  1. Faces: Analysis and Synthesis Vision for GraphicsCSE 590SS, Winter 2001Richard Szeliski

  2. What can we do with faces? • Modeling (reconstruction): • manual[Pighin et al. 1998] • Automated[Zhang et al. 2000] Vision for Graphics

  3. What can we do with faces? • Analysis • principal components and deformation modes[Turk & Pentland 1991][Rowland & Perrett 1995][Guenter et al. 1998][Blanz & Vetter 1999] Vision for Graphics

  4. What can we do with faces? • Tracking and synthesis • tracking[Toyama 1998] • animation[Pighin et al. 1999][Buck et al. 2000] • Recognition[Turk & Pentland 1991; Lanitis et al. 1997] Vision for Graphics

  5. Synthesizing Realistic Facial Expressions from Photographs • Frederic Pighin Jamie Hecker Dani Lischinski v • David Salesin Richard Szeliski * • SIGGRAPH’98 Vision for Graphics

  6. Animated Face Modeling From Video Images Zhengyou Zhang, Zicheng Liu, Michael Cohen Vision Group & Graphics Group Microsoft Research

  7. Manipulating Facial Appearance through Shape and Color Duncan A. Rowland and David I. Perrett St Andrews University IEEE CG&A, September 1995

  8. Principal component analysis • Compute average faces (color and shape) • Compute deviations between male and female (vector and color differences) Vision for Graphics

  9. Deform shape and/or color of an input face in the direction of “more female” original shape color both Changing gender Vision for Graphics

  10. Enhancing gender • more same original androgynous more opposite Vision for Graphics

  11. Face becomes “rounder” and “more textured” and “grayer” original shape color both Changing age Vision for Graphics

  12. A Morphable Model For The Synthesis Of 3D Faces Volker Blanz Thomas Vetter SIGGRAPH’99

  13. Morphable model of 3D faces • Start with a catalogue of 200 3D Cyberware scans • Build a model of average shape and texture, and principal variations Vision for Graphics

  14. Divide face into 4 regions (eyes, nose, mouth, head) For each new prototype, find amount of deviation from the reference shape and texture. Morphable model of 3D faces Vision for Graphics

  15. Morphable model of 3D faces • Adding some variations Vision for Graphics

  16. Reconstruction from single image Vision for Graphics

  17. Modifying a single image Vision for Graphics

  18. Animating from a single image Vision for Graphics

  19. Resulting animation Vision for Graphics

  20. Tracking Face Orientation Kentaro Toyama Vision–Based Interaction Group Microsoft Research

  21. Resynthesizing Facial Animation through 3D Model-Based Tracking • Frédéric Pighin1 Richard Szeliski2 David Salesin1,2 1University of Washington 2Microsoft Research ICCV’99 Vision for Graphics

  22. Performance-Driven Hand-Drawn Animation Ian Buck Adam Finkelstein Charles Jacobs Allison Klein David H. Salesin Joshua Seims Richard Szeliski Kentaro Toyama

  23. Go from video to “cartoon” Vision for Graphics

  24. Hand-drawn expressions Vision for Graphics

  25. Expression correspondence Vision for Graphics

  26. Morphing and tracking Vision for Graphics

  27. More examples Vision for Graphics

  28. Final animations Vision for Graphics
