High-resolution imaging with compositional and chemical sensitivity is crucial for a wide
range of scientific and engineering disciplines. Although synchrotron X-ray imaging through …

Purpose MR parameter map** is one of clinically valuable MR imaging techniques.
However, increased scan time makes it difficult for routine clinical use. This article aims at …

We introduce a method to recover a continuous domain representation of a piecewise
constant two-dimensional image from few low-pass Fourier samples. Assuming the edge set …

In this article, we provide a detailed review of recent advances in the recovery of continuous-
domain multidimensional signals from their few nonuniform (multichannel) measurements …

It is a classic problem to estimate continuous-time sparse signals, like point sources in a
direction-of-arrival problem, or pulses in a time-of-flight measurement. The earliest …

Fourier-domain structured low-rank matrix priors are emerging as powerful alternatives to
traditional image recovery methods such as total variation and wavelet regularization. These …

This paper addresses the problem of sampling non-bandlimited signals within the Finite
Rate of Innovation (FRI) setting. We had previously shown that, by using sampling kernels …

Purpose Magnetic resonance imaging (MRI) artifacts are originated from various sources
including instability of an magnetic resonance (MR) system, patient motion, inhomogeneities …

A spatially distributed network contains a large amount of agents with limited sensing, data
processing, and communication capabilities. Recent technological advances have opened …

Recent theory of map** an image into a structured low-rank Toeplitz or Hankel matrix has
become an effective method to restore images. In this paper, we introduce a generalized …
