摘要:
我们提出了一种高效的方法来解决用贝塞尔曲线逼近有理贝塞尔曲线的约束最小二乘逼近问题。所提出的算法利用双约束伯恩斯坦基多项式,这些多项式与雅可比标量积相关,并利用其递推性质。给出了实例,展示了该算法的有效性。
英文摘要:
We present an efficient method to solve the problem of the constrained least squares approximation of the rational Bézier curve by the Bézier curve. The presented algorithm uses the dual constrained Bernstein basis polynomials, associated with the Jacobi scalar product, and exploits their recursive properties. Examples are given, showing the effectiveness of the algorithm.
