HAGN: Hierarchical Attention Guided Network for Crowd Counting

open access: yesIEEE Access, 2020
In recent years, deep learning based crowd counting networks have achieved significant progress. However, most of them generate rough crowd density maps due to low-resolution features used for estimating crowd distribution, which affects the performance ...

Short-time existence of solutions for mean-field games with congestion [PDF]

open access: yes, 2015
We consider time-dependent mean-field games with congestion that are given by a system of a Hamilton-Jacobi equation coupled with a Fokker-Planck equation. The congestion effects make the Hamilton-Jacobi equation singular.

A Statistical Approach in Designing an RF-Based Human Crowd Density Estimation System

open access: yesInternational Journal of Distributed Sensor Networks, 2016
The study of human crowd density estimation (H-CDE) using radio frequency is limited due to the nature of wireless medium and the advancement of visual-based systems.

A system for efficient egress scheduling during mass events and small-scale experimental demonstration [PDF]

open access: yesRoyal Society Open Science, 2020
Improvements in the design of pedestrian facilities have reduced the frequency of crowd accidents, and safety is now generally ensured in well-planned crowd events. However, congestion and inefficient use of infrastructures still remain an issue.

DecideNet: Counting Varying Density Crowds Through Attention Guided Detection and Density Estimation

open access: yes, 2018
In real-world crowd counting applications, the crowd densities vary greatly in spatial and temporal domains. A detection based counting method will estimate crowds accurately in low density scenes, while its reliability in congested areas is downgraded ...

Crowd Counting in Diverse Environments Using a Deep Routing Mechanism Informed by Crowd Density Levels

open access: yesInformation
Automated crowd counting is a crucial aspect of surveillance, especially in the context of mass events attended by large populations. Traditional methods of manually counting the people attending an event are error-prone, necessitating the development of

Evolution models for mass transportation problems [PDF]

open access: yes, 2012
We present a survey on several mass transportation problems, in which a given mass dynamically moves from an initial configuration to a final one.
