Event Detection in Crowded Videos

Yan Ke, Rahul Sukthankar, Martial Hebert
2007 2007 IEEE 11th International Conference on Computer Vision  
We propose a technique for event recognition in crowded videos that reliably identifies actions in the presence of partial occlusion and background clutter.  ...  This poses a difficult challenge for current approaches to video event detection because it is difficult to segment the actor from the background due to distracting motion from other objects in the scene  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.  ...

Toward Crowd-Sensitive Path Planning [article]

Anoop Aroor, Susan L. Epstein
2017 arXiv   pre-print
If a robot can predict crowds in parts of its environment that are inaccessible to its sensors, then it can plan to avoid them.  ...  In simulation across multiple challenging crowd scenarios, the robot reaches its target faster, travels less, and risks fewer collisions than if it were to plan with the traditional A* algorithm.  ...  Acknowledgements This work was supported in part by NSF #1625843.  ...
