Trajectory Shape Analysis and Anomaly Detection Utilizing Information Theory Tools

Trajectory Shape Analysis and Anomaly Detection Utilizing Information Theory Tools

In this paper, we propose to improve trajectory shape analysis by explicitly considering the speed attribute of trajectory data, and to successfully achieve anomaly detection. The shape of object motion trajectory is modeled using Kernel Density Estimation (KDE), making use of both the angle attribu...
