摘要
利用提升格式 ,构造了 CDF型 [1]的双正交小波 ,并探讨了提升算子 S的选择规律 ,最后给出构造实例 .结果表明 :这种构造方法比传统的构造方法简单、易行 ,而且选择不同的提升算子S,可以得到不同性质的双正交小波 。
The CDF biorthogonal waveletes are constructed by lifting scheme. At the same time, the regulation of lifting operator S is got. Finally, some examples are given. The results show: this method is much easier than the traditional methods. Moreover, more biorthogonal wavelets can be gotten based on different operators. So, the construction of method is more useful than other methods.
