Human Action Recognition by Representing 3D Skeletons as Points in a Lie Group
Raviteja Vemulapalli,Felipe Arrate,Rama Chellappa +2 more
- 23 Jun 2014
TL;DR: A new skeletal representation that explicitly models the 3D geometric relationships between various body parts using rotations and translations in 3D space is proposed and outperforms various state-of-the-art skeleton-based human action recognition approaches.

Frame-Recurrent Video Super-Resolution
Mehdi S. M. Sajjadi,Raviteja Vemulapalli,Matthew Brown +2 more
- 02 Jan 2018
TL;DR: In this paper, an end-to-end trainable frame-recurrent video super-resolution framework was proposed that uses the previously inferred HR estimate to super-resolve the subsequent frame.
Rolling Rotations for Recognizing Human Actions from 3D Skeletal Data
Raviteja Vemulapalli,Rama Chellappa +1 more
- 01 Jun 2016
TL;DR: This work uses rolling maps for recognizing human actions from 3D skeletal data and unwrap the action curves onto the Lie algebra so3 × ... × so3 (which is a vector space) by combining the logarithm map with rolling maps, and perform classification in the Liegebra.

Contrastive Learning for Label-Efficient Semantic Segmentation
Xiangyun Zhao,Raviteja Vemulapalli,Philip Andrew Mansfield,Boqing Gong,Bradley Ray Green,Lior Shapira,Ying Wu +6 more
TL;DR: A simple and effective contrastive learning-based training strategy in which the network is pretrain the network using a pixel-wise, label-based contrastive loss, and then fine-tune it using the cross-entropy loss, which increases intra-class compactness and inter-class separability, thereby resulting in a better pixel classifier.

Gaussian Conditional Random Field Network for Semantic Segmentation
Raviteja Vemulapalli,Oncel Tuzel,Ming-Yu Liu,Rama Chellappa +3 more
- 27 Jun 2016
TL;DR: A novel deep network, which is referred to as Gaussian Mean Field (GMF) network, whose layers perform mean field inference over a Gaussian CRF, which outperforms various recent semantic segmentation approaches that combine CNNs with discrete CRF models.
