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" (...

Neural networks estimation of truck static weights by fusing weight-in-motion data
Tập 1 - Trang 456-462 vol.1
This paper presents a complete neural networks approach developed to improve the
accuracy of multiple-sensor Weigh-In-Motion system. This system consists in
fusing the dynamical measurements of individual sensors installed in the road,
into one improved estimate of static gross or axle weight. This task is complex
due to the difficulty to inverse the model that describes the dynamical
vehicle-pave...

Fusion under unknown correlation - covariance intersection as a special case
Tập 2 - Trang 905-912 vol.2
This paper addresses the problem of fusing several random variables (RVs) with
unknown correlations. A family of upper bounds on the resulting covariance
matrix is given, and is shown to contain the upper bound offered by the
covariance intersection (CI) algorithm proposed by Julier and Uhlmann (2000).
For trace minimization, the optimal one in this family is better than the one
obtained by CI exc...

An integrated method to detection, data association and tracking of multiple broadband signals
Tập 1 - Trang 727-734 vol.1
The present work explores a new method of integrated detection, localization,
and tracking of multiple broadband signals directly from array data, without the
requirement of distinct data association. The method is based on Maximum
A-Posteriori probability concepts and combines Maximum Likelihood direction
finding techniques with Kalman Filter theory. Implicit data association is given
by a Nonlin...

Sensor validation and fusion using the Nadaraya-Watson statistical estimator
Tập 1 - Trang 321-326 vol.1
The paper describes a novel integrated sensor validation and fusion scheme based
on the Nadaraya-Watson statistical estimator. The basis of the sensor validation
scheme is that observations used to implement the estimator are obtained from
valid sensor readings. Pattern matching techniques are used to relate a
measurement vector that is not consistent with the training data to the closest
a-priori...

Scalable data fusion using Astrolabe
Tập 2 - Trang 1434-1441 vol.2
The dramatic growth of computer networks creates both an opportunity and a
daunting distributed computing problem for users seeking to perform data fusion
and data mining. The problem is that data often resides on large numbers of
devices and evolves rapidly. Systems that collect data at a single location
scale poorly and suffer from single-point-failures. Astrolabe performs data
fusion in real-ti...

Performance results of recognizing various class types using classifier decision fusion
Tập 1 - Trang 266-271 vol.1
Classification performance is compared using data based on waveforms that are
transmitted at both low and high frequencies. The waveforms are made up of one
low, and one high, bandwidth type. Various features have been extracted from
each waveform for training different classifiers. Specifically, the classifier
types consist of various neural networks, Weighted voting (Linear), Fisher's
Linear dis...

Interferometric image fusion: interferometry in space
Tập 2 - Trang 1221-1227 vol.2
Image fusion and information extraction from multiple spacecraft can occur after
each image is sampled and digitized. A more tantalizing, but difficult, approach
would be to optically phase multiple spacecraft flying in formation. Phasing of
multiple spacecraft allows for coherent addition of imagery resulting in an
optical system with a synthetic aperture as large as distance between the
spacecra...

Synchronized GMTI radar collection management in a coalition environment
Tập 2 - Trang 1046-1053 vol.2
Surveillance of ground targets from airborne systems is increasingly of interest
in tactical operations. Collection management synchronization can provide
improved tactical data products for multi-platform operations. Synchronization
of collection management is considered for coalition operations involving
multiple airborne GMTI radar systems. An emerging synchronization collection
management plan...
