We propose in this chapter a content-based informationretrieval framework to select documents in a database, consisting ofseveral images with semantic information. Information in these doc-uments is not only heterogeneous, but also often incomplete. So,themethod we propose may cover a wide range of applications. To se-lect the most relevant cases in the database, for a query...

This document describes what particular pieces of information about source should be taken into account to get a reasonable assessment of an attribute information retrieved based on the sensor data or human originated information. It has been proven that actual sensor weights and hypotheses masses do not change randomly, but they vary in time according to tracked target motion, however not dire...

This chapter presents comparative results of a model for multiple cameras fusion, which is based on Dezert-Smarandache theory of evidence. Our architecture works at the decision level to track objects on a ground plane using predefined zones, producing useful information for surveillance tasks such as behavior recognition. Decisions from cameras are generated by applying a perspective-based bas...

Today due to the importance and necessity of implementing security systems in homes and other buildings, systems with higher certainty, lower cost and with sensor fusion methods are more attractive, as an applicable and high performance methods for the researchers. In this paper, the application of Dempster-Shafer evidential theory and also the newer, more general one Dezert-Smarandache theory ...

In situation analysis (SA), an agent observing a scene receives information from heterogeneous sources of information including for example remote sensing devices, human reports and databases. The aim of this agent is to reach a certain level of awareness of the situation in order to make decisions. For the purpose of applications, this state of awareness can be conceived as a state of knowledg...

Multi-target tracking system is used to distinguish the class from different targets and obtain the trajectory of all targets from multiple information systems. As a significant and novel information fusion method, evidence theory has been used in multi-target tracking system. The evidence combination rule which is the core of evidence theory is turning into a new research emphasis. Yager combi...

The objective of this chapter is to present and compare different fusion rules which can be used for Generalized Data Association (GDA) for multitarget tracking (MTT) in clutter. Most of tracking methods including Target Identification (ID) or attribute information are based on classical tracking algorithms such PDAF, JPDAF, MHT, IMM, etc. and either on the Bayesian estimation and prediction of...

Since the development of belief function theory introduced by Shafer in seventies, many combination rules have been proposed in the literature to combine belief functions specially (but not only) in high conflicting situations because the emblematic Dempster’s rule generates counter-intuitive and unacceptable results in practical applications. Many attempts have been done during last thirty yea...
