i3DMM Deep Implicit 3D Morphable Model of Human Heads

deep implicit 3D morphable model

• disentabgle geometry and color components
  • geometry: identity, expressions and hairstyle
  • color: identity and hairstyle
• SDF for surface representations
• data preprocessing: landmark annotation, head cropping
• mesh sampling for SDF training
  • additional points for eyes noses and mouth
• deform a reference shape
  • x —deformation network—> x in reference shape coordnate
  • enforce landmark color to be precise
  • L2 prior on latent codes
