WebDGAM [18]. The following two lines are the ground truth of action localization and localization results in DGAM [18]. As shown in the figure, there is a small difference between the weights of some background regions and action regions. During action localization, these background regions are also selected, which are the red regions in … WebCompleteness Modeling and Context Separation for Weakly Supervised Temporal Action Localization. Finspire13/CMCS-Temporal-Action-Localization • • CVPR 2024. In this work, we first identify two underexplored problems posed by the weak supervision for temporal action localization, namely action completeness modeling and action-context ...
WebMar 30, 2024 · Weakly-supervised temporal action localization (WS-TAL) aims to localize actions in untrimmed videos with only video-level labels. Most existing models follow the "localization by classification" procedure: locate temporal regions contributing most to the video-level classification. Generally, they process each snippet (or frame) individually ... WebThere has been remarkable progress in fully-supervised tem-poral action localization (Tran et al.2024;Zhao et al.2024; Chao et al.2024;Lin et al.2024;Xu et al.2024). However, annotating the precise temporal ranges of all action instances in a video dataset is expensive, time-consuming, and error-prone. On the contrary, weakly supervised ...
