An analysis of reconstruction noise from undersampled 4D flow MRI
Lauren Partin, Daniele E. Schiavazzi, Carlos A. Sing Long
Novel Magnetic Resonance (MR) imaging modalities can quantify hemodynamics but require long acquisition times, precluding its widespread use for early diagnosis of cardiovascular d…
An Optimal Algorithm for Strict Circular Seriation
Santiago Armstrong, Cristóbal Guzmán, Carlos A. Sing-Long
We study the problem of circular seriation, where we are given a matrix of pairwise dissimilarities between objects, and the goal is to find a {\em circular order} of the objec…
Unbiased Risk Estimates for Singular Value Thresholding and Spectral Estimators
Emmanuel J. Candes, Carlos A. Sing-Long, Joshua D. Trzasko
In an increasing number of applications, it is of interest to recover an approximately low-rank data matrix from noisy observations. This paper develops an unbiased risk estimate--…
A single-photon sampling architecture for solid-state imaging
Ewout van den Berg, Emmanuel Candes, Garry Chinn +3
Advances in solid-state technology have enabled the development of silicon photomultiplier sensor arrays capable of sensing individual photons. Combined with high-frequency time-to…
