RIP sensing matrices construction for sparsifying dictionaries with application to MRI imaging
Jinn Ho, Wen-Liang Hwang, Andreas Heinecke
Practical applications of compressed sensing often restrict the choice of its two main ingredients. They may (i) prescribe using particular redundant dictionaries for certain class…
Deriving RIP sensing matrices for sparsifying dictionaries
Jinn Ho, Wen-Liang Hwang
Compressive sensing involves the inversion of a mapping , where , is a sensing matrix, and is a sparisfying dictionary. The restricte…
Unconstrained optimization using the directional proximal point method
Ming-Yu Chung, Jinn Ho, Wen-Liang Hwang
This paper presents a directional proximal point method (DPPM) to derive the minimum of any C1-smooth function f. The proposed method requires a function persistent a local convex…
Frame-based Sparse Analysis and Synthesis Signal Representations and Parseval K-SVD
Wen-Liang Hwang, Ping-Tzan Huang, Tai-Lang Jong
Frames are the foundation of the linear operators used in the decomposition and reconstruction of signals, such as the discrete Fourier transform, Gabor, wavelets, and curvelet tra…
