Mimicmotion
Overview :
Developed jointly by Tencent and Shanghai Jiao Tong University, MimicMotion is a high-quality human motion video generation model. This model achieves controllability in the video generation process through confidence-aware pose guidance, improving temporal smoothness and reducing image distortion. Employing an advanced image-to-video diffusion model combined with a spatiotemporal U-Net and PoseNet, it can generate videos of arbitrary length with high quality based on pose sequence conditions. MimicMotion significantly outperforms prior methods in several aspects, including hand generation quality and accurate adherence to reference poses.
Target Users :
MimicMotion is targeted towards video creators, animators, and AI researchers. This technology enables them to generate high-quality video content, particularly in scenarios requiring complex human motion and temporal consistency. Applications include filmmaking, virtual reality experiences, game animation, and AI research.

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.
