说明：  matlab高级讲义，可以使你快速提高matlab技能(matlab senior notes, you can rapidly improve your skills in matlab)

用matlab编写程序，生成ZC序列，画出自相关函数与循环自相关函数(Programming with MATLAB, generating ZC sequence, and drawing autocorrelation function and cyclic autocorrelation function.)

获取WAV声音文件，转换成数字的两个程序代码。(Get WAV sound files, converted into digital code for the two procedures.)

this file is for tracker ball from a image

说明：  测试网络的容错性,并且对实际含噪声的字母进行识别，以实现BP网络的识别功能。(Test network fault tolerance, and the actual identification of letters with noise, to achieve the BP network, recognition.)

Source Code for bag of features, developed in Matlab

DSP实现数字信号处理的无限长滤波器，东南大学第三次实验(DSP digital signal processing of the infinite filter, Southeast University, the third experiment)

用双谱和小波变换去除信号中加性高斯噪声的相关程序 1.实现单个变量的双谱分析程序 2.用傅立叶反变换求自相关函数的程序 3.用fft求取喜好频谱、功率谱、均方根谱、对数谱的程序 4.读取.wav语音信号后用小波去加信白噪声的程序 5.用各种小波和阀值对同一信号去加性噪声效果比较的程序 (Double-spectral and wavelet transform to remove the signal plus Gaussian noise procedures 1. To achieve a single variable pairs of spectral analysis procedures 2. Using Fourier inverse transform procedures for seeking self-correlation function 3. To strike a preference to use fft spectrum , power spectrum, RMS spectrum, several spectra of the procedure 4. read. wav audio signal with wavelet plus a letter to the white noise process 5. with a variety of wavelet and threshold on the same signal to additive noise Comparison program)

说明：  将小波变换应用于信号消噪,去除冗余分量后，提取信号主要特征(the wavelet can be applied to the signal denoise and feature extraction)
