Modeling pigmented materials for realistic image synthesis
Chet S. Haase, Gary W. Meyer
Pages: 305-335
DOI: 10.1145/146443.146452
This article discusses and applies the Kubelka-Munk theory of pigment mixing to computer graphics in order to facilitate improved image synthesis. The theories of additive and subtractive color mixing are discussed and are shown to be...

A practical approach to calculating luminance contrast on a CRT
William B. Cowan, Blair MacIntyre
Pages: 336-347
DOI: 10.1145/146443.146467
Luminance contrast is the basis of text legibility, and maintaining luminance contrast is essential for any color selection algorithm. In principle, it can be calculated precisely on a sufficiently well-calibrated display surface, but...

Color quantization by dynamic programming and principal analysis
Xiaolin Wu
Pages: 348-372
DOI: 10.1145/146443.146475
Color quantization is a process of choosing a set of K representative colors to approximate the N colors of an image, K < N, such that the resulting K-color image looks as...

An analysis of selected computer interchange color spaces
James M. Kasson, Wil Plouffe
Pages: 373-405
DOI: 10.1145/146443.146479
Important standards for device-independent color allow many different color encodings. This freedom obliges users of these standards to choose the color space in which to represent their data. A device-independent interchange color space must...

Precision requirements for digital color reproduction
Mark D. Fairchild, Roy S. Berns, Mike Stokes
Pages: 406-422
DOI: 10.1145/146443.146482
An environment was established to perform device-independent color reproduction of full-color pictorial images. In order to determine the required precision for this environment, an experiment was performed to psychophysically measure...
