CONE: An Efficient COarse-to-fiNE Alignment Framework for Long Video Temporal Grounding

1 code implementation22 Sep 2022 Zhijian Hou, Wanjun Zhong, Lei Ji, Difei Gao, Kun Yan, Wing-Kwong Chan, Chong-Wah Ngo, Zheng Shou, Nan Duan

This paper tackles an emerging and challenging problem of long video temporal grounding~(VTG) that localizes video moments related to a natural language (NL) query.

Towards Train-Test Consistency for Semi-supervised Temporal Action Localization

no code implementations24 Oct 2019 Xudong Lin, Zheng Shou, Shih-Fu Chang

The inconsistent strategy makes it hard to explicitly supervise the action localization model with temporal boundary annotations at training time.

CDSA: Cross-Dimensional Self-Attention for Multivariate, Geo-tagged Time Series Imputation

2 code implementations23 May 2019 Jiawei Ma, Zheng Shou, Alireza Zareian, Hassan Mansour, Anthony Vetro, Shih-Fu Chang

In order to jointly capture the self-attention across multiple dimensions, including time, location and the sensor measurements, while maintain low computational complexity, we propose a novel approach called Cross-Dimensional Self-Attention (CDSA) to process each dimension sequentially, yet in an order-independent manner.

AutoLoc: Weakly-supervised Temporal Action Localization

1 code implementation22 Jul 2018 Zheng Shou, Hang Gao, Lei Zhang, Kazuyuki Miyazawa, Shih-Fu Chang

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

Single Shot Temporal Action Detection

2 code implementations17 Oct 2017 Tianwei Lin, Xu Zhao, Zheng Shou

The main drawback of this framework is that the boundaries of action instance proposals have been fixed during the classification step.

Temporal Action Localization in Untrimmed Videos via Multi-stage CNNs

1 code implementation CVPR 2016 Zheng Shou, Dongang Wang, Shih-Fu Chang

To address this challenging issue, we exploit the effectiveness of deep networks in temporal action localization via three segment-based 3D ConvNets: (1) a proposal network identifies candidate segments in a long video that may contain actions; (2) a classification network learns one-vs-all action classification model to serve as initialization for the localization network; and (3) a localization network fine-tunes on the learned classification network to localize each action instance.
