Domain Adaptation of Mismatched Proximal Denoiser for Plug-and-Play Image Reconstruction

Guixian Xu, Jinglai Li, Junqi Tang

Plug-and-play proximal gradient descent (PnP-PGD) enables flexible image reconstruction by using denoisers as implicit priors. In practice, these denoisers are often deployed outsi…
