Vortex Tracking in Scale-Space

چکیده
Automatic extraction of features is a promising strategy to cope with the large amount of data produced by time-dependent CFD (computational fluid dynamics) simulations. Computation time for this type of simulations is typically in the order of days, which justifies the time spent on post-processing the data by extracting features in a batch run. Automatic feature extraction can achieve data reductions of up to 1:10000 [4] while still permitting the visualization of essential parts of the flow. It can be used for visually browsing through the datasets or it can be combined with other types of visualization. However, the implementation of this strategy leads to the following problems:

2D Numerical Simulation of a Micro Scale Ranque-Hilsch Vortex Tube
In this study, fluid flow and energy separation in a micro-scale Ranque-HilschVortex Tube are numerically investigated. The flow is assumed as 2D, steady,compressible ideal gas, and shear-stress-transport SST k-W is found to be a bestchoice for modeling of turbulence phenomena. The results are in a good agreementwith the experimental results reported in the literature. The results show that f...
متن کاملExtracting, Tracking and Visualizing Vortices in 3D Complex-Valued Superconductor Simulation Data
We propose a unified method for the analytically exact vortex extraction and tracking of superconducting magnetic flux vortices for both structured and unstructured mesh data. In the Ginzburg-Landau theory, magnetic flux vortices are well-defined features in a complex-valued order parameter field, and their dynamics determine electromagnetic properties in type-II superconductors. Our method rep...
متن کاملNumerical Investigation of Vortex Interaction in Pipe Flow
To discover the nonlinear characteristics of pipe flow, we simulated the flow as a sum of many vortex rings. As a first step, we investigated the nonlinear interaction among a maximum of three vortex rings. The pipe wall was replaced by many bound vortices. A free vortex ring moves right or left according to the radius, and that of a particular radius keeps the initial position. The energy of a...
متن کاملScale-Space Tracking of Critical Points in 3D Vector Fields
Scale-space techniques are very popular in image processing since they allow for the integrated analysis of image structure. The multi-scale approach enables one to distinguish between important features such as edges and smallscale features such as numerical artifacts or noise. In general, the same properties hold for vector fields such as flow data. Many flow features, e.g. vortices, can be o...

With the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. Therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. Tracking people as they move through a camera network with non-overlapping field...
