This paper describes a method for the analysis and synthesis of human skin with color texture. The approach is based on the spatial frequency analysis of skin images. First, the observed color image is transformed into the frequency domain. Then, color texture patterns are separated on the spatial frequency. The original image is decomposed into four image components of (1) base color component, (2) regular surface texture component, (3) internal texture component and (4) local texture component. Moreover realistic images of the human skin under different conditions are synthesized by a linear combination of the four components. The color texture is particularly noticeable in the case of human palms. The reliability of the proposed method is shown in an experiment for palm images.
