Introduction

- OATS dataset uses a novel representation called Ordered Atomic Activity for interactive scenario understanding. The representation decomposes each scenario into a set of ordered atomic activities, where each activity consists of an action and the corresponding actors involved and the order denotes the temporal development of the scenario. This design also helps in identifying important interactive relationships, such as yielding. The action is a high-level semantic motion pattern that is grounded in the surrounding road topology, which we decompose into zones and corners with unique IDs.

-The OATS dataset comprises of 1026 video clips (∼ 20s) captured at intersections in San Francisco Bay Area. Each clip is labeled with the proposed language, resulting in 59 activity categories and 6512 annotated activity instances with a resolution of 1920×1200 and a frame rate of 10 fps.
