Weakly-supervised Action Localization via Hierarchical Mining

no code implementations22 Jun 2022 Jia-Chang Feng, Fa-Ting Hong, Jia-Run Du, Zhongang Qi, Ying Shan, XiaoHu Qie, Wei-Shi Zheng, Jianping Wu

In this work, we propose a hierarchical mining strategy under video-level and snippet-level manners, i. e., hierarchical supervision and hierarchical consistency mining, to maximize the usage of the given annotations and prediction-wise consistency.

Cross-modal Consensus Network for Weakly Supervised Temporal Action Localization

1 code implementation27 Jul 2021 Fa-Ting Hong, Jia-Chang Feng, Dan Xu, Ying Shan, Wei-Shi Zheng

In this work, we argue that the features extracted from the pretrained extractor, e. g., I3D, are not the WS-TALtask-specific features, thus the feature re-calibration is needed for reducing the task-irrelevant information redundancy.
