Abstract: In this work, we tackle the problem of detecting “take” and “release” actions from egocentric videos. We address the task following a new Online Detection of Action End (ODAE) formulation in which algorithms have to determine the end of an action in an online fashion. We show that ODAE has advantages over previous formulations that focus on detecting actions at the contact frame or offline, thanks to the reduced uncertainty due to the complete observation of events before a prediction is made. We adapt to this task and benchmark different state-of-the-art temporal online action detection models on the EPIC-KITCHENS dataset, highlighting the specific challenges of the ODAE task, such as sparse annotations and high action density. Analysis on THUMOS14 shows that most conclusions are valid also in a third-person vision scenario. We also investigate the impact of techniques such as label propagation to address annotation imbalance. Our results show that the problem is far from being solv ed, Mamba-based models consistently outperform transformer-based models in all settings. (More)
