Abstract

As the linear mixture model cannot well characterize the resultant mixed spectra due to the complicated relations between different ground objects and the effect of atmospheric scattering,a nonlinear spectral mixture model-secondary scattering model is proposed in this paper.Computer simulated images and AVIRIS hyperspectral images of Cuprite district in America were tested,and the experimental results show that the decompostion result of the proposed model are much more precise than that of the traditional linear spectral mixture model.
