Graph Convolutional Networks for Temporal Action Localization

7 Sep 2019Alvin-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.

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

22 Aug 2019naraysa/3c-net

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.

Temporal Unet: Sample Level Human Action Recognition using WiFi

19 Apr 2019geekfeiw/WiSLAR

In this task, every WiFi distortion sample in the whole series should be categorized into one action, which is a critical technique in precise action localization, continuous action segmentation, and real-time action recognition.

Guess Where? Actor-Supervision for Spatiotemporal Action Localization

5 Apr 2018escorciav/roi_pooling

Second, we propose an actor-based attention mechanism that enables the localization of the actions from action class labels and actor proposals and is end-to-end trainable.

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.
