On a Modified Durrmeyer-Bernstein Operator and Applications

Abstract

We present two applications of a modified Durrmeyer-Bernsteinoperator introduced by Goodman and Sharma. A new method isproposed achieving a “good” degree reduction of a Beziercurve with endpoint interpolation. A convenient algorithm will begiven providing an easy and practical method for computing thedegree reduced curve. Then, given a set of (r+1) points, weconstruct a degree n Bezier curve approximation within adistance O(n −1/2 ) from the given points, where n does notdepend on r.
