G-VAE, a Geometric Convolutional VAE for ProteinStructure Generation
Hao Huang, Boulbaba Ben Amor, Xichan Lin +2
Analyzing the structure of proteins is a key part of understanding their functions and thus their role in biology at the molecular level. In addition, design new proteins in a meth…
Residual Networks as Flows of Velocity Fields for Diffeomorphic Time Series Alignment
Hao Huang, Boulbaba Ben Amor, Xichan Lin +2
Non-linear (large) time warping is a challenging source of nuisance in time-series analysis. In this paper, we propose a novel diffeomorphic temporal transformer network for both p…
Magnifying Subtle Facial Motions for Effective 4D Expression Recognition
Qingkai Zhen, Di Huang, Yunhong Wang +3
In this paper, an effective pipeline to automatic 4D Facial Expression Recognition (4D FER) is proposed. It combines two growing but disparate ideas in Computer Vision -- computing…
Sparse Coding of Shape Trajectories for Facial Expression and Action Recognition
Amor Ben Tanfous, Hassen Drira, Boulbaba Ben Amor
The detection and tracking of human landmarks in video streams has gained in reliability partly due to the availability of affordable RGB-D sensors. The analysis of such time-varyi…
A Novel Geometric Framework on Gram Matrix Trajectories for Human Behavior Understanding
Anis Kacem, Mohamed Daoudi, Boulbaba Ben Amor +2
In this paper, we propose a novel space-time geometric representation of human landmark configurations and derive tools for comparison and classification. We model the temporal evo…
