Six different methods for white-balancing digital images were compared in terms of their ability to produce white-balanced colors close to those viewed under a specific viewing illuminant. [] Key Method 4096 different sets of camera sensitivities were synthesized; 170 objects were evaluated under a canonical viewing illuminant (D65) and six additional taking illuminants (A, D50, D75, F2, F7, and F11). Each white balancing method was exercised in turn, and the mean and 90th percentile ΔE*ab were determined…
Color Balance in LASER Scanner Point Clouds
TLDR
Two approaches for color transfer matching the means and standard deviations is selected because of its superior color balancing and ease of implementation and these two approaches are analyzed and tested in this thesis on images displaying the same scene but with different color casts.
True White Point for Television Screens Across Different Viewing Conditions
TLDR
The results indicated that current white point settings of major television manufacturers are too bluish and neither televisions that meet the current standards nor televisions in the market would appear as true white under the viewing conditions employed in this paper.
Securing Color Fidelity in 3D Architectural Heritage Scenarios
TLDR
An automated solution developed to improve the radiometric quality of an image datasets and the performances of two main steps of the photogrammetric pipeline and the use of a specific weighted polynomial regression is presented.
Increasing camera dynamic range through in-sensor multi-exposure white balancing
TLDR
A new method to adjust the relative sensitivity of color channels based on multi-exposure frame combination is proposed, which offers a digital option for reducing sensitivity for some color channels and aligns the color channels.
Linear Chromatic Adaptation Transform Based on Delaunay Triangulation
TLDR
Objective evaluation showed that the proposed method outperforms existing CAT methods by more than 21%; that is, it performs statistically significantly better than other existing methods.
An efficient spectral-based calibration method for RGB white-balancing gains under various illumination conditions for cell-phone cameras
TLDR
A new technique is proposed which minimizes/simplifies RGB-ratios calibration/estimation process and could be based on either direct image capture or spectral numerical processing--the latter is shown to be more flexible and accurate.
Computational inexpensive two step auto white balance method
TLDR
The proposed method introduces the use of a 2D chromaticity diagram of the image to extract information about the resultant scene reflectance and assumes that the presence of low-saturated colors in the scene will increase the probability of retrieving accurate scene color information.
Two calibration models for compensation of the individual elements properties of self-emitting displays
TLDR
It was found that even for a display with uniform chromatic subpixels characteristics, the linear model with channel mixing is superior in terms of compensation accuracy.
Estimation of Image Sensor Fill Factor Using a Single Arbitrary Image
TLDR
This paper proposes a method to estimate the fill factor of a camera sensor from an arbitrary single image according to the low standard deviation of the estimated fill factors from each of images and for each camera.
Color-difference assessment and enhancement for driving headlight simulation
TLDR
The process of constructing two color acceptability scales that directly reflect the perception of two different populations (experts and “naive”) and the assessment of a method based on the chromatic adaptation transform (CAT) for reducing the color difference between real and virtual environments are conducted.

Color Inconstancy Index: A Proposal and Case Study for Consumer Digital Cameras
TLDR
Adopting the ∆E94* color difference measure, an extended color incon­ stancy index (CII) is used to track the stability of color balancing algorithms across multiple illuminant types by effectively performing a variance analysis with respect to the illuminants variable for multiple color stimuli.
Learning Color Constancy
TLDR
Test the hypothesis that the relationship between an image of a scene and the chromaticity of scene illumination could be learned by a neural network and obtained surprisingly good estimates of the ambient illumination lighting from the network even when applied to scenes in the lab that were completely unrelated to the training data.

This work develops sensor transformations that convert a given set of sensor sensitivity functions into a new set that will improve the performance of any color-constancy algorithm that is based on an independent adjustment of the sensor response channels.
