Imaging inverse problems involve reconstructing underlying im- ages from noisy observations. Traditional approaches often rely on hand- crafted priors, which can fail to capture the complexity of real-world data.The advent of pre-trained generative models has introduced new paradigms, offeringimprovedreconstructionsbylearningrichpriorsfromdata.Amongthese,diffusionmodelshaveemergedasapowerfulframework,achievingre- markablereconstructionperformanceacrossnumerousimaginginverseprob-lems. In this talk, I will provide an overview of the latest advancements in leveraging diffusion models to address imaging inverse problems, highlighting their technical innovations and practical applications.
成像逆问题涉及从噪声观测中重建底层图像。传统方法通常依赖于手工设计的先验，难以捕捉真实世界数据的复杂性。预训练生成模型的出现引入了新范式，通过从数据中学习丰富的先验，显著提升了重建效果。其中，扩散模型作为一种强大框架，在众多成像逆问题中取得了卓越的重建性能。本次报告将概述利用扩散模型解决成像逆问题的最新进展，重点介绍其技术创新与实际应用。
