Abstract
The spatial distributions of melanin and
hemoglobin in human skin are separated by
independent-component analysis of a skin
color image. The analysis is based on the
skin color model with three assumptions:
(1) Spatial variation of color in the skin
is caused by two pigments, melanin and hemoglobin;
(2) the quantities of the two pigments are
mutually independent spatially; and (3) linearity
holds among the quantities and the observed
color signals in the optical density domain.
The results of the separation agree well
with physiological knowledge. The separated
components are synthesized to simulate the
various facial color images by changing the
quantities of the two separated pigments.
