报告摘要：

Images captured in real-world environments often suffer from diverse degradation patterns governed by underlying physical processes, such as motion blur, haze, rain, and low illumination, which lead to undesired contrast loss and appearance distortions. With the rapid development of deep generative image models, numerous image restoration methods have been proposed to effectively alleviate these degradations. As most deep restoration approaches rely on supervised learning, their performance strongly depends on the diversity and representativeness of the training data. However, for many real-world degradations—such as rain, haze, and motion blur—collecting paired degraded and clean images is expensive and often impractical, severely limiting the coverage of available training datasets. These data acquisition challenges restrict the effectiveness and generalization ability of existing restoration models. In this talk, we will present how physics-based models can be leveraged both to enrich training datasets with realistic degradation distributions and to be integrated into diffusion-based restoration frameworks. By incorporating physics-informed priors, the performance of generative restoration models can be substantially enhanced. Representative results will be demonstrated on image dehazing and deblurring tasks.
