ACGNet: Action Complement Graph Network for Weakly-Supervised Temporal Action Localization

AAAI 2022technical

Weakly-supervised temporal action localization (WTAL) in untrimmed videos has emerged as a practical but challenging task since only video-level labels are available. Existing approaches typically leverage off-the-shelf segment-level features, which suffer from spatial incompleteness and temporal in…

Human-Aware Coarse-to-Fine Online Action Detection

Zichen Yang, Di Huang, Jie Qin, Yunhong Wang

ICASSP 2021accepted

In this work, we propose a two-stage framework to efficiently and effectively detect actions on-the-fly. An action location network (ALN) is developed in the first stage to judge whether the current frame is action-related, while the second stage involves an action classification network (ACN) to fu…
