Clustering motion trajectories via dominant sets

2016 24th Signal Processing and Communication Application Conference (SIU), 2016
In recent years, video surveillance systems stand out as an important research topic in the field of computer vision. Studies in this context usually focus on detecting common motion patterns in video sequences, determining unexpected motions or predicting possible future events.

RESTRICTED SETS OF TRAJECTORIES AND DECIDABILITY OF SHUFFLE DECOMPOSITIONS

International Journal of Foundations of Computer Science, 2005
The decidability of the shuffle decomposition problem for regular languages is a long standing open question. We consider decompositions of regular languages with respect to shuffle along a regular set of trajectories and obtain positive decidability results for restricted classes of trajectories.

Simplex-Like Trajectories on Quasi-Polyhedral Sets

Mathematics of Operations Research, 2001
This paper presents a unified treatment of two new simplex-like methods for linear semi-infinite programming problems with quasi-polyhedral feasible sets. The simplex method combines a purification phase I (which provides an extreme point from a given feasible solution) with the iterative application of a pivot operation, yielding a trajectory which ...

Modeling Relative Trajectory Costs for Airborne Trajectory Reroutes using Trajectory Option Sets

2021 IEEE/AIAA 40th Digital Avionics Systems Conference (DASC), 2021
This paper proposes a novel approach to calculating Relative Trajectory Costs (RTC) as part of a new third-party tool to enable advanced airborne reroute operations. A selection of cost and delay factors, such as Crew, Fuel, Airspace Cost and Downstream Congestion, have been modeled to rank reroute options within the NextGen capability called the ...

Enumeration of complete set of flock patterns in trajectories

Proceedings of the 5th ACM SIGSPATIAL International Workshop on GeoStreaming, 2014
In this paper, we consider the problem of mining the complete set of spatio-temporal patterns, called maximal-duration flock patterns (Gudmundsson and van Kreveld, Proc. ACM GIS 2006) from massive mobile GPS location streams. Such algorithms are useful for mining and analysis of real-time geographic streams in geographic information systems. Although a

Limit Sets of Trajectories

1991
Dynamical polysystems defined on closed manifolds and consisting of finite number of smooth vector fields are considered. ω-limit sets of their trajectories are studied. If a polysystem consists of one vector field we have an old and difficult problem in the Qualitative Theory of differential equations.
