Region Adaptive Color Demosaicing Algorithm Using Color Constancy
EURASIP Journal on Advances in Signal Processing, 2010 This paper proposes a novel way of combining color demosaicing and the auto white balance (AWB) method, which are important parts of image processing.

REMOVING SHADOWS FROM HIGH-RESOLUTION URBAN AERIAL IMAGES BASED ON COLOR CONSTANCY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 A method is explored to remove tall building shadows in true color and color infrared urban aerial images based on the theory of color constancy. This paper first uses the specthem ratio and Otsu threshold segmentation methods to detect building shadows ...

Generative Models for Multi-Illumination Color Constancy [PDF]
, 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.

IEEE Access, 2020 In the human and computer vision, color constancy is the ability to perceive the true color of objects in spite of changing illumination conditions. Color constancy is remarkably benefitting human and computer vision issues such as human tracking, object

Adaptive colour constancy algorithm using discrete wavelet transform [PDF]
, 2012 The colours of chromatically homogeneous object surfaces measured by a sensor vary with the illuminant colour used to illuminate the objects. In contrast, colour constancy enables humans to identify the true colours of the surfaces under varying ...

Mechanisms of color constancy [PDF]
Journal of the Optical Society of America A, 1986 We develop a model of how the visual system finds the colors of objects that have unknown shapes and positions. The model relies on mechanisms of light adaptation, coupled with eye movements, to recover three descriptors of surface reflectance that are represented in the signals of an achromatic mechanism and two color-opponent mechanisms.

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 ...

A Benchmark for Burst Color Constancy
, 2021 <p>Burst Color Constancy (CC) is a recently proposed approach that challenges the conventional single-frame color constancy. The conventional approach is to use a single frame - shot frame - to estimate the scene illumination color.

Color Constancy with Derivative Colors
CoRR, 2016 Information about the illuminant color is well contained in both achromatic regions and the specular components of highlight regions. In this paper, we propose a novel way to achieve color constancy by exploiting such clues. The key to our approach lies in the use of suitably extracted derivative colors, which are able to compute the illuminant color ...

Color constancy in philosophy and science [PDF]
, 2019 Color constancy is the phenomenon in which the visual system reliably ensures that objects that are the same color continue to look the same color despite, what one might call, interference. It is frequently appealed to in philosophy to support a myriad
