We introduce a context for testing computational color constancy, specify our approach to the implementation of a number of the leading algorithms, and report the results of three experiments using synthesized data. Experiments using synthesized data are important because the ground truth is known, possible confounds due to camera characterization and pre-processing are absent, and various fact...

As new displays and cameras offer enhanced color capabilities, there is a need to extend the precision of digital content. High Dynamic Range (HDR) imaging encodes images and video with higher than normal bit-depth precision, enabling representation of the complete color gamut and the full visible range of luminance. This thesis addresses three problems of HDR imaging: the measurement of visibl...

A new color encoding specification known as Reference Output Medium Metric RGB (ROMM RGB) is defined. This color encoding is intended to be used for storing, interchanging and manipulating images that exist in a rendered image state without imposing the gamut limitations normally associated with device-specific color spaces. ROMM RGB was designed to provide a large enough color gamut to encompa...

p d i bstract. Several techniques for the computation of gamut boundries have been presented in the past. In this article we take an n-depth look at some of the gamut boundary descriptors used when erforming today’s gamut mapping algorithms. We present a ethod for evaluating the mismatch introduced when using a decriptor to approximate the boundary of a device gamut. First, a isually verified r...

Compared with the planar color gamut, stereoscopic gamut is more uniform, it can reflect actual situation of display system by considering changes in brightness. In this article we introduce another advantage using external factors system, such as influence spectral reflectivity screen. When space converted from CIEXYZ to CIELAB, use a fixed white point, these results are intuitive and reasonab...

KAKODKAR, ATISH PANDURANG. Interpolation and Extrapolation in Color Systems. (Under the direction of Prof. Sarah A. Rajala and Prof. H. Joel Trussell.) With the increased use of color in desktop publishing applications has come a desire for greater control of the color quality. Colorimetric reproduction requires calibrated color output devices. One approach to color calibration is to characteri...
