自己写的卡尔曼滤波源程序，仿真对匀加速转弯目标的跟踪(Write their own source of Kalman filter, simulation of the absorption curve to accelerate target tracking)

PCA是一种掌握事物主要矛盾的统计分析方法，它可以从多元事物中解析出主要影响因素，揭示事物的本质，简化复杂的问题。本程序实现了基于PCA特征脸的人脸识别。(PCA is a major contradiction to grasp things, statistical analysis, it can parse out things from multiple main factors, revealing the essence of things, simplifying complex issues. This program implements the features of face recognition based on PCA.)
