The collection, visualization, and analysis of movement data is at the forefront of geographic
information science research. Movement data are generally collected by recording an …

The proliferation of trajectory data in various application domains has inspired tremendous
research efforts to analyze large-scale trajectory data from a variety of aspects. A …

The rapid development and increasing availability of various location acquisition
technologies provide geospatial studies with both opportunities and challenges. These …

Temporal data mining deals with the harvesting of useful information from temporal data.
New initiatives in health care and business organizations have increased the importance of …

In this paper, we attempt to approximate and index a d-dimensional (d≥ 1) spatio-temporal
trajectory with a low order continuous polynomial. There are many possible ways to choose …

Nearest neighbor search and many other numerical data analysis tools most often rely on
the use of the euclidean distance. When data are high dimensional, however, the euclidean …

We propose a segmentation and feature extraction method for trajectories of moving objects.
The methodology consists of three stages: trajectory data preparation; global descriptors …

This paper proposes a novel method for detecting nonconforming trajectories of objects as
they pass through a scene. Existing methods mostly use spatial features to solve this …

This article describes a novel approach for finding similar trajectories, using trajectory
segmentation based on movement parameters (MPs) such as speed, acceleration, or …

Trajectory database (TD) management is a relatively new topic of database research, which
has emerged due to the explosion of mobile devices and positioning technologies …
