FOSS Advent Calendar - Door 7: Enhancing Images with Real-ESRGAN
Today we explore Real-ESRGAN, a powerful FOSS tool for upscaling and improving image quality.
The name stands for Enhanced Super-Resolution Generative Adversarial Networks, highlighting the AI-powered approach behind the magic.
Real-ESRGAN can take a low-resolution or slightly blurry image and enhance it, adding details that make it look sharper and more natural. It works via the command line, where you provide an input image and get an upscaled output image. You can instantly compare the results in your favorite image viewer, like EOG.
It’s perfect for nerds, FOSS enthusiasts, or anyone who wants to improve images without relying on commercial software.
Pro tip: try upscaling an old screenshot or a tiny meme, the results are often hilarious and impressive at the same time!
