( 2 ) two experiments for this system are done : one is about system accuracy testing , another is label - based human motion analysis . ( 3 ) in active contour based tracking , segmentation and tracking of video moving object is used for guiding the extraction of video object plane from the video sequence . this dissertation describes spatio - temporal information to automatically segment and track video moving objects ( 2 )对这个系统进行实验测试和结果分析;首先进行了系统精度测试实验,结果表明此系统可以用于人体运动分析,然后进行了有标志点人体运动分析的实验测试,方法是将标志点贴在手腕上进行运动,结果得到手腕运动的三维运动轨迹,最后进行结果分析。
