3-D Face Reconstruction Using RBF and B Spline Method

3-D specific face model construction by way of 2-D face image is an active topic in 3-D face modeling research. In this paper, stereoscopic sense of vision is used to reconstruct 3-D feature points. Then multi-layer and multi-region RBF (radial basis function) based on feature points of frontal and profile face image is adopted for reconstructing the generic face model to get 3-D specific face model with visible organ characters. Moreover, B spline is used in 3-D face curve reconstruction. Then the near face global texture is mapped onto the reconstructed specific face model and the 3-D realistic specific human face model is obtained. Experiments show that the method is easy for constructing near face global texture, in which the reconstructed specific face model is natural and realistic, and can be used for realistic specific face modeling in facial animation.
