Background Suppression Network for Weakly-supervised Temporal Action Localization

Pilhyeon/BaSNet-pytorch 22 Nov 2019

This formulation does not fully model the problem in that background frames are forced to be misclassified as action classes to predict video-level labels accurately.

Weakly-supervised Temporal Action Localization by Uncertainty Modeling

Pilhyeon/WTAL-Uncertainty-Modeling 12 Jun 2020

Experimental results show that our uncertainty modeling is effective at alleviating the interference of background frames and brings a large performance gain without bells and whistles.

AutoLoc: Weakly-supervised Temporal Action Localization

zhengshou/AutoLoc 22 Jul 2018

In this paper, we first develop a novel weakly-supervised TAL framework called AutoLoc to directly predict the temporal boundary of each action instance.

3C-Net: Category Count and Center Loss for Weakly-Supervised Action Localization

naraysa/3c-net ICCV 2019

Our joint formulation has three terms: a classification term to ensure the separability of learned action features, an adapted multi-label center loss term to enhance the action feature discriminability and a counting loss term to delineate adjacent action sequences, leading to improved localization.

Learning Action Completeness from Points for Weakly-supervised Temporal Action Localization

Pilhyeon/Learning-Action-Completeness-from-Points 11 Aug 2021

To learn completeness from the obtained sequence, we introduce two novel losses that contrast action instances with background ones in terms of action score and feature similarity, respectively.

Weakly Supervised Temporal Action Localization Using Deep Metric Learning

asrafulashiq/wsad 21 Jan 2020

We propose a classification module to generate action labels for each segment in the video, and a deep metric learning module to learn the similarity between different action instances.
