摘要:

人员重新识别在监控应用中至关重要。目前的方法依赖于从目标和候选匹配的单个或多个镜头中提取的基于外观的特征。这些方法在试图区分穿着相似颜色的候选人或目标改变服装时处于不利地位。在本文中,我们提出了一个基于动态的功能,以克服这一限制。其主要思想是通过收集密集的短轨迹(tracklets),这是费舍尔矢量编码的步态和运动模式捕获软生物特征。为了说明所提出的功能的优点,我们介绍了三个新的“外观受损”的数据集。我们对原始数据集和外观受损数据集的实验证明了将基于动态的信息与基于外观的信息结合到重新识别算法中的好处。

英文摘要:

Person re-identification is critical in surveillance applications. Current approaches rely on appearance based features extracted from a single or multiple shots of the target and candidate matches. These approaches are at a disadvantage when trying to distinguish between candidates dressed in similar colors or when targets change their clothing. In this paper we propose a dynamics-based feature to overcome this limitation. The main idea is to capture soft biometrics from gait and motion patterns by gathering dense short trajectories (tracklets) which are Fisher vector encoded. To illustrate the merits of the proposed features we introduce three new "appearance-impaired" datasets. Our experiments on the original and the appearance impaired datasets demonstrate the benefits of incorporating dynamics-based information with appearance-based information to re-identification algorithms.
