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" (...

Dynamic I/O power management in real-time systems with multiple-state I/O devices
Tập 2 - Trang 1588-1595 vol.2
Power consumption is now an important design parameter for distributed sensor
networks. While dynamic (or software-controlled) power management (DPM) is being
increasingly used as an alternative to inflexible hardware solutions, DPM for
hard real-time systems has received relatively little attention. In particular,
energy-driven I/O device scheduling for real-time systems has received even less
at...

Model-set design for multiple-model method. II. Examples
Tập 2 - Trang 1347-1354 vol.2
This paper presents several examples that illustrate how the theoretical results
presented in part I and other work can be applied, along with a demonstration of
their effectiveness, in the context of MM estimation for air traffic control
surveillance. Model-set design and choice examples are presented. The importance
and usefulness of modeling true mode and models as random variables are
demonstr...

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...

Coalitions for distributed sensor fusion
Tập 1 - Trang 636-642 vol.1
We address the problem of efficient use of communication bandwidth in a network
of distributed sensors. Each sensor node has enough computational power to fuse
its own estimates with those of other nodes using an optimal filter, but message
passing is expensive. The goal is to give each node an identical tactical
picture of the area of interest without compromising target track accuracy. In
the cu...

Plenary speech III: visual appearance modeling and perception with retinal and cortical signal processing
Tập 2 - Trang 900 vol.2
Summary form only given. This talk focuses on the problem of shape estimation
using multiple views from a land based mobile robot equipped with CCD cameras
and a laser range finder that can compute the range of a target along a fixed
horizontal plane. The talk surveys the problem of shape estimation from optical
flow of points, lines and algebraic curves and emphasizes the fusion of camera
and ran...

Evolving feature extraction algorithms for hyperspectral and fused imagery
Tập 2 - Trang 986-993 vol.2
Hyperspectral imagery with moderate spatial resolution (/spl sim/30 m) presents
an interesting challenge to feature extraction algorithm developers, as both
spatial and spectral signatures may be required to identify the feature of
interest. We describe a genetic programming software system, called GENIE, which
augments the human scientist/analyst by evolving customized spatio-spectral
feature ext...

Multi-entity Bayesian networks for situation assessment
Tập 2 - Trang 804-811 vol.2
Reasoning about military situations requires a scientifically sound and
computationally robust uncertainty calculus, a supporting inference engine that
procedurally encodes the axioms of the calculus, the capability to fuse
information at multiple levels of abstraction, and the ability to respond to
dynamic situations. The inference engine also needs to be able to encapsulate
expert knowledge, inc...

Tactical ballistic missile tracking using the interacting multiple model algorithm
Tập 2 - Trang 824-831 vol.2
The problem of tracking a tactical ballistic missile is complicated by the
varying target dynamics in the boost, exo-atmospheric and endo-atmospheric
phases of flight. A single Kalman filter tuned for constant velocity or constant
acceleration is not based upon the correct underlying physical model of these
dynamics. By including models with all of the correct dynamics, an interacting
multiple mod...
