Deep Data Consistency: a Fast and Robust Diffusion Model-based Solver for Inverse Problems

1 code implementation17 May 2024 HanYu Chen, Zhixiu Hao, Liying Xiao

To address the challenges, we propose Deep Data Consistency (DDC) to update the data consistency step with a deep learning model when solving inverse problems with diffusion models.

Mitigating Data Consistency Induced Discrepancy in Cascaded Diffusion Models for Sparse-view CT Reconstruction

no code implementations14 Mar 2024 HanYu Chen, Zhixiu Hao, Lin Guo, Liying Xiao

This study introduces a novel Cascaded Diffusion with Discrepancy Mitigation (CDDM) framework, including the low-quality image generation in latent space and the high-quality image generation in pixel space which contains data consistency and discrepancy mitigation in a one-step reconstruction process.
