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.
