Statistical 3D Face Modeling introduction to a literature review Chao Zhang CVPR Group, University of York cz679@york.ac.uk

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!)

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.

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

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

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

Capture results, not Modeling
