Color constancy is a feature of the human color perception system which ensures that the perceived color of objects remains relatively constant under varying illumination conditions, and therefore closer to the physical reflectance. This perceptual effect, discovered by Helmholtz, was formalized by Land and McCann in 1971, who formulated the Retinex theory. Several theories have ever since been developed, known as Retinex or color constancy algorithms. In particular an important historic… 

Image Enhancement using Thresholding Techniques and Histogram Equalization

Different methods such as least squares and discrete cosine transform are explained as well as how to enhance images using both Land’s idea and histogram equalization are explained.

A Review on Color Constancy Based Image Enhancement

The scope of color constancy is defined in the image enhancement techniques to improve the reliability of applications that depend on consistent color descriptions and also to define the scope of transform domain methods.

Efficient image enhancement using sparse source separation in the Retinex theory

This paper applies the sparse source separation technique to the Retinex theory to present a physics-based algorithm that satisfies the locality characteristic of the original RetineX theory and can very nearly replicate the original image without any special operation.

Eye‐Centered Color Adaptation in Global Illumination

This paper proposes a new color adaptation method well suited to global illumination, which estimates the adaptation color by averaging the irradiance color arriving at the eye by considering the illumination from all the scene.

The Hyper-log-chromaticity space for illuminant invariance

A novel color space inspired by the Log-Chromaticity space is used and modifies the bilateral filter to equalize illumination across objects using a single frame to provide an alternate image with fewer illumination related issues for other algorithms to process.

Scoping review on automatic color equalization algorithm

An overview of the main application domains in which ACE was successfully used and of the different ways in which this algorithm was implemented, modified, used, or compared is provided.

Total generalized variation-based Retinex image decomposition

A reflectance and illumination decomposition model for the Retinex problem via total generalized variation regularization and H 1 decomposition is introduced and is comparable both quantitatively and qualitatively with state-of-the-art methods.

A Total Variation Model for Retinex

A total variation model for Retinex is presented, which assumes spatial smoothness of the illumination and piecewise continuity of the reflection, where the total variation term is employed in the model.

A TV Bregman iterative model of Retinex theory

A feature of the human visual system (HVS) is color constancy, namely, the ability to determine the color under varying illumination conditions. Retinex theory, formulated by Edwin H. Land, aimed

A parallel operator splitting algorithm for solving constrained total-variation retinex

A parallel operator splitting algorithm tailored for the constrained total-variation retinex model, in which all the resulting subproblems admit closed form solutions or can be tractably solved by some subroutines without any internally nested iterations is developed.

A PDE Formalization of Retinex Theory

It is proved that if the paths are assumed to be symmetric random walks, the Retinex solutions satisfy a discrete Poisson equation and this formalization yields an exact and fast implementation using only two FFTs.

The experimental work shows that for good constancy, a color constancy system will need to adjust the gain of the receptors it employs in a fashion analagous to adaptation in humans.

Properties and performance of a center/surround retinex

A practical implementation of the retinex is defined without particular concern for its validity as a model for human lightness and color perception, and the trade-off between rendition and dynamic range compression that is governed by the surround space constant is described.

Improving gamut mapping color constancy

The first result of this paper is to show that only intensity information is lost and it is proved that the feasible set calculated by Forsyth's original algorithm, projected into 2-D, is the same as the feasibleSet calculated by the2-D algorithm.

It is shown that the retinex algorithm is too sensitive to changes in the color of nearby objects to serve as an adequate model of human color constancy.

A multiscale retinex for bridging the gap between color images and the human observation of scenes

This paper extends a previously designed single-scale center/surround retinex to a multiscale version that achieves simultaneous dynamic range compression/color consistency/lightness rendition and defines a method of color restoration that corrects for this deficiency at the cost of a modest dilution in color consistency.

Lightness and retinex theory.

The mathematics of a lightness scheme that generates lightness numbers, the biologic correlate of reflectance, independent of the flux from objects is described.

A series of experiments demonstrated that in images neither the wavelength of the stimulus nor the energy at each wavelength determines the color, and this departure from what the authors expect on the basis of colorimetry is complete.
