本文件用matlab 语言，对kalman滤波的方法进行仿真，画出来原始曲线，观察值，和跟踪曲线，会对初学者有很大的帮助！(this document using Matlab language, Kalman filtering method simulation, sketching out the original curve, observed values, and tracking curve, beginners will be of great help!)

大牛人的图象恢复代码．全变分离散化的方法．经典中的经典．(Daniudi people to restore the image code. BCH-wide variable separation method. Classic classic.)

使用基于PCA+KNN算法实现的人脸识别，本算法的优点在于使用的是基于2DPCA的方法，计算时间更短，效率更高。(PCA+ KNN-based face recognition algorithm, the advantage of this algorithm is based on the use of 2DPCA method in calculating the time is even shorter, more efficient.)

说明：  pca-svm的人脸识别，利用pca进行人脸特征提取，再利用svm进行聚类分析(Face recognition based on PCA SVM)
