The first article in the series looked at GFPGAN, deep learning software for real-world face restoration. Real-ESRGAN and GFPGAN have been integrated into each other, but they are also individual projects from the same developer. Real-ESRGAN is a project that aims to create practical algorithms for general image/video restoration as opposed to face restoration.
