Tracking represents a set  of techniques that, fusing information from various sensors, aims at identifying and predicting  objects'  motion. 

 

Tracking Moving Objects in Image Sequences

The task of extracting information about objects' motions from image frames gathered on complex unstructured scenes is addressed in our work,  We use  a combination of pattern recognition  and tracking techniques. Performance evaluation is difficult because of the high variability present in real sequences. We focus on a detailed analysis of quality parameters by comparing the results of the algorithms with labelled "ground truth" sequences.

Resolution Analysis for Closely-Spaced Objects

 

We analyze a model of a pixel-based sensor in its capability of resolving objects at sub-pixel accuracy.

Target Tracking Over the Horizon

Tracking targets  located in the far distance suffers from the presence of large number of false alarms. We analyze the perfarmance of a PMHT tracker in such a scenario.

Use of Ellipsoidal Regions for Conflict Detection

 When agents, such as vessels or vehicles, move in a given space, they have to keep track of the other agents to avoid collisions. The process may be computationally intensive if large number of agents are present on the scene. Ellipsoidal regions are considered as safety regions as they require a small number of parameters.

Target Tracking from Multiple Cameras

When multiple cameras look over a scene, they have to use prospective analysis to convert image data to spatial positions. Il this work we fuse information from multiple cameras in a Factor Graph-based tracker.
