The problem of color constancy may be solved if we can recover the physical properties of illuminants and surfaces from photosensor responses. We consider this problem within the framework of Bayesian decision theory. First, we model the relation among illuminants, surfaces, and photosensor responses.

Degree-of-linear-polarization-based Color Constancy
Computer Vision and Pattern Recognition, 2022Color constancy is an essential function in digital photography and a fundamental process for many computer vision applications. Accordingly, many methods have been proposed, and some recent ones have used deep neural networks to handle more complex ...

Journal of the Optical Society of America A, 1986
Observers matched patches (simulated Munsell papers) in two simultaneously presented computer-controlled displays, a standard array presented under 6500-K illumination and a test array under 4000 or 10,000 K. Adaptation to the test illuminants was limited. The adjusted patch was surrounded by a single color (annulus display) or by many colors (Mondrian

Color Constancy Beyond Standard Illuminants
International Conference on Information Photonics, 2022The effects of strong color casts in traditional, learning-based and data-driven color constancy algorithms is analyzed. This is the first study investigating the response of color constancy methods to illuminants on the edges and outside the color ...

Color memory and color constancy
Journal of the Optical Society of America A, 1996Color constancy is the perceived stability of the color of objects despite changes in the light illuminating them. An object's color is considered constant if the current perceived color is judged to be in accord with the remembered one. Thus the accuracy and precision of color memory are fundamental to understanding this classic problem.

Advances in Color Vision, 1992
We have investigated the extent of color constancy in complex (Mondrian) and simple (center-surround) displays. Our critical finding is that the extent of lightness and color constancy in such displays depend heavily on the instructions given to subjects. We also find, not surprisingly, that adaptation has a powerful effect on color constancy. Stimulus

COCOA: Combining Color Constancy Algorithms for Images and Videos
IEEE Transactions on Computational Imaging, 2022We present an efficient combination strategy for color constancy algorithms. We define a compact neural network architecture to process and combine the illuminant estimations of individual algorithms, that may be based on different assumptions over the ...

Truncated Edge-based Color Constancy
2022 IEEE 12th International Conference on Consumer Electronics (ICCE-Berlin), 2022In this paper we propose the truncated edge-based color constancy. It is based on, and extends, the edge-based framework by introducing the use of truncated Gaussian filters.
