AI总结:

本文提出一种理论方法,用于总结多个视频的性能,保留性能指标间的关系,并提供计算公式和算法,通过CDNET 2014展示结果。

摘要:

现有许多背景减除算法用于检测视频中的运动。为了帮助比较,已提出具有真实数据集的CDNET或LASIESTA等数据集。这些数据集将视频分为代表背景减除典型挑战的类别。其作者推广的评估程序是分别测量每个视频的性能指标并逐层平均,先在类别内,然后在类别间,这一过程我们称为“总结”。虽然通过平均性能指标进行总结是标准化评估程序的有价值的尝试,但缺乏理论依据且破坏了汇总指标之间的内在关系。这导致了解释不一致。在本文中,我们提出了一种理论方法来总结多个视频的性能,以保持性能指标之间的关系。此外,我们还给出了计算汇总性能的公式和算法。最后,我们通过CDNET 2014展示了我们的观察结果。

英文摘要:

There exist many background subtraction algorithms to detect motion in videos. To help comparing them, datasets with ground-truth data such as CDNET or LASIESTA have been proposed. These datasets organize videos in categories that represent typical challenges for background subtraction. The evaluation procedure promoted by their authors consists in measuring performance indicators for each video separately and to average them hierarchically, within a category first, then between categories, a procedure which we name "summarization". While the summarization by averaging performance indicators is a valuable effort to standardize the evaluation procedure, it has no theoretical justification and it breaks the intrinsic relationships between summarized indicators. This leads to interpretation inconsistencies. In this paper, we present a theoretical approach to summarize the performances for multiple videos that preserves the relationships between performance indicators. In addition, we give formulas and an algorithm to calculate summarized performances. Finally, we showcase our observations on CDNET 2014.
