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