说明: 小波(Wavelet)这一术语,顾名思义,“小波”就是小的波形。所谓“小”是指它具有衰减性;而称之为“波”则是指它的波动性,其振幅正负相间的震荡形式。与Fourier变换相比,小波变换是时间(空间)频率的局部化分析,它通过伸缩平移运算对信号(函数)逐步进行多尺度细化,最终达到高频处时间细分,低频处频率细分,能自动适应时频信号分析的要求,从而可聚焦到信号的任意细节,解决了Fourier变换的困难问题,成为继Fourier变换以来在科学方法上的重大突破。有人把小波变换称为“数学显微镜”。
这套讲义生动详实的快速带领初学者掌握小波的基本要点,是不可多得的好材料!(This is a handbook about Wavelet.)
