字母图像识别算法，O, E, A, U 四个字母进行识别，该算法加入一定噪声之后依然有效。(The basic goal of the program is to perform letter recognition of vowels O, E, A, U in paragraphs provided in form of black-and-white images. Using the training paragraph image, we are allowed to train our program to distinguish among letters. Some difficulties that need to be resolved are noise, joined letters, scaled or tilted letters, and distinguishing between letters that are similar to each other. )

说明：  采用matlab产生信号波形，实现QPSK编码。(Waveforms generated by matlab to achieve QPSK encoding.)

　计算机人脸识别技术( Face Reocgnition)就利用计算机分析人脸图像,从中提取出有效的识别信息,用来辨认身份的一门技术。[ 1 ]即对已知人脸进行标准化处理后,通过某种方法和数据库中的人脸样本进行匹配,寻找库中对应人脸及该人脸相关信息。人脸自动识别系统有两个主要技术环节,一是人脸定位,即从输入图像中找到人脸存在的位置,将人脸从背景中分割出来,二是对标准化后的人脸图像进行特征提取和识别。本文中介绍的PCA (特征脸)方法就是一种常用的人脸 特征提取方法。(Computer Face Recognition Technology (Face Reocgnition) on the use of computer analysis of facial image, to extract the valid identification information used to identify the status of a technology. [1] that is known to standardize treatment of face, through a method and a database of face samples for matching, search library, the corresponding face and the face-related information. Automatic face recognition system has two main technical aspects, first, face location, that is, from the input image to find the location of the face there, the faces will be split out from the background, the second is, the standard features of face images extraction and recognition. Described in this paper PCA (Eigenfaces) method is a common facial feature extraction method.)

matlab程序，有关分岔图，主要是ode45(matlab procedures, the bifurcation diagram, mainly ode45)

说明：  conjugate gradient for solving system of equations

this is a database for jus withe 218 samples and 700 features
