Multi-color balance for color constancy

TL;DR

This paper introduces a new multi-color balancing method for color constancy that accurately corrects multiple target colors and outperforms traditional white-balancing techniques.

Contribution

The paper presents a novel n-color balancing approach that corrects multiple colors simultaneously, extending beyond white-balancing limitations.

Findings

Outperforms conventional white and multi-color balance methods

Accurately corrects multiple target colors

Demonstrates superior performance in experiments

Abstract

In this paper, we propose a novel multi-color balance adjustment for color constancy. The proposed method, called "n-color balancing," allows us not only to perfectly correct n target colors on the basis of corresponding ground truth colors but also to correct colors other than the n colors. In contrast, although white-balancing can perfectly adjust white, colors other than white are not considered in the framework of white-balancing in general. In an experiment, the proposed multi-color balancing is demonstrated to outperform both conventional white and multi-color balance adjustments including Bradford's model.
