Face-vid2vid
In short: Face-vid2vid is a neural network approach for generating talking head videos by learning to transfer motion from a driving video to a source face using dense motion fields.
About Face-vid2vid
Face-vid2vid learns a one-shot model for face reenactment, where a single source image can be animated using motion extracted from a driving video. The approach decomposes motion into a dense motion field and uses learned keypoints to capture facial deformations. In the lip sync context, the driving signal can come from audio-predicted motion rather than a driving video, enabling audio-driven animation.
Face-vid2vid and its variants have been influential in the talking head generation space, demonstrating that high-quality video-to-video face translation is achievable with neural networks. The dense motion field approach ensures strong identity preservation.
