基于OpenCV的Kalman滤波算法。利用Kalman滤波算法实现目标跟踪，本例中具体跟踪对象为随机产生的圆的轨迹，预测轨迹中下一点的位置，标记出来并给出相应的运动轨迹。-The Kalman filtering algorithm based on OpenCV. The use of Kalman filter algorithm for target tracking, in this case specifically track the object is randomly generated circle track, forecast track of the location of the next point, mark out and give the corresponding trajectory.
