说明：  这个是利用图像分解和Logistics混沌序列可以对图像先进行加密然后进行隐藏在另一个图像中再进行解密(This is the use of image decomposition and Logistics chaotic sequence can be encrypted on the image first and then proceed to hide in another image and then decrypt)

此代码是利用 MATLAB 工具设计的一个指纹数字图像识别系统的关键代码(fingerprint identification)

这是一个用MATLAB做的基于矩特征的图像特征提取，值得借鉴-This is a done using MATLAB moment characteristics based on image feature extraction, is worth learning from(This is a MATLAB moment in image-based feature extraction, worth learn-this is a done using MATLAB moment characteristics based on image Feature Extraction, is worth learning from)

MFIE.m 本程序用于磁场积分方程求解圆柱散射

对一个图像进行锐化。让图像看上去更清晰，轮廓更明显。(An image sharpening. Let the image looks clearer and more obvious profile.)

人脸识别 2DMSD 二维最大散度差判别分析 (face recognition 2_dimension scatter difference )

二叉树定价模型是期权定价模型中最为简单也是最为实用的定价模型，其极限就是Black sholes定价模型的结果。(Binary tree pricing model is the most simple option pricing model is the most practical pricing model, the limit is Black sholes pricing model results.)

说明：  code for image subtraction

滑动窗算法，可用于实现动态排序，可应用于航班排序(Sliding window algorithm can be used to achieve dynamic sequencing and can be applied to flight scheduling.)
