Parameterization using Fourier series expansion of the diffuse reflectance of human skin to vary the concentration of the melanocytes

摘要

Human skin has been studied in numerous investigations, given the interest in knowing information about physiology, morphology and chemical composition. These parameters can be determined using non invasively optical techniques in vivo, such as the diffuse reflectance spectroscopy. The human skin color is determined by many factors, but primarily by the amount and distribution of the pigment melanin. The melanin is produced by the melanocytes in the basal layer of the epidermis. This research characterize the spectral response of the human skin using the coefficients of Fourier series expansion. Simulating the radiative transfer equation for the Monte Carlo method to vary the concentration of the melanocytes (f_(me)) in a simplified model of human skin. It fits relating the Fourier series coefficient a_0 with f_(me). Therefore it is possible to recover the skin biophysical parameter.
