Single-Patch NURBS Face

We describe a novel NURBS surface fitting method to a human face model. Our first step is to resample of the original mesh model. The next step we fit a tensor product NURBS surface to the grid points. Our method is characteristic in that we use only one patch to fit the model. By eliminating the need to make patch boundaries, our resampling and fitting method can be used for interactive system with minimum user interactions.
