Fourier Ptychographic Microscopy via Alternating Direction Method of Multipliers [PDF]

open access: yesCells, 2022
Fourier ptychographic microscopy (FPM) has risen as a promising computational imaging technique that breaks the trade-off between high resolution and large field of view (FOV). Its reconstruction is normally formulated as a blind phase retrieval problem,

Quantitative susceptibility mapping using plug-and-play alternating direction method of multipliers [PDF]

open access: yesScientific Reports, 2022
Quantitative susceptibility mapping employs regularization to reduce artifacts, yet many recent denoisers are unavailable for reconstruction. We developed a plug-and-play approach to QSM reconstruction (PnP QSM) and show its flexibility using several ...
