Researchers have developed a novel physics-based framework for synthesizing realistic CCD noise in astronomical imaging. This approach models various noise sources, including photon shot noise, photo-response non-uniformity, and dark-current noise, to create abundant paired training datasets. The synthesized data enables supervised learning for denoising, which is crucial for scientific workflows where interpretability and accuracy are paramount. Experiments on real-world data demonstrate the framework's effectiveness in improving both photometric and scientific accuracy in astrophotography. AI
