Illuminant Aware Gamut-Based Color Transfer

This paper proposes a new approach for color transfer between two images. Our method is unique in its consideration of the scene illumination and the constraint that the mapped image must be within the color gamut of the target image. Specifically, our approach first performs a white-balance step on both images to remove color casts caused by different illuminations in the source and target ima...

Chromatic Adaptation and Illuminant Estimation

Chromatic Adaptation is the ability of the human visual system to approximately preserve the appearance of an object color, no matter which light “color” illuminates a particular scene. We perceive a white piece of paper as white, regardless whether viewed under a bluish daylight or yellowish tungsten light source. Similar effects can be observed with other color hues. Figure 1 illustrates this...

Illuminant estimation as cue combination.

This work briefly describes a model for illuminant estimation based on combination of candidate illuminant cues. Many of the research issues concerning cue combination in depth and shape perception translate well to the study of surface color perception. I describe and illustrate a particular experimental approach (perturbation analysis) employed in the study of depth and shape that is useful i...

Illuminant Estimation: Beyond the Bases

We describe spectral estimation principles that are useful for color balancing, color conversion, and sensor design. The principles extend conventional estimation methods, which rely on linear models of the input data, by characterizing the distribution or structure of the linear model coefficients. When the linear model coefficients of the input data are highly structured, it is possible to im...

Consensus-based framework for illuminant chromaticity estimation

bstract. Several algorithms were proposed in the literature to reover the illuminant chromaticity of the original scene. These algoithms work well only when prior assumptions are satisfied, and the est and the worst algorithms may be different for different scenes. e investigate the idea of not relying on a single method but instead onsider a consensus decision that takes into account the repon...
