Degree Reduction of B-Spline Curves Using Perturbations Constraint and Least Squares Approximation
The technique of perturbations constraint when applied to degree reduction of Bézier curves gives fairly well results.This paper discusses why these kind of technique have limitation when applied to B-spline curves,and the least squares approximation approach is presented for reducing the degree of B-spline curves.Examples comparing the new method with existing ones are illustrated.
