mit的信号处理考试试卷，非常棒！可以理解老美的学习思路。(mit signal processing exam papers, great! Americans can understand the idea of learning.)

Hill Chiper Encrypt using matlab

Matlab不用说就知道是什么了, 在图像处理中Matlab也很强大, 奉上一个教程.(Matlab do not know what it says in the Matlab image processing is also very strong, just give a tutorial.)

算法是基于均匀线阵的DOA方法，包括MUSIC算法和ESPRIT算法！(MUSIC DOA and ESPRIT DOA based on ULA)

经典LSB算法，对于研究水印算法人们很有启发，希望一同进步，谢谢。(Classic LSB algorithm, it is useful for studying the watermarking algorithm inspired by the hope that with progress, thank you.)

遗传算法，一种启发式算法，用于演化求最优值(Genetic algorithm, a heuristic algorithm for evolutionary optimization)

自动提取目标图像轮廓边缘，同时分辨其颜色。(Automatic edge contour extraction target image, at the same time to tell its color.)

这是我自己编写的主元分析的MATLAB程序，主要包含经典多变量统计方法，运行结果不错，欢迎下载~(This is my own writing of the principal component analysis of the MATLAB program, mainly include classical multivariate statistical method, operation result is good, welcome to download ~)

系统采用的是直接标定摄像机内部参数的算法，算法借助于标定参照物直接计算摄像机的内参数。整个系统是在VC++环境下设 计并实现的，并借助了IPL和OpenCV的帮助，只要输入标定物的图像，系统就可以迅速而又准确地输出摄像机内参数的结果。通过3D 重构实验证明了该系统的有效性。相对于MATLAB实现方式，该系统使用更加方便、快捷。 (System are directly used in the internal parameters of the camera calibration algorithm, calibration algorithm by means of direct calculation of reference within the parameters of the camera. The entire system is in VC++ environment to design and implementation, and with the help of IPL and OpenCV, as long as the input image calibration objects, the system can be output quickly and accurately the results of camera intrinsic parameters. Through the 3D reconstruction of the experiment proved the effectiveness of the system. MATLAB implementation vis-à-vis the way the system more convenient to use, fast.)
