WebMar 20, 2024 · For example, the authors in suggested optimizing the incoherence property, of the sensing matrix, based on a gradient alternating minimization approach. Even if the aforementioned optimization approaches improve the CS performance, they have some drawbacks. Firstly, their iterative behavior leads to a prohibitive computation time. WebApr 24, 2024 · The literature on compressive sensing (CS) frequently notes that CS relies on two principles: sparsity and incoherence. While I understand why the signal of interest should be sparse in some domain since CS relies on minimizing the norm, incoherence is much fuzzier to me. easiest 14er hikes in colorado

It is introduced in the context of matrix completion to ensure the singular vectors of are not too "sparse" in the sense that all coordinates of each singular vector are of comparable magnitude instead of just a few coordinates having significantly larger magnitudes.

WebThere is an incoherence property μ used in CS to measure the correlation between the sensing and representation bases; whereby low correlation enables signal reconstruction of sparse signals with fewer samples and high correlation makes it nearly impossible regardless of the sparsity of the signal.
