Efficient Spline Interpolation Curve Modeling

We present an approach to model handwriting like curves with the cubic spline interpolation function. Different from NURBS such as Bezier and B-spline curve modeling, the huge complexity of the traditional spline interpolation have been obstructed and limited the application of spline curve modeling. We propose an efficient local cubic spline interpolation curve modeling algorithm and provide an approach to apply the algorithm to model arbitrary shape built from free form curves.
