recommendations! Published in 2020 at "Digital Communications and Networks"

DOI: 10.1016/j.dcan.2020.05.004

Abstract: Abstract Most of the intelligent surveillances in the industry only care about the safety of the workers. It is meaningful if the camera can know what, where and how the worker has performed the action… read more here.

recommendations! Published in 2020 at "IEEE Access"

DOI: 10.1109/access.2019.2961789

Abstract: The Online Action Detection (OAD) problem needs to be revisited. Unlike traditional offline action detection approaches, where the evaluation metrics are clear and well established, in the OAD setting we find very few works and… read more here.

DOI: 10.1109/tcsvt.2025.3558939

Abstract: Spatiotemporal action detection localizes the action instances along both spatial and temporal dimensions, by identifying action start time and end time, action class, and object (e.g., actor) bounding boxes. It faces two primary challenges: 1)… read more here.

recommendations! Published in 2021 at "IEEE Transactions on Multimedia"

DOI: 10.1109/tmm.2020.3014555

Abstract: Inspired by Faster R-CNN, current state-of-the-art region-based action detection approaches like R-C3D and TAL-Net creatively proposed Temporal Region Proposal Network (TRPN) to generate proposals, which greatly improved action detection accuracy. However, since smooth L1 loss… read more here.
