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…
Restricted -Isometry Properties Adapted to Frames for Nonconvex -Analysis
Junhong Lin, Song Li
This paper discusses reconstruction of signals from few measurements in the situation that signals are sparse or approximately sparse in terms of a general frame via the -anal…
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…
