PnP-ADMM
An image restoration method that replaces the regularization term update in the ADMM optimization framework with a call to an off-the-shelf denoiser. It requires no explicit definition of a regularization term and allows pretrained denoising priors to be embedded directly.

When PnP-ADMM uses a diffusion model pretrained on large-scale natural images as a denoising prior, there exists a double distribution mismatch: target distribution mismatch (statistical difference between natural images and scientific images) and ADMM intermediate-state distribution mismatch (dual variable feedback distorts the denoiser input distribution).
