hunt, and RLAB and the ATD and LLAB appearance models that are of increasing interest for some applications. It also includes the recently formulated CIECAM02 model that represents a significant improvement of CIECAM97S and is the best possible model based on current knowledge. Fairchild presents an updated overview of device-independent colour imaging and finally introduces the concept of image appearance modelling as a potential future direction for colour appearance modelling research. A website accompanies this text that lists developments, publications and calculations related to the material in this book.
Color-appearance Modeling for Cross-media Image Reproduction
"Five color-appearance transforms were tested under a variety of conditions to determine which is best for producing CRT reproductions of original printed images. The transforms included: von Kries chromatic adaptation, CIELAB color space, RLAB color appearance model, Hunt's color appearance model, and Nayatani's color appearance model. It was found that RLAB produced the best matches for changes in white point, luminance level, and background changes, but did not accurately predict the effect of surround. The ability of CIELAB color space was equal to that of RLAB in many cases, and performed better for changes in surround. Expert observers generated CRT images in one viewing condition that they perceived to match an original image viewed in another condition. This technique produced images that were equal to or better than the best color appearance model tested and is a useful technique to generate color appearance data for developing new models and testing existing models."--Abstract.
