Abstract
This paper presents an efficient method to solve the approximation problem of the rational Bezier curve by continuous piecewise polynomial curve in $$ L_{2} $$ -norm. For this purpose, extended Jacobi wavelets together with the Gauss–Jacobi quadrature rules are employed. The proposed technique has some advantages such as: simplicity, high accuracy and fast computation. Also, the method in the paper performs multi-degree reduction at one time and does not need the stepwise computing. Several examples are given to illustrate the effectiveness of the algorithm.
