Joint-Sparse-Blocks Regression for Total Variation Regularized Hyperspectral Unmixing
Sparse unmixing has attracted much attention in recent years. It aims at estimating the fractional abundances of pure spectral signatures in mixed pixels in hyperspectral images. To exploit spatial-contextual information present in the scene, the total variation (TV) regularization is incorporated i...
