FaceLift: New SOTA in 2D Landmarks

Curiosity: How can we learn 3D landmarks from 2D annotations without 3D datasets? What happens when we combine 3D-aware GANs with volumetric consistency?

FaceLift is Flawless AIโ€™s novel semi-supervised approach that learns 3D landmarks by directly lifting hand-labeled 2D landmarks. This method ensures better definition alignment without needing 3D landmark datasets.

  3. Volumetric Consistency: 3D ViT ensures spatial coherence
  4. Alignment: 3D landmarks aligned with 2D ground truth

Advantages:

  • โœ… No 3D landmark datasets needed
  • โœ… Better definition alignment
  • โœ… SOTA performance
  • โœ… Handles visible landmarks effectively

Key Takeaways

Retrieve: FaceLift demonstrates that 3D landmarks can be learned from 2D annotations using 3D-aware GANs and volumetric consistency, achieving SOTA without 3D datasets.

Innovate: By combining semi-supervised learning, 3D-aware priors, and volumetric consistency, FaceLift enables accurate 3D landmark estimation from 2D annotations, opening new possibilities for face analysis.
