Abstract
The spatial distributions of melanin and hemoglobin in human skin can be
determined by image-based skin chromophore analysis including independent
component analysis (ICA) of a skin color image. The separation is based on the
skin color model in the optical density domain to quantify the change in the
chromophores. In this paper, the analysis technique developed by Tsumura et al.
was applied to many skin images, and the distribution of skin chromophores, such
as melanin and hemoglobin, agreed well with the physiological knowledge. The
effectiveness of cosmetic products was also evaluated by observing the changes
in the amount of each chromophore. Finally a simulation to synthesize the
changes in skin chromophores was performed to demonstrate its validity.
