Abstract
Mapping pigmentation in human skin is expected
to give useful information in reproducing
skin color and enhancing the ability to diagnose
various skin disease. In this research, maps
of melanin, oxy-hemoglobin and deoxy-hemoglobin
in skin are estimated from multi-channel
visible spectrum image by using an inverse
optical scattering technique. In the inverse
optical scattering technique, first of all,
a forward model of optical scattering is
built to simulate the spectral reflectance
of skin. Changing the variable parameters
in the forward model, we repeat the simulation
until the simulated spectral reflectance
matches with the spectral reflectance at
each pixel of the multi-spectral image. The
principle of the proposed estimation technique
was confirmed by imaging the human forearm
under conditions of the venous occlusion,
the venous and arterial occlusion, and by
imaging a slapped region of the human forearm.
