简介：因为在哪个录像运动需要被追踪，环境广泛地基于申请被改变并且在追踪的系统的设计和表演上提出几限制，录像追踪是一个复杂问题。没有彻底地分析环境强加的这些不同限制的效果，被用来评估并且比较录像运动追踪算法的当前的数据集使用一项累积性能措施。但是它需要作为参数分析这些限制。这份报纸的目的是识别这些参数并且定义量的措施让这些参数为运动追踪比较录像数据集。

简介：为在目标之中为相互作用建模的一个典型Markov网络能处理错误合并问题，而是它在合作追踪者之中由于盲目比赛受不了标记的问题。在这篇论文，我们为追踪的多目标建议一个运动限制Markov网络模型。由扩充典型Markov，有特定的Markov的网络锁住哪个带动议限制优先，这个建议模型能克服盲目比赛并且甚至在严重吸藏的情况中指导标签到相应目标。另外，运动限制优先作为本地潜在的功能被提出并且能容易在新奇模型的联合分发表示被合并。试验性的结果证明我们的模型比在解决错误的另外的方法优异合并并且同时并且高效地把问题标记。
