Optimizing Paths for Adaptive Fly-Scan Microscopy: An Extended Version
Yu Lu, Thomas F. Lynn, Ming Du +2
In x-ray microscopy, traditional raster-scanning techniques are used to acquire a microscopic image in a series of step-scans. Alternatively, scanning the x-ray probe along a conti…
Sparse Signal Reconstruction for Overdispersed Low-photon Count Biomedical Imaging Using Total Variation
Yu Lu, Roummel F. Marcia
The negative binomial model, which generalizes the Poisson distribution model, can be found in applications involving low-photon signal recovery, including medical imaging. Recent…
Alternating Direction Method of Multipliers for Negative Binomial Model with The Weighted Difference of Anisotropic and Isotropic Total Variation
Yu Lu, Kevin Bui, Roummel F. Marcia
In many applications such as medical imaging, the measurement data represent counts of photons hitting a detector. Such counts in low-photon settings are often modeled using a Pois…
Negative Binomial Matrix Completion
Yu Lu, Kevin Bui, Roummel F. Marcia
Matrix completion focuses on recovering missing or incomplete information in matrices. This problem arises in various applications, including image processing and network analysis.…
