An evaluation of the relationship between impression and the physical properties of human skin

The visual expression of a surface quality of human skin is required in a wide range of fields, such as in cosmetics industry. It is much harder, however, to generate intuitively and accurately a computer graphics (CG) image of human skin that has a desired impression without professional knowledge and skills because of its complex physical properties. It is necessary to model the linkage between the visual impressions and physical properties of human skin in order to effectively determine parameters for the generation of CG images.
