Underwater Single-Image Restoration with Transmission Estimation Using Color Constancy
Journal of Marine Science and Engineering, 2022 The issue of underwater image restoration was investigated in this paper. Specifically, the color constancy of a single image was used to estimate the transmission map (TM), which can be used in the image formation model to restore the underwater image ...

Color Constancy for Uniform and Non-Uniform Illuminant Using Image Texture
IEEE Access, 2019 Color constancy is the capability to observe the true color of a scene from its image regardless of the scene’s illuminant. It is a significant part of the digital image processing pipeline and is utilized when the true color of an object is ...

Fast Fourier Color Constancy [PDF]
2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2017 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. By operating in the frequency domain, FFCC produces lower error rates than the previous state-of-the-art by 13-20% while being 250-3000 times faster.

Deep Spatio-Temporal Illuminant Estimation Under Time-Varying AC Lights
IEEE Access, 2022 Artificial lights, which are powered by alternating current (AC), are ubiquitous nowadays. The intensity of these lights fluctuates dynamically depending on the AC power.

Color constancy using CNNs [PDF]
2015 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2015 In this work we describe a Convolutional Neural Network (CNN) to accurately predict the scene illumination. Taking image patches as input, the CNN works in the spatial domain without using hand-crafted features that are employed by most previous methods.

Perceptually Optimized Enhancement of Contrast and Color in Images
IEEE Access, 2018 In this paper, we propose perceptually optimized enhancement of contrast and color in images using just-noticeable-difference (JND) transform and color constancy.

A Novel Automatic White Balance Method for Color Constancy Under Different Color Temperatures
IEEE Access, 2021 The spectrum distribution of the light source between scenes is usually uniform in all scenes lit by a given light source per the color constancy assumption.

IEEE Access, 2021 For the imaging signal processing (ISP) pipeline of digital image devices, it is of high significance to remove undesirable illuminant effects and obtain color invariance, commonly known as ‘computational color constancy’.

Color Constancy Algorithm for Mixed-Illuminant Scene Images
IEEE Access, 2018 The intrinsic properties of the ambient illuminant significantly alter the true colors of objects within an image. Most existing color constancy algorithms assume a uniformly lit scene across the image.
