    离散小波变换是指在特定子集上采取缩放和平移的小波变换,是一种兼具时域和频域多分辨率能力的信号分析工具。此变换运用可以缩放平移的小波代替固定的窗进行计算分析,主要应用于信号编码和数据压缩。(Discrete wavelet transform refers to the specific subset take scaling and translation on the wavelet transform, is a kind of multi-resolution ability both time domain and frequency domain signal analysis tool. This transformation can use zoom translational wavelet calculation and analysis instead of the fixed window, mainly used in signal coding and data compression. )

    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.)
