摘要:
该文由框架定义导出其自扩展性,并在此理论基础上把调制思想运用于小波变换,提出了一种基于非正交实小波的框架扩展方法,并以墨西哥草帽小波为例对该方法给予详细的说明。使用该方法可以构造出具有正交小波尺度函数特性的框架———调制小波,这种调制小波不但具有优良的滤波特性,而且对噪声具有鲁棒性,还兼有窗函数易于实现的优点。
Abstract:
Self- spanning property of the Frame is deduced from it s definition. Based on this theory, the modulat ing method is int roduced in w avelet transform and therefore a method on how to span a frame f rom Non-orthogonal RealWavelet is presented. It s spanning method is il- lust rated in details by Mex ico Hat Wavelet. T he frames spanned by this method ( named modulated w avelet) share many propert ies of scaling funct ion of orthogonal w avelets and possess excellent filtering property, robustness to noises ad easily realizing property of w indow functions.
