  • 3 min read

In the burgeoning field of digital humans, Alibaba, in collaboration with Beijing University of Posts and Telecommunications, has unveiled a groundbreaking project named FantasyPortrait. This initiative employs an innovative Expression-augmented Diffusion Transform (DiT), achieving complex emotional expression and cross-identity expression migration in both single and multi-person scenarios, marking a significant breakthrough in digital human animation technology.

Revolutionizing Digital Human Animation: Alibaba's FantasyPortrait

FantasyPortrait's cutting-edge technology is built upon the Expression-augmented DiT, focusing on the generation and control of digital human animations. Capable of handling both single and multi-person scenarios with cross-identity expression migration, FantasyPortrait delivers high-fidelity reproduction of nuanced emotions, from subtle smiles to intense anger, significantly enhancing the realism and expressiveness of digital human animations.

What sets FantasyPortrait apart is its ability to independently control the expressions of multiple characters in multi-person scenarios, avoiding the common issue of expression interference seen in traditional techniques. This allows for the depiction of distinct expressions by different digital humans within the same scene, without interference, providing robust technical support for film production, virtual reality, and game development.

Flexibility is at the heart of FantasyPortrait's appeal. Not only does it support the animation generation of human characters, but it also extends to animal imagery, offering creative content creators a wider range of possibilities. Additionally, the project features audio-driven capabilities, enabling users to drive the expressions and movements of digital humans through audio input, synchronizing the animation effects with the audio rhythm.

The multimodal driving capability of FantasyPortrait opens up broad application prospects in the fields of virtual anchors, short video content creation, and interactive entertainment. Whether it's crafting virtual idols or generating personalized animations, FantasyPortrait offers efficient and high-quality solutions.

FantasyPortrait's commitment to open-sourcing its code and models in the future will further lower the barriers for developers to access cutting-edge digital human technology, empowering the global developer community to explore and apply this technology. Alibaba's continuous investment in AI open-source fields has garnered widespread acclaim, and the open-sourcing plan of FantasyPortrait will undoubtedly further solidify its leading position in the digital human technology domain.

The collaboration between Alibaba and Beijing University of Posts and Telecommunications exemplifies the integration of industry, academia, and research. The university's profound academic foundation in communications and AI, combined with Alibaba's engineering capabilities, provides solid support for the development of FantasyPortrait.

FantasyPortrait's launch signifies a significant advancement in emotional expression and multi-character interaction within digital human technology. Its potential applications in film production, virtual reality, and game development are highly anticipated. For instance, film production teams can utilize FantasyPortrait to quickly generate multi-character animation scenes, reducing production costs; game developers can create more immersive character interaction experiences through its audio-driven features.

FantasyPortrait's innovation not only elevates the quality of digital human animations but also provides content creators with more flexible tools. As the technology matures further, FantasyPortrait is poised to become a benchmark in the digital human field, propelling the industry to new heights.

For those interested in digital human animation, the upcoming release of FantasyPortrait's code is something to look forward to, offering the opportunity to experience the charm of this technology firsthand. Stay tuned for the latest updates and open-source developments on this project for more cutting-edge insights.
