| 摘 要： | 提升格式作为一种新的小波分解计算过程使得运算量大大减少,但缺陷是不能有效构造小波.通过分解对称正交小波成为提升格式得到一新型提升格式,克服了已有提升格式的缺陷,并通过实例说明了算法的有效性.

| Abstract: | As a new computational process,the known lifting scheme is used to decrease the complexity,but it cannot be used to construct wavelets efficiently.In this paper,we presented a new kind of lifting scheme,which was obtained by fractionating symmetric orthogonal wavelets into lifting steps.Therefore,the weakness mentioned above is overcome,and some examples are given to illustrate it. |
