2. 2D image
Ground-truth 3D model
Reconstructed 3D model

3. Background of Face Modeling
what is Face Model?
the way people use to represent human faces
point cloud, mesh
a mapping from r-dimensional parameters to n-dimensional face surface (n>>r!)

4. Background of Face Modeling
why we do Face Modeling?
faces is the most important object in daily life
lots of applications, including face animation, computer game, etc.

5. How we do it in the PAST Geometric model
parameterize the changes of different parts
Physics model
muscle-model is used to simulate the expressions
Statistical model
collect face dataset, and use PCA to extract the principal modes

6. how we do it NOW I have no idea. But, we know some directions
more realistic
Minimizing the gap between state-of-the-art capture and modeling

7. Future work More details wrinkles and folds high quality
50k vertices maybe
more powerful
expression transitions
aging progression

8. Capture results, not Modeling
