What is LivePortrait?
LivePortrait is a state-of-the-art AI model designed for efficient portrait animation and video editing. Developed by researchers at Kuaishou Technology, it introduces innovative approaches to face reenactment with precise control over stitching and retargeting mechanisms. The model stands out for its ability to handle both single images and videos as source inputs, creating natural and high-quality animations.
Implementation Details
The model architecture consists of several key components: an Appearance Feature Extractor (0.84M parameters), Motion Extractor (28.12M parameters), SPADE Generator (55.37M parameters), and Warping Module (45.53M parameters). It also includes specialized Stitching and Retargeting Modules (0.23M parameters) for enhanced control over the animation process.
- Supports both CPU and GPU inference with optimized performance
- Implements auto-cropping for driving videos
- Includes motion template generation for privacy protection
- Features Gradio interface for easy deployment
Core Capabilities
