An-Improved-Heuristic-ACO

基于粗糙集的特征选择Matlab源程序。(Feature selection based on rough set.)

使用MATLAB打开TXT文件，并且用文件里面的数据画图(Open the TXT file using MATLAB, and use the data inside the drawing file)

说明：  通过导入后缀为.wav的噪声音频信号通过matlab进行频谱分析(Frequency spectrum analysis by importing noise audio signal suffixed with. wav through MATLAB)

这是一个完整版，包含调用文件。整个视频可以用在不同尺度和位置计算得来的特征集进行表示。Hog3D描述子由Alexander Klaser Marcin Marszał ek Cordelia Schmid等人提出的，将HOG的概念扩展，由静态图像特征提取扩展到视频序列的特征提取，在视频序列中的行人检测取得了较好的成果。(This is a complete version, including calls to the file. The video can be used in different scale and location characteristics were calculated set of representation. The Hog3D descriptor proposed by Alexander Klaser Marcin Marsza EK Cordelia Schmid et al, will the concept of HOG is extended static image feature extraction, extended to extract features of video sequences, pedestrian detection in video sequence and achieved good results.)

用模最大值法提取小波脊，该例中又两条小波脊，所以是多脊提取。同时又施加惩罚函数，控制lamda的值，可以得到较为平滑的小波脊。( using maximum modulus extract wavelet ridge, the case has two wavelet ridge, it is a multi-ridge extraction. At the same time to impose the penalty function to control the value of lamda,the extracted ridge can be relatively smooth .)

Reading a PGM image file

MATALAB功能强大且编程方便，广泛应用于各种算法的性能评估。文章简要 介绍了LSF声道滤波器原理，给出了用MATLAB实现LSF滤波器的流程图和程序代码。(MATALAB powerful programming convenience, which are widely used algorithms performance evaluation. The article briefed the LSF channel filter principle, given MATLAB LSF filter the flow chart and code.)

DCT COMPRESSION USING MATLAB

《通信系统仿真原理与无线应用》系统地介绍通信系统的设计、分析和仿真方法，还提供了大量极具参考价值的仿真实例。《通信系统仿真原理与无线应用》的全部仿真程序都是采用MATLAB编写的。这不仅方便读者理解仿真的实现过程，还允许读者修改或使用这些代码段来进行自己的仿真开发。章后提供了大量的参考文献和经过精心设计的各类练习题，方便教学。 此为英文原版书籍(Principles of Communication Systems Simulation with Wireless Applications is a hands-on, example-rich guide to simulating wireless communications systems. The first book to present complete MATLAB simulation models for predicting the impact of design changes, it treats every aspect of simulation: sampling, signal and system representations, filters, noise, Monte Carlo simulation, postprocessing, nonlinear and time-varying systems, waveform and discrete channels, co-channel interference, and more. It includes four detailed case studies.)

锁相环PLL原理与应用入门教程，很经典，值得一看(Principle and Application of phase-locked loop PLL Tutorial, very classic, worth a visit)
