Spatial-Temporal Alignment Network for Action Recognition and Detection
Junwei Liang, Liangliang Cao, Xuehan Xiong +2
This paper studies how to introduce viewpoint-invariant feature representations that can help action recognition and detection. Although we have witnessed great progress of action…
Event-Related Bias Removal for Real-time Disaster Events
Evangelia Spiliopoulou, Salvador Medina Maza, Eduard Hovy +1
Social media has become an important tool to share information about crisis events such as natural disasters and mass attacks. Detecting actionable posts that contain useful inform…
Support-set bottlenecks for video-text representation learning
Mandela Patrick, Po-Yao Huang, Yuki Asano +4
The dominant paradigm for learning video-text representations -- noise contrastive learning -- increases the similarity of the representations of pairs of samples that are known to…
Robust Long-Term Object Tracking via Improved Discriminative Model Prediction
Seokeon Choi, Junhyun Lee, Yunsung Lee +1
We propose an improved discriminative model prediction method for robust long-term tracking based on a pre-trained short-term tracker. The baseline pre-trained short-term tracker i…
From A Glance to "Gotcha": Interactive Facial Image Retrieval with Progressive Relevance Feedback
Xinru Yang, Haozhi Qi, Mingyang Li +1
Facial image retrieval plays a significant role in forensic investigations where an untrained witness tries to identify a suspect from a massive pool of images. However, due to the…
MSNet: A Multilevel Instance Segmentation Network for Natural Disaster Damage Assessment in Aerial Videos
Xiaoyu Zhu, Junwei Liang, Alexander Hauptmann
In this paper, we study the problem of efficiently assessing building damage after natural disasters like hurricanes, floods or fires, through aerial video analysis. We make two ma…
Unsupervised Multimodal Neural Machine Translation with Pseudo Visual Pivoting
Po-Yao Huang, Junjie Hu, Xiaojun Chang +1
Unsupervised machine translation (MT) has recently achieved impressive results with monolingual corpora only. However, it is still challenging to associate source-target sentences…
SimAug: Learning Robust Representations from Simulation for Trajectory Prediction
Junwei Liang, Lu Jiang, Alexander Hauptmann
This paper studies the problem of predicting future trajectories of people in unseen cameras of novel scenarios and views. We approach this problem through the real-data-free setti…
ZSTAD: Zero-Shot Temporal Activity Detection
Lingling Zhang, Xiaojun Chang, Jun Liu +4
An integral part of video analysis and surveillance is temporal activity detection, which means to simultaneously recognize and localize activities in long untrimmed videos. Curren…
Gun Source and Muzzle Head Detection
Zhong Zhou, Isak Czeresnia Etinger, Florian Metze +2
There is a surging need across the world for protection against gun violence. There are three main areas that we have identified as challenging in research that tries to curb gun v…
