本文针对MS跟踪和粒子滤波跟踪各自的优缺点，将其两者进行了很好地结合，提出了两步跟踪算法，其特点有：保留了MS跟踪实时性的优点的同时，也具有粒子滤波在遮挡情况下的鲁棒性等特点；在所需的每步粒子跟踪中，以上一步的跟踪结果与模板的相似度为先验知识，自适应地选取粒子个数和传播半径，缓解了粒子缺乏多样性的缺点，也根据这个相似度来判断是否需要对目标模板的更新，保证了更新的有效性。

In comparison with π-conjugated polymers, mono- disperse conjugated oligomers possessing well-defined con- jugation lengths and structural models are characterized by the uniformity, absence of chain defects, and ease of purification and characterization, which make them superior to CPs for systematic investigation of the structure-property relationships.2

Grant trades once again on his irresistibly clumsy, self-deprecating charm, but Roberts not only gets another great role in the genre where she's done her best work, she also gets to mock the Event Film and her own celebrity by playing Anna as an overpaid, mediocre and not entirely stable actress, who recognizes her shortcomings but hopes to someday star in something better than sci-fi extravaganzas and submarine thrillers in which she has to "save the world in 20 minutes."
