Epidemic Intelligence for the Crowd, by the Crowd

Proceedings of the International AAAI Conference on Web and Social Media, 2021
Tracking Twitter for public health has shown great potential. However, most recent work has been focused on correlating Twitter messages to influenza rates, a disease that exhibits a marked seasonal pattern. In the presence of sudden outbreaks, how can social media streams be used to strengthen surveillance capacity?

Robust pedestrian detection and tracking in crowded scenes [PDF]

, 2009
In this paper, a robust computer vision approach to detecting and tracking pedestrians in unconstrained crowded scenes is presented. Pedestrian detection is performed via a 3D clustering process within a region-growing framework.

Epidemic Intelligence: For the Crowd, by the Crowd [PDF]

, 2012
Event Based Epidemic Intelligence (e-EI) encompasses activities related to early warnings and their assessments as part of the outbreak investigation task. Recently, modern disease surveillance systems have started to also monitor social media streams, with the objective of improving their timeliness in detecting disease outbreaks, and producing ...

Improving Multiple Pedestrian Tracking in Crowded Scenes with Hierarchical Association

Entropy, 2023
Recently, advances in detection and re-identification techniques have significantly boosted tracking-by-detection-based multi-pedestrian tracking (MPT) methods and made MPT a great success in most easy scenes. Several very recent works point out that the
