WebNov 1, 2016 · Mutual incoherence 1. Introduction The theory of compressed sensing (CS) [5], [7], [10], [29] ensures that a small number of linear samples suffice to capture all the information in a sparse vector and that we can recover the sparse vector from these samples using efficient algorithms. WebCompressed sensing (CS) has shown a sparsity-promoting convex program allows image reconstruction from a reduced data set when using the appropriate sampling. The development of a pseudo-random center placement (CP) O-space CS approach optimizes incoherence through SEM field modulation to reconstruct an image with reduced error.
