Presentation Transcript

  1. Global Alignment for Dynamic 3D Morphable Model Construction Rui Tang, Darren Coskerand Wenbin Li University of Bath

  2. Motivation • 3D Face Models • 3D Morphable Model [1] • Dynamic 3D FACS Dataset [2] • Corresponded Model for Facial Analysis • Speech analysis in 3D • Facial expression recognition

  3. Rigid Alignment and UV Projection • CPD (Coherent Point Drift) [3] vs ICP • UV Projection use Maya

  4. Local Non-Rigid Alignment

  5. Local Non-Rigid Alignment

  6. Global Non-Rigid Alignment Evaluation: Optical Flow VS TPS+OF

  7. Comparison between OF and TPS+OF

  8. Statistical Model • PCA Model • Low-Dim Representation

  9. Thank You!
