Chromatic adaptation transforms are used in imaging system to map image appearance to colorimetry under different illumination sources. In this paper, the performance of different chromatic adaptation transforms (CAT) is compared with the performance of transforms based on RGB primaries that have been investigated in relation to standard color spaces for digital still camera characterization and image interchange. The chromatic adaptation transforms studied are von Kries, Bradford, Sharp, and… 
Content-based computational chromatic adaptation
Based on observations made, new CATs are derived considering the image spatial content, and suitable requirements for CAT are revised and rewritten in a variational formalism.
Chromatic Adaptation Transforms with Tuned Sharpening
This work proposes a new method of calculating chromatic adaptation transforms based on using the extra information available in the illuminants’ spectral power distributions, which gives comparable results to the current tristimulus-based chromatic adaptations in most cases, and better results in some specific situations such as the McCann-McKee-Taylor experiment.

A new chromatic adaptation model is proposed which bases on eye's adaptation of luminance and chromaticity with changes of illumination, which optimizes the visual response to particular view condition of illumination so that color appearance of the color object under different illuminants could be similar or same depending on the degree of adaptation of human view system.
Herding CATs: A Comparison of Linear Chromatic-Adaptation Transforms for CIECAM97s
There are currently five transformation matrices being considered for use in the linear chromatic-adaptation transform in a revision of the CIECAM97s color appearance model, and the HuntPointer-Estevez transform of CIE tristimulus values to normalized cone responsivities is the only one currently under consideration.
Linear Chromatic Adaptation Transform Based on Delaunay Triangulation

Image chromatic adaptation using ANNs for skin color adaptation
An approach to image chromatic adaptation using neural networks (NN) with application for detecting - adapting human skin color with results on detecting skin regions in NN color corrected test images are presented.
Neural Network Approach for Image chromatic Adaptation for Skin Color Detection
The skin regions in the NN stabilized images are successfully detected using a computationally inexpensive thresholding operation and the results are promising and suggest a new approach for adapting human skin color using neural networks.
Modeling a color-rendering operator for high dynamic range images using a cone-response function
In the proposed method, the tone-mapping operator produces visibility and the overall impression of brightness, contrast, and color in HDR images when mapped onto relatively LDR devices and yields an improved color-rendering performance compared to conventional methods.
A Numerical Minimization of Perceptual Error for the Linear Chromatic Adaptation Transform
New sensors for the chromatic adaptation transform (CAT) are found by the independent numerical minimization of 6 perceptual error metrics over 16 corresponding color pair (CCP) data sets, including Lam's set, using as starting point for the minimization 4 known and commonly used sensors.
Dependence of perceived purity of a chromatic stimulus on saturation adaptation.
Investigation of how chromatic adaptation to stimuli with certain saturation influences perceived purity of test stimuli with the same hue but different saturation reveals that saturation adaptation seems to be nonlinear much the same way as the Bezold-Brücke and the Abney effect.


Performance of a Chromatic Adaptation Transform based on Spectral Sharpening
The focus of this paper is comparing the perceptual error between actual appearance and predicted appearance of a color under different illuminants, since it is perceptual error that the Bradford transform minimizes.

The results of these experiments indicated that higher purities are needed in order to produce the same absolute color appearances at low levels of illuminance even when the chromaticities of the adapting lights were equal.
Formulation of a Nonlinear Model of Chromatic Adaptation
A chromatic-adaptation model which consists of a modified von Kries and a succeeding nonlinear transformation is formulated provided that a medium-gray background is always used as an adapting field.
