Overview of LivePortrait
LivePortrait is an advanced AI-driven portrait animation framework developed by Kuaishou Technology, in collaboration with the University of Science and Technology of China and Fudan University. Unlike mainstream diffusion-based methods, LivePortrait leverages an implicit-keypoint-based framework for creating lifelike video animations from a single source image. This approach balances computational efficiency and controllability, making it a practical tool for various applications.
How LivePortrait Generates AI Content
LivePortrait's animation process involves a two-stage training pipeline:
First Stage: Base Model Training
In the first stage, the base model is trained from scratch. This stage involves optimizing the appearance extractor, the motion extractor, the warping module, and the decoder. These components work together to extract and synthesize the appearance and motion from the source image and driving video, respectively.
Second Stage: Stitching and Retargeting Modules Training
In the second stage, the previously trained components are frozen, and the focus shifts to optimizing the stitching and retargeting modules. These modules enhance the animation's quality by providing finer control over specific facial features such as eyes and lips, allowing for more detailed and expressive animations.
Key Features of LivePortrait
Efficiency and Speed
LivePortrait achieves remarkable generation speed, reaching 12.8ms per frame on an RTX 4090 GPU using PyTorch. This efficiency makes it suitable for real-time applications.
High-Quality Animations
By scaling up the training data to about 69 million high-quality frames and adopting a mixed image-video training strategy, LivePortrait ensures superior animation quality and generalization.
Advanced Controllability
The stitching and retargeting modules allow precise control over facial features, enabling detailed animations. Users can control the extent of eyes and lip movements, enhancing the realism of the generated videos.
Versatility
LivePortrait supports various styles including realistic, oil painting, sculpture, and 3D rendering. This versatility makes it suitable for a wide range of applications from creative content to professional video production.
