Extraction of optical properties from hyperspectral images by Monte Carlo light propagation model

摘要

In this paper, diffuse reflectance hyperspectral images of a light beam propagating through a semi-infinite homogeneous layer were simulated by a modified version of the open source Monte Carlo (MC) for multi-layered tissues. Subsequently, the optical properties in terms of absorption and reduced scattering coefficients were extracted from the simulated hyperspectral images by an inverse MC model based on a criterion function that exploits the spatially resolved information of hyperspectral images. The method was validated on real hyperspectral images of turbid phantoms with exactly defined optical properties.
