X Dyna
Overview :
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.
Target Users :
X-Dyna is designed for individuals and teams that require efficient generation of high-quality human image animations, such as in animation production, video effects, and virtual reality. It quickly transforms static images into lively animations, enhancing creative efficiency, saving time and costs, while delivering highly realistic effects to meet users' demands for high-quality animation and expressiveness.
Use Cases
Transform a static portrait photo into an animation that changes according to the movements in the driving video.
Generate facial expressions and body movements for virtual characters that match the driving video.
Quickly create realistic dynamic character animations for visual effects, enhancing the overall impact.
Features
Zero-shot animation generation: Transfer movements from a driving video to a single image without additional training.
Dynamic detail enhancement: Preserve the motion module's detail generation capability through the Dynamics-Adapter module.
Facial expression transfer: Capture and precisely transfer identity-independent facial expressions.
Scene dynamic fusion: Generate dynamic effects that are consistent with the surrounding environment.
Diverse data training: Learn natural dynamics from mixed datasets of human and scene videos.
High-quality animation output: Generate highly realistic and expressive animations.
No post-processing required: All samples are directly generated by the model without any post-processing steps.
How to Use
Visit the X-Dyna project page to access relevant resources and code.
Prepare a human image that needs to be animated as input.
Select a driving video that includes the desired actions and expressions.
Use the X-Dyna model to transfer movements from the driving video to the input image, generating the animation.
Adjust model parameters as needed to optimize animation effects.
