DVANet: Disentangling View and Action Features for Multi-View Action Recognition

no code implementations10 Dec 2023 Nyle Siddiqui, Praveen Tirupattur, Mubarak Shah

In this work, we present a novel approach to multi-view action recognition where we guide learned action representations to be separated from view-relevant information in a video.

TinyAction Challenge: Recognizing Real-world Low-resolution Activities in Videos

1 code implementation24 Jul 2021 Praveen Tirupattur, Aayush J Rana, Tushar Sangam, Shruti Vyas, Yogesh S Rawat, Mubarak Shah

While various approaches have been shown effective for recognition task in recent works, they often do not deal with videos of lower resolution where the action is happening in a tiny region.

Modeling Multi-Label Action Dependencies for Temporal Action Localization

1 code implementation CVPR 2021 Praveen Tirupattur, Kevin Duarte, Yogesh Rawat, Mubarak Shah

We propose to improve action localization performance by modeling these action dependencies in a novel attention-based Multi-Label Action Dependency (MLAD)layer.

Gabriella: An Online System for Real-Time Activity Detection in Untrimmed Security Videos

no code implementations23 Apr 2020 Mamshad Nayeem Rizve, Ugur Demir, Praveen Tirupattur, Aayush Jung Rana, Kevin Duarte, Ishan Dave, Yogesh Singh Rawat, Mubarak Shah

For tubelet extraction, we propose a localization network which takes a video clip as input and spatio-temporally detects potential foreground regions at multiple scales to generate action tubelets.
