Learning Extremely High Density Crowds as Active Matters
Feixiang He, Jiangbei Yue, Jialin Zhu +4
Video-based high-density crowd analysis and prediction has been a long-standing topic in computer vision. It is notoriously difficult due to, but not limited to, the lack of high-q…
Pedestrian Flow Analysis in High-Density Crowds: Continuity Equation with Voronoi-Based Fields
Juliane Adrian, Ann Katrin Boomers, Sarah Paetzke +1
Since the beginning of the century, capturing trajectories of pedestrian streams precisely from video recordings has been possible. To enable measurements at high density, the head…
Human Motion Prediction under Unexpected Perturbation
Jiangbei Yue, Baiyi Li, Julien Pettré +2
We investigate a new task in human motion prediction, which is predicting motions under unexpected physical perturbation potentially involving multiple people. Compared with existi…
Temporal segmentation of motion propagation in response to an external impulse
Sina Feldmann, Thomas Chatagnon, Juliane Adrian +2
In high-density crowds, local motion can propagate, amplify, and lead to macroscopic phenomena, including 'density waves'. These density waves only occur when individuals interact,…
