An Open Problem on Sparse Representations in Unions of Bases
Yi Shen, Chenyun Yu, Yuan Shen +1
We consider sparse representations of signals from redundant dictionaries which are unions of several orthonormal bases. The spark introduced by Donoho and Elad plays an important…
A remark on the Restricted Isometry Property in Orthogonal Matching Pursuit
Qun Mo, Yi Shen
This paper demonstrates that if the restricted isometry constant of the measurement matrix satisfies then a greedy algorithm cal…
Sparse Signals Recovery from Noisy Measurements by Orthogonal Matching Pursuit
Yi Shen, Song Li
Recently, many practical algorithms have been proposed to recover the sparse signal from fewer measurements. Orthogonal matching pursuit (OMP) is one of the most effective algorith…
Shearlet frames with short support
Song Li, Yi Shen
Compactly supported shearlets have been studied in both theory and applications. In this paper, we construct symmetric compactly supported shearlet systems based on pseudo splines…
Remarks on the Restricted Isometry Property in Orthogonal Matching Pursuit algorithm
Qun Mo, Yi Shen
This paper demonstrates theoretically that if the restricted isometry constant of the compressed sensing matrix satisfies then a greedy…
Wavelets and framelets from dual pseudo splines
Yi Shen, Song Li
Dual pseudo splines constitute a new class of refinable functions with B-splines as special examples, which was introduced in \cite{DHSS}. In this paper, we shall construct Riesz w…
