Two Classes of Color Constancy
Journal of the Illuminating Engineering Institute of Japan, 1997 If a mere apparent color (apparent-color) from an object surface is equal to a color perception as an attribute of the same object surface (surface-color), this condition should be called “perfect color constancy.” If not, the condition should be called “partial color constancy.” We looked into the distinction between these two classes of color ...

Generative Models for Multi-Illumination Color Constancy [PDF]
2021 IEEE/CVF International Conference on Computer Vision Workshops (ICCVW), 2021 In this paper, the aim is multi-illumination color constancy. However, most of the existing color constancy methods are designed for single light sources. Furthermore, datasets for learning multiple illumination color constancy are largely missing.

Relational color constancy in achromatic and isoluminant images [PDF]
, 2000 Relational color constancy, which refers to the constancy of perceived relations between surface colors under changes in illuminant, may be based on the computation of spatial ratios of cone excitations.

Color Constancy for Uniform and Non-Uniform Illuminant Using Image Texture
IEEE Access, 2019 Color constancy is the capability to observe the true color of a scene from its image regardless of the scene’s illuminant. It is a significant part of the digital image processing pipeline and is utilized when the true color of an object is ...

Robust tracking for augmented reality [PDF]
, 2015 In this paper a method for improving a tracking algorithm in an augmented reality application is presented. This method addresses several issues to this particular application, like marker-less tracking and color constancy with low quality cameras, or

Domain Adversarial Learning for Color Constancy
International Joint Conference on Artificial Intelligence, 2022 Color Constancy aims to eliminate the color cast of RAW images caused by non-neutral illuminants. Though contemporary approaches based on convolutional neural networks significantly improve illuminant estimation, they suffer from the seriously ...

Photometric, geometric and perceptual factors in illumination-independent lightness constancy [PDF]
, 2006 It has been shown that lightness constancy depends on the articulation of the visual field (Agostini & Galmonte, 1999). However, among researchers there is little agreement about the meaning of “articulation.” Beyond the terminological heterogeneity ...
