The research of adapting non-control points based on neutral facial model

The model modulation is an important step in the virtual facial composition. This paper is focused on how to change a neutral facial grid model into a given facial model, which means the position of the grid points and the control points are already given in the 3-D neutral facial grid model, while the position of the control points are changing, how should we change the position of the non-control points in order to approach the given facial model. So we came up with a way to modulate the non-control points based on the RBF interpolation model in this paper and the inverse quadratic polynomial is used in RBF. Because RBF has very good overall continuity and we can also make sure the locality of the interpolation by modulating the attenuation parameter, so we are able to have a very good result of model modulating. This paper has analyzed the time complexity of this algorithm and we have also talked about the locality of this algorithm.
