WebDec 17, 2015 · Recently, it has been shown that incoherence is an unrealistic assumption for compressed sensing when applied to many inverse problems. Instead, the key property that permits efficient recovery in such problems is the so-called local incoherence. Similarly, the standard notion of sparsity is also inadequate for many real-world problems. In particular, … Web2.2. Incoherence Compressed sensing is based on a choice of a sensing basis ˚relative to representation basis, which use an incoherence property for measure the correlation between vectors from each basis.
