LivePortrait 소개
LivePortrait is an advanced framework for portrait animation that transforms a single still image into a lifelike animated video. This technology leverages the implicit-keypoint-based framework to create a balance between computational efficiency and controllability. LivePortrait offers improved generalization, controllability, and efficiency compared to traditional diffusion-based methods. By expanding training data to approximately 69 million high-quality frames, adopting a mixed image-video training strategy, and upgrading network architecture, LivePortrait significantly enhances generation quality. Additionally, the introduction of stitching and retargeting modules allows for precise control over elements like eyes and lips. The system is optimized for performance, achieving impressive speeds of 12.8ms per frame on high-end GPUs. This makes LivePortrait ideal for practical applications in fields such as media production, social media, and virtual reality.
