The spatial distributions of melanin and hemoglobin in human skin are separated by independent component analysis of skin color image. It is our goal to apply these results for the estimation of preferred skin color in color reproduction and the evaluation of a face browned by the sun and diagnosis of a skin disease. In this paper, the principle of independent component analysis is described and it is also shown that the components of melanin and hemoglobin from skin color image can be separated both theoretically and experimentally.
