用dwt函数实现了一层小波变换，并将各分量用图像显示了出来(Dwt function implementation with a layer of wavelet transform, and image display using the component out)

说明：   此函数用于研究Mallet算法及滤波器设计 此函数用于消噪处理 分解的高频系数采用db9较好,即它的消失矩较大 分解的有用信号小波高频系数基本趋于零 对于噪声信号高频分解系数很大，便于阈值消噪处理(this function for research Mallet filter algorithm design and function for Denoising decomposition of high-frequency coefficients Terminal better that it's vanishing moments larger decomposition of useful signal, high-frequency coefficients tends to zero for high-frequency signal noise decomposition coefficient great ease threshold Denoising)

bpsk 数字调制 本程序包括基本编程和仿真，希望对大家有帮助(This procedure bpsk digital modulation including basic programming and simulation, we hope to help)

说明：  此段代码的功能是对宽带阵列信号的输出结果进行仿真(This is the source code of simulation for the array output when wideband signals are received.)

基于第三代通讯wimax核心编码ofdm编码的matlab性能仿真(based on the third generation telecommunications wimax core coding ofdm coding Matlab Performance Simulation)

这是我另一个同学的关于图像处理与机器学习的作业，对四组图像提取特征值，进行分类识别。LIBSVM.文件里包含代码，及一些参数调试。(This is another of my classmates on image processing and machine learning operations on four sets of image feature extraction values ​ ​ for classification. LIBSVM. File contains the code, and some parameters debugging.)

在matlab环境下，对自定义目标的修改，讲解tlc文件，main文件的含义。(In the matlab environment, modify the custom targets, explain tlc files, main file meaning.)

说明：  人脸肤色检测，在转换成Ycbcr格式后用相关系数进行肤色似然度计算，检测属于肤色的像素。(Skin color detection, the conversion into Ycbcr format color by correlation coefficients calculated likelihood, detection is skin color pixels.)
