本例是一个简单的运动目标跟踪程序，对一个小球进行了实时的跟踪-This example is a simple object tracking program, for a small real-time tracking of ball

用MATLAB实现卡尔曼滤波，达到对动目标的实时跟踪，程序调试无误，完美运行。-Kalman filter using MATLAB to achieve real-time tracking for moving target, program debugging and correct, perfect run.

应用Kalrnan滤波原理，对运动目标进行跟踪，缩小目标的搜索范围，实现快速实时跟踪，使跟踪更为准确。理论分析和实验结果表明，该算法与常规的模板匹配法、直方图模板匹配法等算法相比，有效地提高了目标跟踪的速度及跟踪的准确性。(The Kalrnan filtering principle is used to track the moving target, reduce the search range of the target, realize fast and real-time trac
