Estimating the Scene Illumination Chromaticity (original) (raw)

Abstract

ABSTRACT this paper we will assume that the chromaticity of the scene illumination is constant throughout the image, although its intensity may vary. The goal of a machine color constancy system will be taken to be the accurate estimation of the chromaticity of the scene illumination from a three-band, RGB digital color image of the scene. To achieve this goal, we developed a system based on a multilayer neural network. The network works with the chromaticity histogram of the input image and computes an estimate of the scene's illumination
