摘要:

团队运动分析的要求之一是跟踪和识别球员。在视频监控的背景下,已经提出了许多跟踪和重新识别方法。当在公共数据集(如MOT挑战)上进行测试时,它们显示出非常令人信服的结果。然而,这些方法的性能并不令人满意时,应用于球员跟踪。事实上,除了移动速度非常快而且经常被遮挡之外,球员们还穿着同样的球衣,这使得重新识别的任务非常复杂。一些最近的跟踪方法已经开发出更具体的团队运动的背景下。由于缺乏公共数据,这些方法使用私人数据集,无法与它们进行比较。在本文中,我们提出了一种新的通用方法来跟踪团队运动员在一个完整的游戏由于通过半交互式系统收集的人类注释很少。无歧义的tracklet及其外观特征是通过检测和重新识别网络自动生成的,这两个网络都是在公共数据集上预先训练的。然后,增量学习机制训练Transformer使用很少的游戏特定的人类注释对身份进行分类。最后,tracklet通过关联算法连接。我们证明了我们的方法在一个具有挑战性的七人制橄榄球数据集的效率。为了克服缺乏公共体育跟踪数据集的问题,我们在https://kalisteo.cea.fr/index.php/free-resources/上公开发布了这个数据集。我们还表明,我们的方法是能够跟踪橄榄球七人制球员在一个完整的比赛中,如果他们是在一个最小的分辨率,只有6个几秒长的tracklets每个球员的注释观察。

英文摘要:

One of the requirements for team sports analysis is to track and recognize players. Many tracking and reidentification methods have been proposed in the context of video surveillance. They show very convincing results when tested on public datasets such as the MOT challenge. However, the performance of these methods are not as satisfactory when applied to player tracking. Indeed, in addition to moving very quickly and often being occluded, the players wear the same jersey, which makes the task of reidentification very complex. Some recent tracking methods have been developed more specifically for the team sport context. Due to the lack of public data, these methods use private datasets that make impossible a comparison with them. In this paper, we propose a new generic method to track team sport players during a full game thanks to few human annotations collected via a semi-interactive system. Non-ambiguous tracklets and their appearance features are automatically generated with a detection and a reidentification network both pre-trained on public datasets. Then an incremental learning mechanism trains a Transformer to classify identities using few game-specific human annotations. Finally, tracklets are linked by an association algorithm. We demonstrate the efficiency of our approach on a challenging rugby sevens dataset. To overcome the lack of public sports tracking dataset, we publicly release this dataset at https://kalisteo.cea.fr/index.php/free-resources/. We also show that our method is able to track rugby sevens players during a full match, if they are observable at a minimal resolution, with the annotation of only 6 few seconds length tracklets per player.
