matlab图像处理的一些命令，还有使用的例子，对图像处理初学者应该会有帮助的(matlab image processing commands, there are examples of the use of image processing should be helpful for beginners)

Edge Detection,Color Find,Maximum Color in Image User Interface

1、 从网上下载人脸图像，构建人脸训练数据库和测试数据库，采用K-L变换进行特征脸提取，并实现人脸识别。通过K-L变换在人脸识别中的应用，加深对所学内容的理解和感性认识。(1, face image downloaded from the Internet, the construction of the training and test database face database, using K-L transform features face extraction, and realize the face recognition. Through k-l transform in face recognition application, deepen the understanding of the content of study and perceptual knowledge.)

有均匀线阵的CRB曲线，线性调频脉冲压缩的Matlab程序,小波包分析提取振动信号中的特征频率。( There ULA CRB curve, LFM pulse compression of the Matlab program, Wavelet packet analysis to extract vibration signal characteristic frequency.)

Earthquake Engineering and Structural Dynamics(You can input any number of stores by giving the mass, stiffness and damping values. Input the gamma and beta values which are related to Newmark Integration Mtd. Press Newmarks Integration button to input the values. Input the any number of storey that you expected to see the deflection for particular Earthquake. Press “Storey No” button to get that number. If you like only, you will input the period and press “Period” button. Finally press calculate button to see final results. Also you can see the both graphs in log scales also.(Please right click on the graph as shown above). You may see what type of analysis method is used. (Average acceleration relation ship or Linear variation of acceleration).)

用于图像配准等应用的互信息计算，为Matlab程序，比较简单，但很实用。(for image registration applications such as the mutual information, as Matlab procedures are relatively simple, but practical.)

跳频图案是跳频通信成功的基础，本代码计算了r=15时的m序列优选对，通过找到m序列的特征相位，模2得到了平衡Gold序列(Frequency hopping patterns is fundamental to the success of frequency-hopping communication, the code calculated the r = 15 when m sequence optimization right, by finding the characteristics of m sequence phase, mode 2 has been balanced Gold sequences)

一个提取遥感影像光谱特征的程序，易于理解，分类精度高(An extraction of remote sensing image spectral characteristics of the program, easy to understand, high classification accuracy)

通过差值方法填补matlab变量中的NAN值，针对二维以内的变量，变量中不能有整行或整列的NAN值(Fill NAN value in matlab variables by the difference method, for less than two-dimensional variables, variables can not have an entire row or column values ​ ​ of NAN)

当前的很多海洋数据都是海量数据，传统的ftp下载费时费磁盘，因此，openDAP方式越来越多，通过opendap可以选择直接需要的时间、空间范围内的资料。nctoolbox结合matlab实用，效果非常好的opendap工具包(NCTOOLBOX- 20130305 Full instructions and documentation at: http://code.google.com/p/nctoolbox/ We are in the progress of moving the project hosting here to github.com. Brief summary: *Prequisites *Matlab R2008a+. You can verify the version of Matlab by typing: version *Java 6+. You can verify the version of Java used by Matlab by typing: version( -java ). *The version returned should start with Java 1.6 . If it starts with Java 1.5 you can try updating the Matlab JVM: http://www.mathworks.com/support/solutions/en/data/1-1812J/ or use the older nctoolbox-20091112 version of this toolbox. )
