From Blurry to Believable: Enhancing Low-quality Talking Heads with 3D Generative Priors

Researchers have developed 'SuperHead,' a framework that significantly improves low-quality video of talking faces. It uses a 3D generative model to create a high-resolution, animatable avatar with fine-grained details. The system ensures the avatar remains consistent and realistic during speech and expressions. Experiments show it outperforms existing methods, producing more believable results from poor source material for applications in virtual communication and entertainment.
