Estimating Illumination Chromaticity via Support Vector Regression

Funt, B., Xiong, W., "Estimating Illumination Chromaticity via Support Vector Regression" 12th Color Imaging Conference - Color Science, Systems & Applications, The SunBurst Resort Scottsdale, AZ, pp 47-52, November 2004


The technique of support vector regression is applied to the problem of estimating the chromaticity of the light illuminating a scene from a color histogram of an image of the scene. Illumination estimation is fundamental to white balancing digital color images and to understanding human color constancy. Under controlled experimental conditions, the support vector method is shown to perform better than the neural network and color by correlation methods.
