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…
