| 摘 要： | 将线性分形插值推广到B-样条上,可避免线性分形插值局限性,进一步扩大分形理论的应用范围。分形插值应用的关键问题,是如何合理地确定垂直尺度因子di的值,而它的计算却没有一种很有效的方法。通过解析方法,获得了均匀B-样条分形插值“S”点的代数解,从而,可准确计算出垂直尺度因子,解决了影响B-样条分形插值应用的难题。

| Abstract: | Linear fractal interpolation has been applied in many fields.It can make the linear fractal interpolation applied extensively that put the B-spline in the linear fractal.The key of the linear fractal interpolation is to define the contraction operators dirationally,and we have not any effective method to define the contraction operators now.Through this paper the analytic solution of even B-spline fractal interpolation and the contraction operators can be got accurately. |

| Keywords: | B-spline fractal interpolation contraction operators |
