Abstract
We propose a method for extracting goniospectral information of three-dimensional objects from multiband images obtained under several illuminants and reproducing the objects under various kinds of illuminants. Using the dichromatic reflection model, goniophotometric information of both diffuse component and specular component is estimated from the images acquired under the illuminant from several illumination directions. On the other hand, spectral information is estimated from five band images using the minimum mean square error criterion. Experimental results using simple three-dimensional objects are presented to demonstrate the basic performance of the proposed method.
