The LETSCROWD Server presents and integrates a set of innovative tools with the aim of improving citizen security in events of massive concurrence.
Crowd counting and density estimation – Human Centred Computer Vision Tool (HCV) – LETSCROWD Tool Videos #7
The “Crowd counting and density estimation” is useful for real-time estimation of crowd size and detection of related anomalous behaviours, e.g.: overcrowding with respect to an user-defined threshold, sudden increase or decrease of crowd size.
The “Attribute-based people search” allows to search in several recorded videos for individuals who match an attribute profile of clothing appearance (e.g., colours), gender, carried items.
The “appearance-based person re-identification” allows to search for an individual of interest in several recorded videos, based on clothing appearance, using an image as a query.
The CMPT is a collection of advanced crowd simulations that allow enforcement agencies to analyse crowd behavior at mass gatherings for planning, training or operational uses.
The tool performs hundreds of simulations for the same scenario to capture all potential outcomes. The outputs are the total evacuation times, the evacuation times per exit and the exit use.
The Semantic Intelligence Engine (SIE) tools allows gathering, monitoring and analyzing information published in the Web about a mass gathering before and during a given event.
