摘要
在研究多分辨率分析和均匀B样条小波的基础上,给出均匀B样条曲线的小波表示。为达到在闭区间进行小波分解的目的,采用对称延拓有限个数据点的方法,实现了基于滤波器形式的均匀B样条小波分解和重构的快速算法。
Based on researching muhiresolution and uniform B-spline wavelet, the wavelet presentation of uniform B-spline curve are given. In order to decompose with wavelet on a bounded interval, a method of expanding f＇mite data points symmetrically is adopted. According to filter model, the fast algorithms of decomposition and reconstruction with uniform wavelet are realized.
