CanonSwap, as a framework for academic research, realizes three groundbreaking advantages at the technical level:
- Timing Stability: Eliminate the inter-frame jitter problem caused by the traditional method through the motion-appearance decoupling mechanism in the canonical space, and its optical flow analysis shows that the displacement error of neighboring frame feature points is reduced by 83%
- Dynamic fidelity: Individually processed motion feature channels ensure that micro-expressions (e.g., mouth twitching) and macro-movements (e.g., hair tossing) of the original video are retained by 100%.
- local accuracy: The PIM module employs a spatial attention mechanism to achieve sub-pixel level (0.3px) identity fusion accuracy at 256×256 resolution
Comparison test data shows that CanonSwap is 62% better than mainstream apps in FID (visual quality) index, and 75% lower than the error rate in SyncNet (mouth synchronization) test. these technical features make it especially suitable for film and TV level demanding face-swap scenes.
