Multispectral Image Acquisition and Simulation of Illuminant Changes

Abstract

In this chapter we describe a system for the acquisition of multispectral images using a CCD camera with carefully selected optical filters. We further present an application where the acquired multispectral images are used to simulate the image of a scene as it would have appeared under a given illuminant. For this application, the use of multispectral images is found to yield a much higher accuracy compared to traditional methods using only three-channel colour images.
