Multi-scale Classification of Moving Objects Trajectories

Abstract

In this paper we propose a classification model formoving objects trajectories.We assume that the classificationis based on a multi-scale map, and we simplydefine a trajectory pattern as the sequence of zones anobject crosses during its travel.These patterns constitutethe basis of classification operators.We also definea pattern-based query language which allows an onlineand continuous classification of moving objects.Finallya prototype which shows the validity of the approach isbriefly described.
