Paper Abstract

Colorimetric data are generally not enough sufficient to describe color appearance of materials. In this paper we propose to use a description of surface that takes into account texture and relief. The first problem encountered is to have a reliable description of color appearance after the calibration stage of the camera. To do that, we have used a simple and straightforward method based on a determination of a mapping transform from RGB to XYZ. We have used the co- occurrence color matrix to describe the texture of the material. Relief can be described as the 'apparition of texture with a rising light,' we have therefore studied the variation of the texture throughout the change of illumination angle.
