X-Dyna Overview
X-Dyna is an open source dynamic portrait animation generation project developed by ByteDance, based on advanced zero-sample diffusion technology to achieve.
Its core function is to drive the facial expression and body movement of the video, so that the static portrait photo "live", to generate realistic dynamic video effects.
Key Features
- Dynamic Portrait Animation Generation: Converts a single still portrait into a video with expressions and body movements
- transfer of facial expression: Accurately capture and transfer micro-expressions in drive videos
- zero-sample learning: Adapt to new faces without pre-training
- Multidimensional quality assessment: Provide professional evaluation indicators such as DTFVD, Face-Cos, etc.
Technical characteristics
The project seamlessly integrates the appearance context of the reference image into the spatial attention mechanism of the diffusion model through an innovative dynamic adapter module, thus preserving more details. Compared with traditional methods, X-Dyna provides significant improvement in terms of movement naturalness and expression richness.
