Boundary Content Graph Neural Network for Temporal Action Proposal Generation

4 Aug 2020

To address this issue, we propose a novel Boundary Content Graph Neural Network (BC-GNN) to model the insightful relations between the boundary and action content of temporal proposals by the graph neural networks.

Learning to Discriminate Information for Online Action Detection

CVPR 2020

For online action detection, in this paper, we propose a novel recurrent unit to explicitly discriminate the information relevant to an ongoing action from others.
