Compressed Sensing

Il compressed sensing è una tecnica di risoluzione di un sistema indeterminato di equazioni lineari sotto le ipotesi che la soluzione del sistema sia S-sparsa, ovvero che in un'opportuna rappresentazione abbia al più S elementi non nulli. La strategia del compressed sensing consiste nel risolvere questo sistema tramite minimizzazione della norma l1 ...
