Abstract
With the recent progress in various imaging systems, facial skin color reproduction becomes increasingly important. Human skin is a very turbid medium with multilayered structure. Various pigments such as melanin and hemoglobin are contained in the skin. Slight changes in structure and pigment construction produce rich skin color appearance. In this research, we reproduce various facial skin color by changing amount of melanin and hemoglobin components. The spatial distributions of melanin and hemoglobin components in the skin are separated by independent component analysis of skin color. The separated components are synthesized to reproduce the various facial color images by changing amount of separated pigments. The synthesized images are evaluated subjectively by comparing with the original facial image. Correlation maps are analyzed between appearance of facial color images and amount of melanin and hemoglobin components in the facial skin. From these analysis, we could find that how changes of melanin or hemoglobin components influence the appearance of facial color image.
