3d Morphable Face Model Fitting And Manipulation

via “head pose and gaze direction control”

LivePortrait — AI demo on HuggingFace

Unique: Decouples head pose from facial expression through a 3D morphable face model that separates rigid head transformation from non-rigid expression deformation, enabling independent control without expression artifacts during rotation

vs others: More geometrically accurate than 2D warping-based approaches and faster than full 3D face reconstruction because it uses a lightweight parametric face model with learned pose regression rather than iterative optimization
