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 AIโs 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.
