国外分享的采用特征点匹配的指纹识别例子

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.)

将扩展卡尔曼滤波用于非约束型非线性优化问题，代码具有极高的参考价值。(A function using the extended Kalman filter to perform unconstrained nonlinear optimization)

在MATLB中的OFDM的无线传输信道仿真。(Wiley10_MIMO-OFDM Wireless Communications with MATLAB )

Analogous considerations can be made for what concerns the other kind of MMI used in this project: the 1x2. Its single input waveguide is designed straight, while both output waveguides are curved as usual (with a radius of 500  m). Since the toleration curves are very similar to the precedent case, only the length and offset simulations are shown:

说明：  直接矢量转子磁场定向控制的MATLAB仿真，虽然闭环存在一些问题，但基本可以解释矢量控制。(Direct rotor field oriented vector control MATLAB simulation, although the closed-loop, there are some problems, but the basic vector control can be interpreted.)

matlab练习程序（7个二维不变矩） 《数字图像处理》书上说这7个矩是旋转、缩放、平移不变的，因此用这7个矩就可以代表一个图像了。我只试验了缩放的，这几个数几乎是不变的，也许做图像检索的时候可以用到。代码：
