Abstract

In this study, we propose a digital color imaging algorithm for estimating object colors by removing an illuminant color from an input scene to achieve color constancy. This method is for restoring surface spectral reflectance using a set of two images: a first image is taken under unknown illuminant, and a second one is taken under known illuminant in addition to the unknown illuminant. Simulation results showed that this algorithm successfully removes the effect of the illuminant color and achieves color constancy at a practical computational cost
