"Live Portrait is an innovative AI-driven tool that transforms still images into lively, animated portraits. Utilizing advanced stitching technology, this versatile application allows users to create animations in various styles and sizes. With the ability to generate realistic facial expressions, fluid head movements, and precise lip synchronization from just one photo, Live Portrait offers robust video-to-video face animation and editing features. Users have fine-tuned control over animations, including eye movements and lip positions, enabling nuanced emotional expressions. The underlying technology leverages an implicit-keypoint-based framework that optimizes computational efficiency and user control, thanks to an enhanced mixed image-video training approach and a sophisticated network architecture. Additionally, improved motion transformation and optimization objectives, along with stitching and retargeting modules, grant users exceptional control over their animations. This tool is ideal for applications like self or cross re-enactments, transforming still images into animated portraits, portrait video editing, and detailed control over eye and lip movements. Moreover, Live Portrait has the potential to be adapted for animating animal portraits as well. Developed through collaboration between Kuaishou Technology, the University of Science and Technology of China, and Fudan University, Live Portrait is available for free trial, potentially transforming the landscape of portrait animation creation."
