  <abstract>"The Human Face Project" is a short film documenting an effort at Walt Disney Feature Animation to track and animate human facial performance, which was shown in the SIGGRAPH 2002 Electronic Theater. This presentation will outline the techniques developed in this project, and demonstrated in that film. The face tracking system we developed is an example of model-based computer vision, and exploits the detailed degrees of freedom of a geometric face model to confine the space of solutions. Optical flow and/or successive rerendering of the model are employed in an optimization loop to converge on model parameter estimates. The structure of the model permits very principled mapping of estimated expressions to different targets.  Of critical importance for media applications is the handling of details beyond the resolution or degrees of freedom of the tracking model. We describe behavioral modeling expedients for realizing these details in a plausible way.
