Codeformer is a face restoration algorithm developed by researchers at Nanyang Technological University to improve old photos and fix issues in AI-generated faces.
The model uses a unique Codebook Lookup Transformer architecture, outperforming previous methods like GFPGAN, and can handle various face degradation types, producing natural-looking results.
Codeformer takes an image as input and outputs a restored, high-quality version of the face, supporting optional features like upscaling, face upsampling, background enhancement, and fidelity control.
The model's capabilities include robustly restoring faces in images and enhancing face quality, making it useful for improving image quality and addressing face-related issues.
