Crowds flow like rivers

The Flow of Human Crowds

■ Abstract The modern study of a crowd as a flowing continuum is a recent development. Distinct from a classical fluid because of the property that a crowd has the capacity to think, interesting new physical ideas are involved in its study. An appealing property of a crowd in motion is that the nonlinear, time-dependent, simultaneous equations representing a crowd are conformably mappable. This...

Flow Segmentation in Dense Crowds

Now a day’s security is an important aspect to be considered, so a framework is proposed in this paper that is used to segment flow of dense crowds. The flow field that is generated by the movement in the crowd is treated just like an aperiodic dynamic system. On this flow field a grid of particles is put over for particle advection by the use of a numerical integration scheme. Then flow maps a...

Modeling of Flow in Watersheds and Rivers

Remote Monitoring of Subsurface Flow Conditions in Rivers

The primary research goal is to develop techniques to determine subsurface turbulence from remote measurements using infrared imaging of the skin layer. We aim to infer flow rate, turbulence intensity and subsurface-generated turbulent structures from surface temperature patterns. We will take advantage of the two complementary indicators of subsurface flow provided by IR imagery: the thermal s...

Semantic crowds

Recent advances in crowd simulation techniques have led to increasingly realistic agent and group behavior. As many crowd simulation solutions typically target only specific types of environments and scenarios, numerous special-purpose methods and systems have emerged that are unsuitable for other contexts. Solving this situation demands a higher-level approach that takes re-use and re-configur...
