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)
1
- 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
DWTEA
- 提取小波系数包络特征，首先采用离散小波变换，提取小波系数后选取运动想象脑电相关子带，再用希尔伯特变换提取包络特征(Feature extraction of wavelet coefficients)
waveguideAndpoisson
- 1.利用matlab语言编写泊松方程，注意其中的边界条件要根据自己的实际情况确定，不一定都是那个值。 2.利用matlab语言编写横电波（TE）、横磁波（TM）的传播情况(1.Using MATLAB to write Poisson equation. Note that the boundary conditions should be determined according to their own actual conditions, not necessarily that val
Color_DWT_SVD_watermarking
- dwt-svd watermarking
345
