A Homogeneity-Based Multiscale Hyperspectral Image Representation for Sparse Spectral Unmixing

Several approaches have been proposed to solve the spectral unmixing problem in hyperspectral image analysis. Among them the use of sparse regression techniques aims to characterize the abundances in pixels based on a large library of spectral signatures known a priori. Recently, the integration of…
