Abstract
In this article, we propose an effective method for gonio- spectral imaging of
paper and cloth samples under oblique illumination conditions. High resolution
gonio- spectral images are synthesized from a basic spectral image and gonio-
monochrome images. The method is based on gonio- spectral image fusion composed
of two components, conventional spatial fusion and geometrical fusion. The
proposed geometrical fusion synthesizes images at different geometries and is
introduced by modeling the optical reflection properties with a dichromatic
reflection model. The validity of this method is confirmed by gonio- spectral
measure-ments of paper samples, and experiments are performed on Japanese washi
paper and European cloth.
