Three Branches: Detecting Actions With Richer Features

13 Aug 2019

We present our three branch solutions for International Challenge on Activity Recognition at CVPR2019.

Submission to ActivityNet Challenge 2019: Task B Spatio-temporal Action Localization

25 Jul 2019

This technical report present an overview of our system proposed for the spatio-temporal action localization(SAL) task in ActivityNet Challenge 2019.

Trimmed Action Recognition, Dense-Captioning Events in Videos, and Spatio-temporal Action Localization with Focus on ActivityNet Challenge 2019

14 Jun 2019

This notebook paper presents an overview and comparative analysis of our systems designed for the following three tasks in ActivityNet Challenge 2019: trimmed action recognition, dense-captioning events in videos, and spatio-temporal action localization.

Improving Action Localization by Progressive Cross-Stream Cooperation

CVPR 2019

To improve action localization results at the video level, we additionally propose a new strategy to train class-specific actionness detectors for better temporal segmentation, which can be readily learnt by using the training samples around temporal boundaries.

Improving Action Localization by Progressive Cross-stream Cooperation

CVPR 2019

Specifically, we first generate a larger set of region proposals by combining the latest region proposals from both streams, from which we can readily obtain a larger set of labelled training samples to help learn better action detection models.

Spatio-Temporal Action Localization in a Weakly Supervised Setting

6 May 2019

Enabling computational systems with the ability to localize actions in video-based content has manifold applications.

Actor-Centric Relation Network

ECCV 2018

A visualization of the learned relation features confirms that our approach is able to attend to the relevant relations for each action.

Spatio-Temporal Instance Learning: Action Tubes from Class Supervision

8 Jul 2018

Rather than disconnecting the spatio-temporal learning from the training, we propose Spatio-Temporal Instance Learning, which enables action localization directly from box proposals in video frames.

YH Technologies at ActivityNet Challenge 2018

29 Jun 2018

This notebook paper presents an overview and comparative analysis of our systems designed for the following five tasks in ActivityNet Challenge 2018: temporal action proposals, temporal action localization, dense-captioning events in videos, trimmed action recognition, and spatio-temporal action localization.

Modeling Spatio-Temporal Human Track Structure for Action Localization

28 Jun 2018

In order to localize actions in time, we propose a recurrent localization network (RecLNet) designed to model the temporal structure of actions on the level of person tracks.
