Compressive Sensing

Compressive Sensing (CS) er en teknik til signalanskaffelse og -rekonstruktion, der udnytter signalets sparsitet til at genvinde højopløselige signaler fra langt færre målinger, end hvad der kræves af Nyquist-samplingsteoremet. Udviklet af Emmanuel Candès, Justin Romberg og Terence Tao i 2006, udfordrer compressive sensing det traditionelle samplingparadigme ved at vise, at signaler med sparsomme repræsentationer kan rekonstrueres fra sub-Nyquist tilfældige målinger ved hjælp af ikke-lineær optimering.
