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

Cells, 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]

Scientific 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 ...

Joint Burst Denoising and Demosaicking via Regularization and an Efficient Alignment [PDF]

Journal of Artificial Intelligence and Data Mining, 2020
In this work, we show that an image reconstruction from a burst of individually demosaicked RAW captures propagates demosaicking artifacts throughout the image processing pipeline.
