Abstract
In compressed sensing the matrices that satisfy the Restricted Isometry Property (RIP) play an important role. To date, however, very few results for designing such matrices are available. For applications such as multiplier-less data compression, binary sensing matrices are of interest. The present paper constructs deterministic and binary sensing matrices using Euler Squares. In particular, given a positive integer m different from p, p2 for a prime p, we show that it is possible to construct a binary sensing matrix of size m × c(mμ)2, where mu is the coherence parameter of the matrix and c ϵ [1,2). The matrices that we construct have small density (that is, percentage of nonzero entries in the matrix is small) with no function evaluation in their construction, which support algorithms with low computational complexity. Through experimental work, we show that our binary sensing matrices can be used for such applications as content based image retrieval. Our simulation results demonstrate that the Euler Square based CS matrices give better performance than their Gaussian counterparts. © 2016 IEEE.
