<strong>Face</strong> <strong>Modeling</strong><br />
We first introduce an overview of our modeling method [173], <strong>and</strong> describe the generic<br />
face model <strong>and</strong> facial measurements. Then we present an approach <strong>for</strong> adapting the<br />
generic model to the facial measurements. Finally, an adapted 3D face model of an<br />
individual is texture-mapped <strong>and</strong> reproduced at different viewpoints <strong>for</strong> visualization<br />
<strong>and</strong> recognition.<br />
4.1 <strong>Modeling</strong> Method<br />
For efficiency, we construct a 3D model of a human face from a priori knowledge (a<br />
generic face model) of the geometry of the human face. The generic face model is a<br />
triangular mesh, whose vertices can precisely specify facial features that are crucial <strong>for</strong><br />
recognition, such as eyebrows, eyes, nose, mouth, <strong>and</strong> face boundary. We call these<br />
features recognition-oriented features.<br />
The locations <strong>and</strong> associated properties of<br />
these recognition-oriented features are extracted from color texture <strong>and</strong> range data (or<br />
