The LogLuv Encoding for Full Gamut, High Dynamic Range Images

by Gregory Ward Larson , 1998
"... The human eye can accommodate luminance in a single view over a range of about 10,000:1 and is capable of distinguishing about 10,000 colors at a given brightness. By comparison, typical computer monitors have a luminance range less than 100:1 and cover about half of the visible color gamut. Despite ..."

A survey of outlier detection methodologies

by Victoria J. Hodge, Jim Austin - Artificial Intelligence Review , 2004
"... Abstract. Outlier detection has been used for centuries to detect and, where appropriate, remove anomalous observations from data. Outliers arise due to mechanical faults, changes in system behaviour, fraudulent behaviour, human error, instrument error or simply through natural deviations in populat ..."

but now, principled and systematic techniques are used, drawn from the full gamut of Computer Science and Statistics. In this paper, we introduce a survey of contemporary techniques for outlier detection. We identify their respective motivations and distinguish their advantages and disadvantages in a

Overcoming Gamut and Dynamic Range Limitations in Digital Images

by Gregory Ward Larson , 2001
"... The human eye can accommodate luminance in a single view over a range of about 10,000:1 and is capable of distinguishing about 10,000 colors at a given brightness. By comparison, typical CRT displays have a luminance range less than 100:1 and cover about half of the visible color gamut. Despite this ..."

out-of-gamut (and out-of-range) pixels in a supplemental image, suitable as a layer extension to the Flashpix standard. This data can then be recombined with the original RGB layer to obtain a high dynamic range image covering the full gamut of perceivable colors. Finally, we demonstrate the power

Color gamut of halftone reproduction

by Stefan Gustavson - J. Imaging Sci. Technol , 1997
"... Colour mixing by a halftoning process, as used for colour reproduction in graphic arts and many forms of digital hardcopy, is neither additive nor subtractive. Halftone colour reproduction with a given set of primary colours is heavily influenced not only by the colourimetric properties of the full- ..."

Color Gamut Matching for Tiled Display Walls

by J. Deisinger, A. Kunz (editors, Grant Wallace, Han Chen, Kai Li
"... This paper presents a non-parametric full-gamut color matching algorithm. Color matching is important for the seamless appearance of tiled displays. In particular we address the case where the tiled display is composed of different types of projectors or DLP projectors with white enhancement. White ..."

Visualization of Expanded Printing Gamuts Using 3-Dimensional Convex Hulls

by Karl Guyler - American Ink Maker , 2000
"... Abstract: A 3-D convex hull program, Qhull, was applied to data sets consisting of the Neugebauer primaries and selected multicolor traps of 4-, 5- and 6-color printing systems. Program output was plotted as polytopes, curved surface solids or wireframes in CIE Lab space in full color. These produce ..."

. These produced a 3-D representation of a lithographic printing gamut. Superposition of two or more gamuts affords users full color visual feedback of where, what color and how much color enhancement was brought about by changes of inks or stocks. These techniques provide far more detail than traditional 2-D

Expanding display color gamut beyond the spectrum locus,” Color Res

by Rodney L. Heckaman, Mark D. Fairchild - Appl , 2006
"... Abstract: Digital video and display media are at a “sweet spot ” of growth with brighter and more colorful digital projectors and displays available seemingly every day. Much more is possible in achieving brighter and more vibrant colors, colors that may even transcend our typical experience in term ..."

Gamut Extension for Cinema: Psychophysical Evaluation of the State of the Art, and a New Algorithm

by Syed Waqas Zamir, Javier Vazquez-corral
"... Wide gamut digital display technology, in order to show its full potential in terms of colors, is creating an opportunity to develop gamut extension algorithms (GEAs). To this end, in this work we present two contributions. First we report a psychophysical evaluation of GEAs specifically for cinema ..."

IEEE JOURNAL OF SELECTED TOPICS IN SIGNAL PROCESSING 1 Gamut Mapping in Cinematography through Perceptually-based Contrast Modification

by Syed Waqas Zamir, Javier Vazquez-corral
"... Abstract—Gamut mapping transforms the colors of an input image to the colors of a target device so as to exploit the full potential of the rendering device in terms of color rendition. In this paper we present spatial gamut mapping algorithms that rely on a perceptually-based variational framework. ..."

Full Color Reflective Electronic Media

by Qin Liu, Zhang-lin Zhou, Brad Benson, Gregg Combs, Jong-souk Yeo, Jeff Mabeck, Tim Koch, Dick Henze

A great challenge in realizing the potential of reflective electronic media is achieving vivid full colors that match or exceed the color gamut described by printing standards such as the Specifications for Newsprint Advertising Production (SNAP).
