图像的5/3小波变换的matlab代码。程序简短，易懂。(Image 5/3 wavelet transform matlab code. Program brief and easy to understand.)

本程序应用小波变换进行电力系统的在线监测。电力系统在线监测中的检测信号含有大量的背景噪声，不便于检测。应用小波变换解决这一问题。程序中应用db3小波对信号进行5层分解，并得出了各层的细节信号与逼近信号。(This procedure based on wavelet transform power-line monitoring system. Online monitoring of power system test signal contains a lot of background noise, not easy to detect. Application of wavelet transform to resolve this problem. Application procedures for db3 wavelet signal decomposition layer 5, and arrive at different levels of detail signal and approximation signal.)

利用小波包变换对信号进行分解及重构，对于初学者是一个很好的学习材料。(Wavelet packet transform signal decomposition and reconstruction, is a good learning materials for beginners.)

实现信号希尔伯特变换，以及小波变换，小波变换要求数据长度是2的N次幂(The signal Hilbert transform and wavelet transform, wavelet transform requires that the data length 2 is N th)

说明：  用Java实现97提升小波变换，动态演示和可视化(Realizes 97 promotion wavelet transformation with Java, dynamic demonstration and visualization )

小波变换与分数傅里叶变换理论与应用(冉启文）电子版，介绍了小波变换、多分辨分析、小波构造、时频分析、小波包、塔式算法、分数傅立叶变换等内容，是一本不错的教材。(Wavelet Transform and Fractional Fourier Transform Theory and Applications (Ran text) electronic version, introduced the wavelet transform, multiresolution analysis, wavelet construction, time-frequency analysis, wavelet packet, tower algorithm, the fractional Fourier transform, etc., is one The good teaching materials.)

MATLAB实现的高斯平滑滤波源代码，用了高斯函数的定义来做，附实例，效果很好(gauss filter by matlab)
