[PDF][PDF] A curious problem with using the colour checker dataset for illuminant estimation

GD Finlayson, G Hemrit, A Gijsenij… - Color and Imaging …, 2017 - library.imaging.org
In illuminant estimation, we attempt to estimate the RGB of the light. We then use this
estimate on an image to correct for the light's colour bias. Illuminant estimation is an …

Adaptive color constancy using faces

S Bianco, R Schettini - IEEE transactions on pattern analysis …, 2014 - ieeexplore.ieee.org
In this work we design an adaptive color constancy algorithm that, exploiting the skin regions
found in faces, is able to estimate and correct the scene illumination. The algorithm …

A fast white balance algorithm based on pixel greyness

B Thai, G Deng, R Ross - Signal, Image and Video Processing, 2017 - Springer
The goal of automatic white balance (AWB) is to maintain colour constancy of an image by
removing colour cast caused by un-canonical illuminant. In this paper, we address two …

[PDF][PDF] White point estimation for uncalibrated images

VC Cardei, B Funt, K Barnard - Color and Imaging Conference, 1999 - library.imaging.org
Color images often must be color balanced to remove unwanted color casts. We extend
previous work on using a neural network for illumination, or white-point, estimation from the …

Computational color constancy

S Bianco, R Schettini - 3rd European Workshop on Visual …, 2011 - ieeexplore.ieee.org
Computational color constancy aims to estimate the actual color in an acquired scene
disregarding its illuminant. Many illuminant estimation solutions have been proposed in the …

Auto white-balance correction for mixed-illuminant scenes

M Afifi, MA Brubaker, MS Brown - Proceedings of the IEEE …, 2022 - openaccess.thecvf.com
Auto white balance (AWB) is applied by camera hardware at capture time to remove the
