Recently we introduced the concept of correspondence based face space [1,2,5]. The technique derives a general flexible face model, which allows to synthesize novel realistic 3D-models of human faces [7]. The flexible model is obtained in an automated learning procedure from the example faces of our 3D face database [6]. The procedure extracts the common structure of all faces, the prototype face, and codes individual faces through their deviation from this prototype. To develop this model, which is mainly based on the linear combination of examples, we had to solve the correspondence problem beteen the indiviual example faces. That is, we had to develop algorithms that are able to find all corresponding points on the surface of the example faces. |
