Classification-Based Color Constancy
2008In this work, we investigate how illuminant estimation techniques can be improved using indoor/outdoor classification. The illuminant estimation algorithms considered are derived from the framework recently proposed by Van de Weijer and Gevers.

Estimating the color of the illuminant under which an image of a scene was captured is a central part of solving the color constancy problem: that is, of deriving an illuminant independent representation of the reflectance's in a scene. In this article we develop a general correlation framework for solving the illuminant estimation problem. Within this

When Color Constancy Goes Wrong: Correcting Improperly White-Balanced Images
Computer Vision and Pattern Recognition, 2019This paper focuses on correcting a camera image that has been improperly white-balanced. This situation occurs when a camera's auto white balance fails or when the wrong manual white-balance setting is used.

This chapter presents an account of color constancy that explains a well-known division in the data from color-constancy experiments: So-called “paper matches” exhibit a much higher level of constancy than so-called “hue-saturation matches.” It argues that the visual representation of objective color is the representation of something associated with a

We introduce a novel formulation of temporal color constancy which considers multiple frames preceding the frame for which illumination is estimated. We propose an end-to-end trainable recurrent color constancy network – the RCC-Net – which exploits convolutional LSTMs and a simulated sequence to learn compositional representations in space and time ...

It is both true and efficient that sensorineural systems respond to change and little else. Perceptual systems do not record absolute level be it loudness, pitch, brightness, or color. This fact has been demonstrated in every sensory domain. For example, the visual system is remarkable at maintaining color constancy over widely varying illumination ...

This article proposes an account of color constancy based on an examination of the relevant scientific literature. Differences in experimental settings and task instructions that lead to variation in subject performance are given particular attention. Based on the evidence discussed, the core of the proposal made is that there are two different forms ...

A sensor located inside a digital camera is only able to measure the light that is reflected by an object. The reflected light varies with the spectral power distribution of the illuminant. Hence, images taken with a digital camera may show a strong color cast if an incorrect white balance setting has been chosen.

The ability to compute color constant descriptors of objects in view irrespective of the light illuminating the scene is called color constancy. We have used genetic programming to evolve an algorithm for color constancy. The algorithm runs on a grid of processing elements.
