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" (...

High performance real-time fusion architecture
Tập 2 - Trang 1478-1485 vol.2
There currently exists the need for fusion systems that can provide an accurate
and comprehensive assessment of military situations in real-time. The objective
of this effort was to define, prototype, and demonstrate an affordable
next-generation JDL Level 2 fusion and exploitation architecture. The scope of
this effort included the identification of the limiting criteria in current
Level 2 fusion...

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...

Multicomponent signal classification using the PMHT algorithm
Tập 1 - Trang 751-757 vol.1
The probabilistic multi-hypothesis tracking (PMHT) algorithm is extended for
application to classification. The PMHT model is reformulated as a bank of
continuous-state hidden Markov models, allowing for supervised learning of the
class-conditional probability density models, and for likelihood evaluation of
multicomponent signals.

Comparison of plot and track fusion for naval sensor integration
Tập 2 - Trang 1361-1366 vol.2
This paper compares plot and track fusion or a generic suite of sensors that
might be available on a future warship, with an emphasis on their relative
ability to maintain track continuity in the event of missed measurements/plots.
Using plot fusion measurement level data are formed into tracks at a central
location, whereas with track fusion state estimate (i.e. track) level data are
combined fro...

Tracking in decentralised air-ground sensing networks
Tập 1 - Trang 616-623 vol.1
This paper describes the theoretical and practical development of a
decentralised air and ground sensing network for target tracking and
identification. The theoretical methods employed for studying decentralised data
fusion problems are based on the information-filter formulation of the Kalman
filter algorithm and on information-theoretic methods derived from the Bayes
theorem. The paper particul...

"A multi-resolution outdoor dual camera system for robust video-event metadata extraction"
Tập 2 - Trang 1184-1189 vol.2
This paper describes a cooperative distributed system for outdoor surveillance
based on fixed and mobile cameras. In order to continuously monitor the entire
scene, a fixed unidirectional sensor has been used, mounted on the roof of a
building in front of the guarded area. To obtain higher resolution images of a
particular region in the scene, an active pan-tilt-zoom camera has been used.
The low ...

Situation assessment via Bayesian belief networks
Tập 1 - Trang 664-671 vol.1
We present here an approach to battlefield situation assessment based on a level
2 fusion processing of incoming information via probabilistic Bayesian Belief
Network technology. A belief network (BN) can be thought of as a graphical
program script representing causal relationships among various battlefield
concepts represented as nodes to which observed significant events are posted as
evidence. ...

An anatomofunctional brain knowledge
Tập 2 - Trang 1269-1276 vol.2
This study proposes the elaboration of a fusion model into two kinds of data for
patients presenting sequelae of focal brain damage : anatomical and functional.
The aim of our model is to merge these two kinds of information to help
diagnosis and to contribute to the comprehension of the neural basis of
cognitive functions. On one hand, interrelationships between anatomic elements
constitute an an...
