Enhancing the SGCK Colour Gamut Mapping Algorithm
نویسندگان
چکیده
The SGCK gamut mapping algorithm suggested by CIE TC8-03 has been enhanced by introducing a two-step procedure. Firstly, SGCK is used for gamut mapping the image onto a convex hull representation of the reproduction gamut. The resulting image is then further mapped onto a more realistic representation of the reproduction gamut using hue-angle preserving minimum ∆E∗ ab clipping. Panel testing with fifteen test persons, six different test images, and two different printers shows that this technique gives significantly better results than SGCK.

A New Method for Color Gamut Mapping by Genetic Algorithm
To reproduce an image, it is necessary to map out of gamut colors of the image to destination gamut. It is clear that the best color gamut mapping introduces the perceptually closest image to the original one. In this study, a new color gamut mapping is purposed by the aid of Genetic Algorithm (GA). The color difference between the original and mapped images based on S-LAB formula was chosen as...
متن کاملCalculating Medium and Image Gamut Boundaries for Gamut Mapping
The Segment Maxima Method for calculating gamut boundary descriptors of both colour reproduction media and colour images is introduced. Methods for determining the gamut boundary along a given line of mapping used by gamut mapping algorithms are then described, whereby these methods use the Gamut Boundary Descriptor obtained using the Segment Maxima Method. Throughout the article, the focus is ...
متن کاملA Multi-Resolution, Full-Colour Spatial Gamut Mapping Algorithm
A multi–resolution, full–colour spatial gamut mapping algorithm (GMA) is proposed in this paper. Its aim is to maintain as much of an original image’s overall, and in particular spatial, information as possible within the limits of a reproduction medium’s gamut. First, the original image is decomposed into different spatial frequency bands. Second, lightness compression and initial gamut mappin...
متن کاملSkin chromaticity gamuts for illumination recovery
Colour constancy algorithms range from image statisticsbased pixel intensity manipulation to gamut-mapping methods, and are generally independent of specific image contents. In previous work, we have demonstrated that natural polychromatic surfaces possess distinct chromatic signatures in conecontrast space that may be exploited for colour constancy, and that in human vision, colour constancy i...
متن کاملColour Gamut Mapping as a Constrained Variational Problem
We present a novel, computationally efficient, iterative, spatial gamut mapping algorithm. The proposed algorithm offers a compromise between the colorimetrically optimal gamut clipping and the most successful spatial methods. This is achieved by the iterative nature of the method. At iteration level zero, the result is identical to gamut clipping. The more we iterate the more we approach an op...
