X-Dyna is an innovative zero-shot human image animation generation technology that creates realistic and expressive dynamic effects by transferring facial expressions and body movements from a driving video to a single human image. This technology uses a diffusion model and integrates reference appearance context effectively into the diffusion model's spatial attention through the Dynamics-Adapter module, while maintaining the motion module's ability to synthesize smooth and complex dynamic details. It not only enables body posture control but also captures and precisely transfers identity-independent facial expressions through a local control module. Trained on mixed datasets of various human and scene videos, X-Dyna can learn physical human motions and natural scene dynamics, generating highly realistic and expressive animations.
