Gamut Mapping

This image shows the gamuts of a CRT monitor (mesh) and a natural scene (solid) in CIELAB whereby the axes represent the interval of -100 to 100 in a* and b*. Click on the image to see a VRML representation of the gamuts.

Welcome!

This is the home page of CIE Division 8 Technical Committee 8-03 on gamut mapping. If you would like to be involved in this technical committee, or have any questions, comments or suggestions regarding to this page feel free to contact the chairman of this TC. What will be presented next are the terms of reference of this committee, a list of its current members and some of this TC's documents.

Invitation to Participate in CIE Gamut Mapping Study

An essential part of cross-media color image reproduction is to deal with the differences between media in terms of their color gamuts. As a result the CIE has set up a technical committee (TC8-03) on Gamut Mapping and given it the task of recommending a baseline gamut mapping solution. However, as existing published work on gamut mapping is very heterogeneous it was recognized that it is important to collect a substantial set of experimental gamut mapping evaluation results obtained in a coordinated way. Hence TC8-03 has prepared a set of Guidelines for the Evaluation of Gamut Mapping Algorithms and would like to announce their publication as a CIE technical report (CIE 156:2003).

Furthermore we would like to invite you to conduct experimental evaluations of gamut mapping algorithms on the basis of the Guidelines and thereby help us to make a well-founded recommendation for a baseline gamut-mapping algorithm. If you decide to participate in this coordinated research, please inform us of your intent by emailing us and submitting a report on the status of your experimental work to us by September 2004. Also, if you would like others to evaluate some specific gamut mapping algorithms, we would like to encourage you to submit detailed descriptions, pseudo–code or actual code in languages like C or Matlab to this TC so that we can make this available through our website. Finally, please, do not hesitate to contact us if you have any questions about this effort.

Being involved in the definition of a baseline solution for a key part of color reproduction is a great opportunity and we wholeheartedly encourage you to participate in this coordinated research.

UPDATE: All versions of the obligatory ‘Ski’ test image are now available here. Please submit information to the TC if you intend to participate in this study by providing an approximate time-frame for your experiment and the gamut mapping algorithms, test images and media you plan to use.

Terms of Reference

To study, develop and recommend an optimal solution for cross-device and cross-media image reproduction. This solution will provide a standard procedure to calculate the colour gamut of an image, an imaging system, or its components, and either one algorithm, or a set of algorithms and rules for use in specific applications.

Survey of Gamut Mapping Algorithms

Click here to see the TC's Survey of Gamut Mapping Algorithms which gives an algorithm-by-algorithm intruduction to gamut mapping solutions proposed between 1978 and 1999 and also includes a draft of a paper where general gamut mapping concepts are discussed and gamut mappingwork up published by mid-2001 is covered.
