利用Kalman滤波器跟踪一个旋转的点，是用Opencv编的-Use of Kalman filter to track a rotating point

openCV中的代码 有2ROI Hough检测直线 kalman跟踪小球 播放视频 车道线检测工程代码 -openCV code 2ROI Hough kalman and other thing

卡尔曼滤波(Kalman filtering)一种利用线性系统状态方程，通过系统输入输出观测数据，对系统状态进行最优估计的算法。本程序使用opencv进行卡尔曼滤波。-Kalman filter (Kalman filtering) A linear system equation of state, observation data input and output through the system, the system state optimal estimation algorith
