ISI Atomic Pair Actions Dataset

Understanding pair-wise activities is an essential step towards studying complex group and crowd behaviors in video. However, such research is often hampered by a lack of datasets that concentrate specifically on Atomic Pair Actions. In this paper, we introduce the ISI Atomic Pair Actions dataset, a set of 90 videos that concentrate on the Atomic Pair Actions of objects in video, namely converging, diverging, and moving in parallel. In addition, we make the full dataset (the videos, along with their associated tracks and ground truth) publicly available to the research community for free use and extension at <http://research.sethi.org/ricky/datasets/>.解析成对交互行为，是研究视频中复杂群体与人群行为的核心前提。然而，此类研究常因缺乏专门聚焦于原子成对动作（Atomic Pair Actions）的数据集而受阻。本文提出ISI原子成对动作数据集，该数据集包含90段视频，聚焦于视频内物体的原子成对动作，具体涵盖聚合、分散与并行移动三类。此外，本数据集的完整资源（含视频、关联跟踪轨迹与真实标注（ground truth））已面向科研社区免费开放，可供自由使用与拓展，获取链接为<http://research.sethi.org/ricky/datasets/>。
