CVPR 2001 Short Course

Color Appearance Models

Instructor: Mark Fairchild (Rochester Institute of Technology)

Duration: 4 hours

DESCRIPTION:

This short course provides a detailed review of the international-standard CIECAM97s color appearance model as well as covering the fundamental phenomena and techniques of color appearance modeling. Color-appearance models extend basic colorimetry, as typified by CIE tristimulus values, to the prediction of color matches and color appearance across widely varying viewing conditions. Advances in open systems for digital imaging have accented the need for accurate and efficient color-appearance models to allow transformation of image data across media and viewing conditions.

Tutorial participants will be able to:

· Understand the relationship of color appearance with basic colorimetry,

· Define important color appearance phenomena and terminology,

· Summarize the formulation of color appearance models,

· Compare the formulation of various appearance models and color spaces,

· Implement and use the CIECAM97s model,

· Judge the utility of color appearance models in their application.

This tutorial is intended for scientists and engineers who are involved in either designing or working with systems that produce or reproduce colored objects or images in various media and/or to be observed under varying viewing conditions.

BIOGRAPHY:

Mark D. Fairchild is Director of the Munsell Color Science Laboratory and Professor of Color Science and Imaging Science at Rochester Institute of Technology. He received his B.S. and M.S. degrees in Imaging Science from RIT and his Ph.D. in Vision Science from the University of Rochester. Dr. Fairchild is active in ISCC, IS&T, CIE, SID, OSA, and ACM-SIGGRAPH. He served as chair of CIE TC1-34, which formulated the CIECAM97s color appearance model, and is currently a member of several other CIE committees and the CIE reporter on color appearance models. He received the 1995 Bartleson Award from the Color Group (Great Britain) for his research in color appearance and other aspects of color science. Dr. Fairchild serves as the Color Imaging Editor for the Journal of Imaging Science and Technology and on the technical committees for the Color Imaging Conference, the European Conference on Color in Graphics, Imaging, and Vision, the AIC Color 01 Congress, and the International Conference on Multispectral Color Science.
