Growing B-spline Model for Efficient Approximation of Complex Curves

Growing B-spline model of curve approximation exploits local control of B-spline which leads to efficient approximation of complex curves, even with higher order B-splines. Approximation is carried out progressively (growing) in this model which is another factor for efficient approximation. Control points are adjusted / re-positioned in each iteration of approximation based on error between two curves. Proposed method can avoid any need of parameterization and complex computations. Proposed growing model can be applied with any degree of B-spline curve.
