On Hyperspectral Super-Resolution

In this paper we will review seminal contributions of Prof. Jose Bioucas Dias for the improvement of the spatial resolution of hyperspectral images. Be it through the extension of pansharpening algorithms with spatial and spectral sparsity priors, using spectral unmixing, using a low-rank assumption from complementary multisource data, or by designing an edge-preserving convex formulation, Jose Bioucas Dias set up very solid and rigourous foundations for countless subsequent works.
