Liveportrait
Overview :
LivePortrait is a human animation generation model based on an implicit keypoint framework. It synthesizes realistic videos by using a single source image as a reference for appearance and acquiring actions (e.g., facial expressions and head poses) from driving videos, audio, text, or generation. The model effectively balances computational efficiency and controllability, and significantly improves the generation quality and generalization capability through expanded training data, a hybrid image-video training strategy, upgraded network architecture, and the design of better motion transfer and optimization objectives.
Target Users :
LivePortrait targets animators, game developers, and post-production professionals who need to rapidly generate realistic human animations for character design, advertisement creation, or other visual media projects. Due to its efficiency and controllability, it is particularly suitable for professionals who require quick iterations and precise control over animation details.
Use Cases
Animators use LivePortrait to quickly generate character animations for film previews.
Game developers utilize LivePortrait to create lifelike facial expressions for game characters.
Advertisement teams use LivePortrait to generate engaging animated human figures for product advertisements.

Animate Anyone
Animate Anyone aims to generate character videos from static images driven by signals. Leveraging the power of diffusion models, we propose a novel framework tailored for character animation. To maintain consistency of complex appearance features present in the reference image, we design ReferenceNet to merge detailed features via spatial attention. To ensure controllability and continuity, we introduce an efficient pose guidance module to direct character movements and adopt an effective temporal modeling approach to ensure smooth cross-frame transitions between video frames. By extending the training data, our method can animate any character, achieving superior results in character animation compared to other image-to-video approaches. Moreover, we evaluate our method on benchmarks for fashion video and human dance synthesis, achieving state-of-the-art results.
