WebJun 17, 2010 · Incoherence plays an important role in CS and sparse signal approximation. Low-coherence guarantees that sparse recovery algorithms can exactly recover any sufficiently sparse signal and that this solution is unique. In CS, incoherence of the measurement matrix (related to the sampling in k – p space) is desired. WebIncoherent sampling is the fundamental requirement for a successful reconstruction using the CS theory. Incoherent sampling means that the aliasing artifacts caused by . k-space undersampling should be incoherent (i.e. noise like) in the sparsifying transform domain (12-14). Based on the CS
