Paper Abstract

The coding of color images is usually confined to coding the color appearance for the illumination present at acquisition time. However, an exact reconstruction of a coded and transmitted document should produce the same color appearance as the original under variable illuminations. In this work we develop a representation of the necessary information to ensure such a color constancy. The only precondition is the absence of mutual illumination as a small but reasonable restriction to the type of illumination. The proposed image representation is developed to a complete image coder concept. Using this concept a hierarchical image description is achieved introducing a minimal color difference.
