StyleRig: Rigging StyleGAN for 3D Control over Portrait Images

Tewari, Ayush, Elgharib, Mohamed, Bharaj, Gaurav et al.

Understand

StyleGAN generates photorealistic portrait images of faces with eyes, teeth, hair and context (neck, shoulders, background), but lacks a rig-like control over semantic face parameters that are interpretable in 3D, such as face pose, expressions, and scene illumination.

  • Three-dimensional morphable face models (3DMMs) on the other hand offer control over the semantic parameters, but lack photorealism when rendered and only model the face interior, not other parts of a portrait image (hair, mouth interior, background).
  • We present the first method to provide a face rig-like control over a pretrained and fixed StyleGAN via a 3DMM.
  • A new rigging network, RigNet is trained between the 3DMM's semantic parameters and StyleGAN's input.
