We present a novel automated technique for the quantitative validation and comparison of multi-agent based crowd egress simulation systems. Despite much progress in the simulation technology itself, little attention has been accorded to the problem of validating these systems against reality. Previous approaches focused on local (spatial or temporal) crowd patterns, and either resorted to visua...

Crowd simulations are becoming increasingly important for public authorities and researchers. The film and video game industry have been developing and using tools for crowd simulations for decades. The Maya plugin Miarmy is such a tool, but it was not designed specifically for scientific purposes. We perform experiments in Miarmy to test its functionality. Simple scenes can be set up, simulate...

We present a framework for video-driven crowd synthesis. Motion vectors extracted from input crowd video are processed to compute global motion paths. These paths encode the dominant motions observed in the input video. These paths are then fed into a behavior-based crowd simulation framework, which is responsible for synthesizing crowd animations that respect the motion patterns observed in th...

Crowd modeling and simulation is an important and active research field, with a wide range of applications such as computer games, military training and evacuation modeling. One important issue in crowd modeling is model calibration through parameter tuning, so as to produce desired crowd behaviors. Common methods such as trial-and-error are time consuming and tedious. This paper proposes an ev...

This paper investigates the problem of protesting crowd simulation. It considers CROCADILE, an agent based distillation system, for this purpose. A model of protesting crowd was determined and then a CROCADILE model of protesting crowd was engineered and demonstrated. We validated the model by using two scenarios where protesters are varied with different personalities. The results indicated th...

Crowds of non-combatants play a large and increasingly recognized role in modern military operations, and often create substantial difficulties for the combatant forces involved. U. S. military actions in Mogadishu, Bosnia, and Iraq exemplify the significant effects crowds may have on military operations. However, in spite of their potential significance, realistic models of crowds are essentia...

The paper describes a Multi-Agent approach to crowd modeling and simulation. After a brief introduction of the Situated Cellular Agents model, the guidelines to the crowd modeling approach is introduced as a way to support the communication among the different actors that are part of the simulation project team. The approach is then applied to describe a complex scenario providing a blend of co...

The addition of a crowd in a virtual environment, such as a game world, can make the environment more realistic. While researchers focused on the visual modeling and simulation of a crowd, its sound production has received less attention. We propose the generation of the sound of a crowd by retrieving a very small set of speech snippets from a user-contributed database, and transforming and lay...

We present a new civilian crowd simulator for the Robocup Rescue Simulation that allows to represent large numbers of civilians and in which psychologically and socially plausible crowd behavior emerges. As a new challenge for the Rescue Simulation competition, the simulator also allows police agents to indirectly influence crowd behavior by temporarily blocking roads. The simulator can be used...

Crowd simulation is becoming indispensable in computer games and animations. Several approaches to this problem have succeeded in generating flocking behaviors with virtual forces but it remains difficult to manipulate the collective behaviors of a crowd to respect certain desired shape. In this paper, we propose a crowd simulation system that can generate a feasible path taking the crowd to th...
