Abstract

We use RBF deformation and normal projection to regulate the scanned facial model, which makes their topology equivalent to a regular grid mesh and can generate principle components. Then the synthesized individual face model can be directly flatten to a regular plan, so the motion vectors of vertexes can be interpolated with barycentric coordinate. The regulation and animation remapping needs less than 40 key points and can work in real-time
