Context-Aware RCNN: A Baseline for Action Detection in Videos

Jianchao Wu, Zhanghui Kuang, Limin Wang, Wayne Zhang, Gangshan Wu

ECCV 2020poster

Video action detection approaches usually conduct actor-centric action recognition over RoI-pooled features following the standard pipeline of Faster-RCNN. In this work, we first empirically find the recognition accuracy is highly correlated with the bounding box size of an actor, and thus higher re…

Learning Actor Relation Graphs for Group Activity Recognition

Jianchao Wu, Limin Wang, Li Wang, Jie Guo, Gangshan Wu

CVPR 2019poster

Modeling relation between actors is important for recognizing group activity in a multi-person scene. This paper aims at learning discriminative relation between actors efficiently using deep models. To this end, we propose to build a flexible and efficient \rm Actor Relation Graph (ARG) to simult…
