3d Face Correspondence Based on Uniform Mesh Resampling Combined with Mesh Simplification

This present study, proposes a new 3D face correspondence method. A uniform mesh re-sampling algorithm is combined with mesh simplification algorithm to make correspondence between vertices of prototypical 3D faces. Uniform mesh re-sampling algorithm is developed to obtain the same topology between 3D faces with different structures. A global error metrics is proposed and mesh simplification is implemented on 3D faces with same topologies simultaneously. The new method overcomes the limitation of conventional uniform mesh re-sampling and optical flow algorithm, decreases the vertices, and triangles that need to represent 3D face while preserving correspondence between vertices of the prototypes. The experimental results show the new method gives good performance on computing 3D face correspondence.
