本代码成功而及其有效地探测了运动物体的tracking的问题，对于人体的运动进行跟踪，经测试完好使用。-The successful and effective code to detect the problem of tracking moving objects, tracking the movement of the human body, tested good use.

该程序可以通过训练集对所构建的BP神经网络进行训练，并能通过测试集，即对不同的运动状态进行分类。(The program can train the constructed BP neural network through the training set, and can classify the different motion states through the test set.)
