Information fusion for image analysis: geospatial foundations for higher-level fusion
Tập 1 - Trang 562-569 vol.1
In support of the AFOSR program in Information Fusion, the CNS Technology Laboratory at Boston University is developing and applying neural models of image and signal processing, pattern learning and recognition, associative learning dynamics, and 3D visualization, to the domain of Information Fusion for Image Analysis in a geospatial context. Our research is focused by a challenge problem involvi......

A new method for representing linguistic quantifications by random sets with applications to tracking and data fusion
Tập 2 - Trang 1308-1315 vol.2
There is an obvious need to be able to integrate both linguistic-based and stochastic-based input information in data fusion. In particular, this need is critical in addressing problems of track association, including cyber-state intrusions. This paper treats this issue through a new insight into how three apparently distinct mathematical tools can be combined: "boolean relational event algebra" (......

General tracking performance description for systems of sensors
Tập 1 - Trang 128-134 vol.1
Traditionally, radar or sensor performance is reviewed in terms of detection ranges and measurement accuracy. Today, when the radar often is a part of a locally integrated sensor system, which shall cooperate with other sensor systems, other performance parameters are required for evaluation and comparison of various solutions. The present paper gives an analysis method for descriptions of the tra......

Dependence in network reliability
Tập 2 - Trang 981-985 vol.2
It is fairly easy to calculate the reliability of a network with independent nodes by using a technique called pivoting. However, when there is dependence, this calculation will prove inaccurate and a model for the dependence is required. This paper considers the issues involved in developing a suitable model. Particular emphasis is placed on ensuring the calculations and distributions involved do......

Ballistic track initialization from a bisatellite surveillance imaging system
Tập 2 - Trang 1015-1022 vol.2
This paper presents a new approach for ballistic target detection and tracking based on delocalized bisatellite surveillance system. The basic idea for track initialization is to use the advantage of stereovision provided by the two imaging IR sensors aboard surveillance geostationary satellites to improve the quality of true target track detection and to reduce the number of false track initializ......

Active information fusion for decision making under uncertainty
Tập 1 - Trang 643-650 vol.1
Many information fusion applications especially in military domains are often characterized as a high degree of complexity due to three challenges: 1) data are often acquired from sensors of different modalities and with different degrees of uncertainty; 2) decision must be made quickly; and 3) the world situation as well as sensory observations evolve over time. In this paper, we propose a dynami......

Information fusion technology requirements for the National System for Geospatial Intelligence (NSGI) enterprise
Tập 2 - Trang 784-791 vol.2
The future success of the National Imagery and Mapping Agency (NIMA) and the National System for Geospatial Intelligence (NSGI) will hinge on the agency's ability to deliver timely, tailored, precise data, information and knowledge to its customers. NIMA must understand what information truly matters and foster an analytical environment that encourages creativity and excellence. Achieving this vis......

Track-to-track fusion of out-of-sequence tracks
Tập 2 - Trang 919-926 vol.2
Fusing out-of-sequence information is a problem of growing importance due to an increased reliance on networked sensors embedded in complicated network architectures. The problem of fusing out-of-sequence measurements (OOSM) has received some attention in literature; however, most practical fusion systems, owing to compatibility with legacy sensors and limited communication bandwidth, send track i......

Optimal linear unbiased filtering with polar measurements for target tracking
Tập 2 - Trang 1527-1534 vol.2
In tracking applications, target dynamics is usually modeled in the Cartesian coordinates, while target measurements are directly available in the original sensor coordinates. Measurement conversion is widely used such that the Kalman filter in the Cartesian coordinates can be applied. A number of improved measurement-conversion techniques have been proposed recently. However, they have fundamenta......

An information theoretic justification for covariance intersection and its generalization
Tập 1 - Trang 505-511 vol.1
A technique for fusing Kalman filter information has been developed by Jeffrey Uhlmann, Simon Julier, and their associates that addresses the problems that arise from fusing correlated measurements. The researchers have named this technique "covariance intersection" and have presented papers on it at several robotics and control theory conferences. The technique is applicable to these research are......
