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

tensorflow/models CVPR 2018

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

PaddlePaddle/models 26 Aug 2019

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

wei-tim/YOWO 15 Nov 2019

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

Alvin-Zeng/PGCN ICCV 2019

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

zhengshou/scnn CVPR 2016

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.

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.
