Abstract |
This paper presents new techniques for generating varied realistic geometric models of human faces by synthesizing local facial features according to anthropometric control parameters, and for generating a full-head texture from a face image of the scanned data for realistic rendering. We automatically register 3D face scans in a large database by deforming a generic head mesh to fit each scanned face shape. Once we have a common surface representation for each face scan, we form local feature shape spaces by applying principal component analysis to the data sets of facial feature shapes. We parameterize the example models using face anthropometric measurements and predefine the interpolation functions for the parameterized examples based on radial basis functions. At runtime, the new face geometry is generated at an interactive rate by evaluating the interpolation functions with the input anthropometric parameter values. We automatically generate a full-head texture from parameterized texture of the face region. In particular, we address the creation of individual textures for ears. Apart from the initial adjustment of feature point positions, our method is fully automated. |
