MyWaveletDenoise
- 对输入信号进行有效的去噪,使用小波分解后对噪声信号去除,并重构得到去噪信号(The input signal is effectively denoised, and the noise signal is removed by wavelet decomposition, and the denoised signal is reconstructed)
Gabor
- 二维gabor变换提取图像的空间多尺度多方向的特征(2 dimensional gabor transform)
小波变换
- 小波变换原理以及常用小波变换介绍,并且有多分辨率的分析(Wavelet and Multiresolution Analysis)
emd
- 经验模态分解程序包 希尔伯特黄变换程序的matlab程序仅供参考(Empirical mode decomposition package Hilbert Huang transform program)

MATLAB多方法去高斯白噪声-1
- matlab方法去除高斯白噪声,比较全面,有效。很好用的代码(Matlab method to remove gaussian white noise, more comprehensive, effective. Very handy code)
Autocorrelation
- 编写MATLAB程序,产生协方差函数为C(τ)=9??^(?10|??| )的零均值平稳高斯过程,产生一条样本函数.测量所产生样本的时间自相关函数,将结果与理论值比较。(Procedures for the preparation of MATLAB produced C covariance function (tau) =9^ (- 10||) zero mean stationary Gauss process to produce a sample function. Measuring
emd
- emd的方法对信号进行处理,得到imf分量(The EMD method processes the signal and obtains the IMF component)
整数小波变换
- 整数小波变换,可以直接运行,对图像小波分解(Integer wavelet transform)

- 可用于图像去噪,增强。语音为MATLAB,双树复小波变换的代码。(It can be used for image denoising and enhancement.Speech is MATLAB, dual tree complex wavelet transform code)
DWT_1D
- 本程序用Mallat算法实现小波变换,方法简答以实现(This program uses the mallat algorithe to implement wavelet transform)
decomposition
- 运行emd,得到输入信号X的固有模态函数(imf),每列代表着信号X的一阶分量,X就是我们采集的信号。 hhtdn是hht去噪的程序,可以不看,仅看emd 和 findpeaks wvtdn是wavelet去噪程序,如果只是分解信号,仅用下面的语句即可 [C,L] = wavedec(x_noise,dl,wn); x_noise就是我们采集的信号,dl是分解的阶数,wn是分解的母小波名称(% Empiricial Mode Decomposition (Hilbert-Huang
