EchoMimicV2: Towards Striking, Simplified, and Semi-Body Human Animation

Understand

Recent work on human animation usually involves audio, pose, or movement maps conditions, thereby achieves vivid animation quality.

• However, these methods often face practical challenges due to extra control conditions, cumbersome condition injection modules, or limitation to head region driving.
• Hence, we ask if it is possible to achieve striking half-body human animation while simplifying unnecessary conditions.
• To this end, we propose a half-body human animation method, dubbed EchoMimicV2, that leverages a novel Audio-Pose Dynamic Harmonization strategy, including Pose Sampling and Audio Diffusion, to enhance half-body details, facial and gestural expressiveness, and meanwhile reduce conditions redundancy.
