The control of dense crowd is a time-consuming and challenging task. There are always conflicts between detailed movements and the control of large-scale crowd. To solve this problem, we suggest the smoothed particle hydrodynamics (SPH) technique to express continuous flow with two authorable interfaces. To reflect the connectivity that occurs in a crowd, we use an authorable sociogram model. A...

Crowd density estimation is very important in intelligent crowd monitoring. In this paper, a new approach of crowed density estimation is proposed. This method combines the advantage of pixel statistical feature and texture analysis, and reduces the impact of perspective distortion by dividing the region of interest. Moreover, we estimate the crowd size (the range of numbers) for high density a...

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...

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...

Crowds occur frequently, usually without serious problems. Occasionally venue inadequacies and deficient crowd management result in injuries and fatalities. Major crowd incidents are described. Extreme crowding results in individual loss of control, and both psychological and physiological problems. A simple model with the acronym "FIST" is proposed to provide a basic understanding of crowd dis...

This paper proposes a generic data-driven crowd modeling framework to generate crowd behaviors that can match the video data. The proposed framework uses a dual-layer mechanism to model the crowd behaviors. The bottom layer models the microscopic collision avoidance behaviors, while the top layer models the macroscopic crowd behaviors such as the goal selection patterns and the path navigation ...

translating and translation are transformed with information and communication technology (ict). within three decades, a new work environment is shaking up the translator’s world. new types of translators are emerging. the balance between supply and demand is changing. however, we need adequate tools and methods to investigate the new hierarchy which has become established between translators, ...

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...
