Sigmoid

用matlab对照片进行频域变换，并进行简要分析比较DCT、DFT、WH等方式重构的图像与原始图像之间的差别，并写出报告(use matlab to perform the frequence transform and use DCT/DFT/WH to rebuild the picture, analysis the difference and report)

BRC MATLAB code for BRC.fig BRC, by itself, creates a new BRC or raises the existing singleton*. H = BRC returns the handle to a new BRC or the handle to the existing singleton CALLBACK ,hObject,eventData,handles,...) calls the local function named CALLBACK in BRC.M with the given input arguments.BRC Property , Value ,...) creates a new BRC or raises the existing singleton.Starting from the left, property value pairs are applied to the GUI before BRC_OpeningFcn gets called.An unrecognized property name or invalid value makes property application stop. All inputs are passed to BRC_OpeningFcn via varargin.See GUI Options on GUIDE s Tools menu. Choose "GUI allows only one.instance to run (singleton)".Edit the above text to modify the response to help.Begin initialization code - DO NOT EDIT

This code is to generate FIR filter

说明：  分布式视频编码程序，不包括传统帧编码部分，仅WZ编码部分，对信源进行了分类，小波变换，LDPC等(Distributed video coding process, not including traditional frame coding part, only part of WZ coding, the source for the classification, wavelet transform, LDPC, etc.)

经验模态分解emd，HIlbert变换工具箱，用以处理非线性非平稳信号，时频分析。(Empirical mode decomposition emd Hilbert transform toolbox for nonlinear and non-stationary signals, time-frequency analysis.)

三自由度直齿轮动力学方程求解，希望对初学者有所帮助。( Dynamic equation of three-DOF gear, hope it is helpful for beginners.)

这是我们课程设计时所写的一个OFDM系统仿真程序，OFDM系统仿真.doc是我当时写的设计报告。(This is our curriculum design of a OFDM systems written of the OFDM systems simulation. When I was writing doc design reports.)

this is a one program about active contour

卡尔曼滤波程序，卡尔曼滤波在动目标跟踪时的应用，(kalman filtering, target tracking)

matlab 门限模型 这是一个比较好的用matlaB软件做门限模型的方法。(matlab threshold model which is a good software to do with matlaB threshold model.)
