  • Efficient classification of three dimensional face models for human identification and other applications
    Publication number: 20050226509
    Abstract: Three dimensional face recognition via vectorizing samples that are in an enrollment data base. The vectors are formed by comparing faces in the enrollment database with reference faces, and determining differences between the actual faces and the reference faces. Those differences are then formed into an N dimensional vector representing the classified faces. A query face is then similarly vectorized and compared to precomputed vectors indicative of the faces in the database. Another technique is described for updating the reference faces based on an error level.

  • Passive stereo sensing for 3D facial shape biometrics
    Publication number: 20050111705
    Abstract: A face recognition device which operates in sunlit conditions such as in sunlight, or in indirect sunlight. The device operates without projection of light or other illumination to the face. Stereo information indicative of the face shape is obtained, and used to construct a 3D model. That model is compared to other models of known faces, and used to verify identity based on the comparison.
