Fast Single Image Dehazing via Multilevel Wavelet Transform based Optimization
Jiaxi He, Frank Z. Xing, Ran Yang +1
The quality of images captured in outdoor environments can be affected by poor weather conditions such as fog, dust, and atmospheric scattering of other particles. This problem can…
Iterative Bayesian Reconstruction of Non-IID Block-Sparse Signals
Mehdi Korki, Jingxin Zhang, Cishen Zhang +1
This paper presents a novel Block Iterative Bayesian Algorithm (Block-IBA) for reconstructing block-sparse signals with unknown block structures. Unlike the existing algorithms for…
Parallel MRI Reconstruction by Convex Optimization
Cishen Zhang, Ifat-Al Baqee
In parallel magnetic resonance imaging (pMRI), to find a joint solution for the image and coil sensitivity functions is a nonlinear and nonconvex problem. A class of algorithms rec…
A discretization-free sparse and parametric approach for linear array signal processing
Zai Yang, Lihua Xie, Cishen Zhang
Direction of arrival (DOA) estimation in array processing using uniform/sparse linear arrays is concerned in this paper. While sparse methods via approximate parameter discretizati…
A Convex Optimization Approach to pMRI Reconstruction
Cishen Zhang, Ifat Al Baqee
In parallel magnetic resonance imaging (pMRI) reconstruction without using estimation of coil sensitivity functions, one group of algorithms reconstruct sensitivity encoded images…
Robust Compressive Phase Retrieval via L1 Minimization With Application to Image Reconstruction
Zai Yang, Cishen Zhang, Lihua Xie
Phase retrieval refers to a classical nonconvex problem of recovering a signal from its Fourier magnitude measurements. Inspired by the compressed sensing technique, signal sparsit…
