Chapter 4 Face Modeling We first introduce an overview of our modeling method [173], and describe the generic face model and facial measurements. Then we present an approach for adapting the generic model to the facial measurements. Finally, an adapted 3D face model of an individual is texture-mapped and reproduced at different viewpoints for visualization and recognition. 4.1 Modeling Method For efficiency, we construct a 3D model of a human face from a priori knowledge (a generic face model) of the geometry of the human face. The generic face model is a triangular mesh, whose vertices can precisely specify facial features that are crucial for recognition, such as eyebrows, eyes, nose, mouth, and face boundary. We call these features recognition-oriented features. The locations and associated properties of these recognition-oriented features are extracted from color texture and range data (or 97
