VASA-1 - Microsoft Research
VASA-1, introduced by a group of researchers, is a cutting-edge framework designed for real-time generation of lifelike talking faces from a single static image and an accompanying speech audio clip. The model, named VASA-1, excels in producing highly synchronized lip movements with audio while also capturing a broad range of facial expressions and natural head movements that enhance the sense of realism and liveliness in the generated faces. Central to this innovation is the holistic model for facial dynamics and head movement, which operates within a unique latent space crafted from video data.
Extensive testing and new metrics have confirmed VASA-1's superiority over existing methods in multiple aspects. Remarkably, VASA-1 supports streaming of high-quality 512x512 video at up to 40 frames per second with minimal latency, paving the way for engaging, real-time interactions with avatars that truly mimic human conversational patterns.
Real-Time Generation: Supports the streaming of lifelike avatars at up to 40 FPS.
High-Quality Video: Delivers 512x512 high video quality with realistic facial expressions.
Latent Space Modeling: Utilizes a face latent space for holistic facial dynamics and head movement generation.
Audio Synchronization: Produces lip movements that are perfectly synced with the given audio clip.
Extensive Experimentation: Outperforms previous methods and is validated by a set of new metrics.
