AVA: A Video Dataset of Spatio-temporally Localized Atomic Visual Actions

CVPR 2018 tensorflow/models

The AVA dataset densely annotates 80 atomic visual actions in 430 15-minute video clips, where actions are localized in space and time, resulting in 1. 58M action labels with multiple labels per person occurring frequently.

Deep Concept-wise Temporal Convolutional Networks for Action Localization

26 Aug 2019PaddlePaddle/models

In this paper, we empirically find that stacking more conventional temporal convolution layers actually deteriorates action classification performance, possibly ascribing to that all channels of 1D feature map, which generally are highly abstract and can be regarded as latent concepts, are excessively recombined in temporal convolution.

You Only Watch Once: A Unified CNN Architecture for Real-Time Spatiotemporal Action Localization

15 Nov 2019wei-tim/YOWO

YOWO is a single-stage architecture with two branches to extract temporal and spatial information concurrently and predict bounding boxes and action probabilities directly from video clips in one evaluation.

Graph Convolutional Networks for Temporal Action Localization

ICCV 2019 Alvin-Zeng/PGCN

Then we apply the GCNs over the graph to model the relations among different proposals and learn powerful representations for the action classification and localization.

Temporal Action Localization in Untrimmed Videos via Multi-stage CNNs

CVPR 2016 zhengshou/scnn

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.

HACS: Human Action Clips and Segments Dataset for Recognition and Temporal Localization

ICCV 2019 hangzhaomit/HACS-dataset

This paper presents a new large-scale dataset for recognition and temporal localization of human actions collected from Web videos.

Learning Sparse 2D Temporal Adjacent Networks for Temporal Action Localization

8 Dec 2019microsoft/2D-TAN

In this report, we introduce the Winner method for HACS Temporal Action Localization Challenge 2019.

Background Suppression Network for Weakly-supervised Temporal Action Localization

22 Nov 2019Pilhyeon/BaSNet-pytorch

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.

Completeness Modeling and Context Separation for Weakly Supervised Temporal Action Localization

CVPR 2019 Finspire13/CMCS-Temporal-Action-Localization

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 separation.
