论文摘要
许多历史人才只被旧，褪色，黑白照片捕获，这些照片由于早期相机的局限性和时间流逝而被扭曲。本文模拟了与现代摄像机的时光倒流，再到重新摄影著名的主题。与传统的图像恢复过滤器不同，该过滤器采用独立操作（例如Denoising，颜色化和超级分辨率），我们利用stylegan2框架将旧照片投射到现代高分辨率照片的空间中，从而在统一的框架中实现了所有这些效果。这种方法的一个独特挑战是保留原始照片中对象的身份和姿势，同时丢弃在低质量古董照片中经常看到的许多文物。我们与当前的最新修复过滤器的比较显示了各种重要历史人物的显着改善和令人信服的结果。
Many historical people were only ever captured by old, faded, black and white photos, that are distorted due to the limitations of early cameras and the passage of time. This paper simulates traveling back in time with a modern camera to rephotograph famous subjects. Unlike conventional image restoration filters which apply independent operations like denoising, colorization, and superresolution, we leverage the StyleGAN2 framework to project old photos into the space of modern high-resolution photos, achieving all of these effects in a unified framework. A unique challenge with this approach is retaining the identity and pose of the subject in the original photo, while discarding the many artifacts frequently seen in low-quality antique photos. Our comparisons to current state-of-the-art restoration filters show significant improvements and compelling results for a variety of important historical people.
