Goniospectral imaging of three-dimensional objects

We propose a method for extracting goniospectral information of three-dimen sional objects from multiband images obtained under several illuminants and reproducing the objects under various kinds of illuminants. Using the dich romatic reflection model, goniophotometric information of both diffuse comp onent and specular component is estimated from the images acquired under th e illuminant from several illumination directions. On the other hand, spect ral information is estimated from five band images using the minimum mean s quare error criterion. Experimental results using simple three-dimensional objects are presented to demonstrate the basic performance of the proposed method.
