摘要 研究了二元小波紧框架的结构,这个小波紧框架是由V1中的n个函数构成.首先给出由这n个函数生成二元小波紧框架的充分条件,并借助尺度函数给出了构造二元小波紧框架的显式公式,其次给出二元小波紧框架的分解与重构算法,并构造了小波紧框架的数值算例. The construction of bivariate wavelet tight frames is studied. The wavelet tight frames consist of n functions of V1 space. First, the sufficient conditions for existence of bivariate wavelet tight frames generated by the n functions are presented, and explicit constructing formula of bivariate wavelet tight frames is given. Then,the decomposition and reconstruction formulas of bivariate wavelet tight frames are derived. Finally, the examples of bivariate wavelet tight frames are given.
