摘要 该文给出了一类具有双对称4-进双正交小波的构造方法,该小波类可以由它的低通滤波器确定,因此,其自由度可以运用到应用背景.构造具有较高消失矩的双对称双正交多小波族,为相关应用提供了大量选择. A class of four-bank bisymmetric biorthogonal wavelet bases has been constructed, in which any wavelet system can be determined by its low-pass filter. Thus, the least restrictive conditions are needed for forming a wavelet so that the free degrees can be reversed for application requirement. Some concrete examples with high vanishing moments are also given. These wavelets can process the boundary conveniently, and enjoy the highly efficient computations in application.
