Home Action Genome: Cooperative Compositional Action Understanding
Nishant Rai, Haofeng Chen, Jingwei Ji +5
Existing research on action recognition treats activities as monolithic events occurring in videos. Recently, the benefits of formulating actions as a combination of atomic-actions…
Weak Multi-View Supervision for Surface Mapping Estimation
Nishant Rai, Aidas Liaudanskas, Srinivas Rao +3
We propose a weakly-supervised multi-view learning approach to learn category-specific surface mapping without dense annotations. We learn the underlying surface geometry of common…
CoCon: Cooperative-Contrastive Learning
Nishant Rai, Ehsan Adeli, Kuan-Hui Lee +2
Labeling videos at scale is impractical. Consequently, self-supervised visual representation learning is key for efficient video analysis. Recent success in learning image represen…
AdaScan: Adaptive Scan Pooling in Deep Convolutional Neural Networks for Human Action Recognition in Videos
Amlan Kar, Nishant Rai, Karan Sikka +1
We propose a novel method for temporally pooling frames in a video for the task of human action recognition. The method is motivated by the observation that there are only a small…
