摘要
介绍了母小波和完全小波系的概念,详述了它们的数字特征。给出了连续小波变换、离散小波变换和二进离散小波变换的定义并参考R2空问的矢量表达式导出了它们的逆变换。
The conceptions of mother wavelet and complete wavelet system are introtuced.Their digital features are described in detail.The definitions of con ti n nons, discrete, and dyadic discrete wavelet transforms are given,and their inverse transforms are deduced with reference to thevector expressions in R2 space.
