Analyzing the Components of Dark Circle by Nonlinear Estimation of Chromo- phore Concentrations and Shading

抄録

This paper aims to apply nonlinear estimation of chromophore concentrations: melanin, oxy-hemoglobin, deoxy-hemoglobin and shading to the real hyperspectral image of skin. Skin reflectance is captured in the wavelengths between 400nm and 700nm by hy- perspectral scanner. Five-band wavelengths data are selected from skin reflectance. By using the cubic function which obtained by Monte Carlo simulation of light transport in multi-layered tissue, chromophore concentrations and shading are determined by min- imize residual sum of squares of reflectance. The dark circles are analyzed by the proposed method, and dominant component of the dark circles is found by the subjective evaluation for the modulated images.
