Show HN: Live Portrait AI: Create vivid and interesting portrait videos
Live Portrait Ai animation aims to synthesize realistic videos from a single source image, use them as appearance references, and extract motion from driving videos. Live Portrait Ai improves generation quality and generalization ability through 69 million training frames, mixed image video training, upgraded network architecture, and motion transformation targets. Compact implicit keypoints represent mixed shapes with stitching and redirection modules for controllability. Generating vivid and interesting videos for portrait has become so simple.
