Unsupervised CT Metal Artifact Reduction by Plugging Diffusion Priors in Dual Domains

1 code implementation31 Aug 2023 Xuan Liu, Yaoqin Xie, Songhui Diao, Shan Tan, Xiaokun Liang

In this paper, we propose an unsupervised MAR method based on the diffusion model, a generative model with a high capacity to represent data distributions.

Score Priors Guided Deep Variational Inference for Unsupervised Real-World Single Image Denoising

no code implementations ICCV 2023 Jun Cheng, Tao Liu, Shan Tan

By considering the deep variational image posterior with a Gaussian form, score priors are extracted based on easily accessible minimum MSE Non-$i. i. d$ Gaussian denoisers and variational samples, which in turn facilitate optimizing the variational image posterior.

Spectral Bayesian Uncertainty for Image Super-Resolution

no code implementations CVPR 2023 Tao Liu, Jun Cheng, Shan Tan

In this paper, we propose to quantify spectral Bayesian uncertainty in image SR. To achieve this, a Dual-Domain Learning (DDL) framework is first proposed.
