D Cheng, DK Prasad, MS Brown - Journal of the Optical Society of …, 2014 - opg.optica.org
Color constancy is a well-studied topic in color vision. Methods are generally categorized as
(1) low-level statistical methods,(2) gamut-based methods, and (3) learning-based methods …

Estimation of illuminants from projections on the planckian locus

B Mazin, J Delon, Y Gousseau - IEEE Transactions on Image …, 2015 - ieeexplore.ieee.org
This paper introduces a new approach for the automatic estimation of illuminants in a digital
color image. The method relies on two assumptions. First, the image is supposed to contain …

Illumination estimation based on a weighted color distribution

X Zhang, S Yue, R Gong, Q Li - Optik, 2019 - Elsevier
Based on the observation that whitish surfaces are perhaps a better indicator of the color of
the illuminant than strongly colored surfaces, we propose a new illumination estimation …
