Coupled dictionary learning for unsupervised change detection between multi-sensor remote sensing images
Vinicius Ferraris, Nicolas Dobigeon, Yanna Cavalcanti +2
Archetypal scenarios for change detection generally consider two images acquired through sensors of the same modality. However, in some specific cases such as emergency situations,…
