A system and method that includes a virtual human face generation technique which
synthesizes images of a human face at a variety of poses. This is preferably accomplished
using just a frontal and profile image of a specific subject. An automatic deformation
technique is used to align the features of a generic 3-D graphic face model with
the corresponding features of these pre-provided images of the subject. Specifically,
a generic frontal face model is aligned with the frontal image and a generic profile
face model is aligned with the profile image. The deformation procedure results
in a single 3-D face model of the specific human face. It precisely reflects the
geometric features of the specific subject. After that, subdivision spline surface
construction and multi-direction texture mapping techniques are used to smooth
the model and endow photometric detail to the specific 3-D geometric face model.
This smoothed and texturized specific 3-D face model is then used to generate 2-D
images of the subject at a variety of face poses. These synthesized face images
can be used to build a set of training images that may be used to train a recognition classifier.
