The sharing and exchange of color images over the Internet pose very challenging problems to color science and technology. Emerging color standards will solve many of the problems we face today, but existing images of unknown origin and output devices of unknown calibration will continue to cause problems for many users. This paper presents a brief overview of available solutions to some of the problems and suggests some directions for future research. Although most existing solutions are quite [primitive and fragile, the rapid advance of computing technology promises to bring more sophisticated and intelligent image processing algorithms to common practical use. Image understanding, scene physics, visual calibration, and image perception are four areas of research that are beginning to make good progress toward a fully automatic quality optimization system for color imaging applications.
