摘要
本文从非诱导的二维正交滤波的一类零点出发,构造紧集K,利用Cohen准则,得到非诱导滤波对应的(A,h)尺度函数正交的一个充分条件,并构造二维正交滤波的例子说明其应用.
In this paper we prove a sufficient condition for (A ,h)-scaling functions with bidimensional noninduced filters. We start from a special zero-sets of the filters and construct the compact set K , and obtain the proof by using Cohen criterion. Several examples are provided to illustrate the general theory.
