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,

An Adaptive Alternating Direction Method of Multipliers
Journal of Optimization Theory and Applications, 2022 AbstractThe alternating direction method of multipliers (ADMM) is a powerful splitting algorithm for linearly constrained convex optimization problems. In view of its popularity and applicability, a growing attention is drawn toward the ADMM in nonconvex settings.

DQM: Decentralized Quadratically Approximated Alternating Direction Method of Multipliers [PDF]
IEEE Transactions on Signal Processing, 2015 This paper considers an optimization problem that components of the objective function are available at different nodes of a network and nodes are allowed to only exchange information with their neighbors. The decentralized alternating method of multipliers (DADMM) is a well-established iterative method for solving this category of problems; however ...

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.
