A New Compatible Remeshing Approach for 3D Face Construction and Expression Clone

This paper presents a new compatible remeshing approach, by morphing with Radial Basis Function based on approximate geodesic distance (G-RBF) followed by a mesh optimization to generate compatible meshes efficiently while approximating the input target geometry accurately. To test the proposed approach, a prototype is implemented to clone expressions onto the personalized 3D face model. A PCA based reconstruction algorithm is employed firstly to reconstruct a personalized 3D face model. Then, a personalized cartoon model is obtained by morphing and blending of the existing cartoon model and the 3D face model using the proposed compatible remeshing algorithm. Finally, an efficient expression cloning algorithm based on compatible remeshing is presented to clone the existing facial animation onto the personalized cartoon model. The proposed technique is useful for a wide range of applications, such as computer games, animation films and online avatars.
