Regularized inversion methods for image reconstruction are used widely due to their tractability and their ability to combine complex physical sensor models with useful regularity criteria. [] Key Method In this framework, the problem of MAP estimation in regularized inversion is replaced by the problem of solving these equilibrium equations, which can be approached in multiple ways, including as a fixed point problem that generalizes the ADMM approach used in the Plug-and-Play method.

An Online Plug-and-Play Algorithm for Regularized Image Reconstruction

A new online PnP algorithm based on the proximal gradient method (PGM) is introduced, which uses only a subset of measurements at every iteration, which makes it scalable to very large datasets.

Proximal denoiser for convergent plug-and-play optimization with nonconvex regularization

This paper shows that this gradient denoiser can actually correspond to the proximal operator of another scalar function, and exploits the convergence theory of proximal algorithms in the nonconvex setting to obtain convergence results for PnP-PGD and PNP-ADMM.

Regularization by Denoising via Fixed-Point Projection (RED-PRO)

This paper reformulates RED as a convex optimization problem utilizing a projection (RED- PRO) onto the fixed-point set of demicontractive denoisers, and establishes a novel unification of RED-PRO and PnP, while providing guarantees for their convergence to the globally optimal solution.

Fixed-Point and Objective Convergence of Plug-and-Play Algorithms

A novelty in this regard is that the analysis covers non-symmetric denoisers such as nonlocal means and almost any convex data-fidelity, and makes use of the convergence theory of averaged operators and a special inner product derived from the linear denoiser.

Distributed optimization with tunable learned priors for robust ptycho-tomography

This approach resolves issues by leveraging the nature of primal-dual splitting, yielding a very flexible plug-and-play image restoration method that is much more efficient than ADMMPnP with an inner loop and keeps the same efficiency in the case where the subproblem of ADM MPnP can be solved efficiently.
