Fast Fourier Color Constancy

CVPR 2017 google/ffcc

We present Fast Fourier Color Constancy (FFCC), a color constancy algorithm which solves illuminant estimation by reducing it to a spatial localization task on a torus.

FC4: Fully Convolutional Color Constancy With Confidence-Weighted Pooling

CVPR 2017 yuanming-hu/fc4

However, the patch-based CNNs that exist for this problem are faced with the issue of estimation ambiguity, where a patch may contain insufficient information to establish a unique or even a limited possible range of illumination colors.

Conditional GANs for Multi-Illuminant Color Constancy: Revolution or Yet Another Approach?

15 Nov 2018acecreamu/angularGAN

Non-uniform and multi-illuminant color constancy are important tasks, the solution of which will allow to discard information about lighting conditions in the image.

COLOR CONSTANCY SHADOW DETECTION AND REMOVAL

What Else Can Fool Deep Learning? Addressing Color Constancy Errors on Deep Neural Network Performance

ICCV 2019 mahmoudnafifi/WB_color_augmenter

There is active research targeting local image manipulations that can fool deep neural networks (DNNs) into producing incorrect results.

Artificial Color Constancy via GoogLeNet with Angular Loss Function

20 Nov 2018acecreamu/color-constancy-googlenet

Color Constancy is the ability of the human visual system to perceive colors unchanged independently of the illumination.

When Color Constancy Goes Wrong: Correcting Improperly White-Balanced Images

CVPR 2019 mahmoudnafifi/WB_sRGB

The challenge lies not in identifying what the correct white balance should have been, but in the fact that the in-camera white-balance procedure is followed by several camera-specific nonlinear color manipulations that make it challenging to correct the image's colors in post-processing.

Color Constancy by Reweighting Image Feature Maps

25 Jun 2018QiuJueqin/Reweight-CC

In this study, a novel illuminant color estimation framework is proposed for color constancy, which incorporates the high representational capacity of deep-learning-based models and the great interpretability of assumption-based models.

Cascading Convolutional Color Constancy

24 Dec 2019yhlscut/C4

Regressing the illumination of a scene from the representations of object appearances is popularly adopted in computational color constancy.

Semantic White Balance: Semantic Color Constancy Using Convolutional Neural Network

1 Feb 2018mahmoudnafifi/Semantic-Color-Constancy-Using-CNN

The goal of computational color constancy is to preserve the perceptive colors of objects under different lighting conditions by removing the effect of color casts caused by the scene's illumination.

COLOR CONSTANCY SEMANTIC SEGMENTATION

Revisiting Gray Pixel for Statistical Illumination Estimation

22 Mar 2018yanlinqian/Mean-shifted-Gray-Pixel

We present a statistical color constancy method that relies on novel gray pixel detection and mean shift clustering.
