  • Patent number: 7519828
    Abstract: A personal identity verification process and system adopts an error correcting output code (ECOC) classifier approach. Image data representing an input facial images is processed to generate a first (ECOC) classifier output vector and image data representing a class of different training images of the face of an individual are processed to generate a set of second ECOC classifier output vectors. Authenticity of the input facial image against the class of training images is evaluated by measuring distance between the first ECOC classifier output vector and the set of second ECOC classifier output vectors using a first order Minkowski metric.

  • Patent number: 7436985
    Abstract: A personal identity authentication process and system use a class specific linear discriminant transformation to test authenticity of a probe face image. A ‘client acceptance’ approach, an ‘imposter rejection’ approach and a ‘fused’ approach are described.

  • Publication number: 20070196000
    Abstract: A novel approach to 2D face authentication that is assisted by client specific 3D models is proposed. Each 3D model is acquired during the client enrolment together with the usual client template. Any 3D face model acquisition system may be used for the purpose. The future authentication of client's identity by the face biometric system is based on 2D probe only, with the stored 3D model and the client template used for reference. In a verification scenario, the authentication process is assisted by the 3D model associated to the claimed identity.
