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" (......

Merger of ocean color information from multiple satellite missions under the NASA SIMBIOS Project Office
Tập 1 - Trang 291-298 vol.1
The purpose of data merger activities undertaken by the Sensor Intercomparison and Merger for Biological and Interdisciplinary Studies (SIMBIOS) Project is to create scientific quality ocean color data sets encompassing measurements from multiple satellite missions. To meet this goal, a number of image processing and data fusion methodologies have been developed within the Project Office. A backpr......

Hợp nhất tạm thời trong hệ thống theo dõi mục tiêu đa cảm biến Dịch bởi AI
Tập 2 - Trang 1030-1037 vol.2
Trong một hệ thống theo dõi đa cảm biến, các ảnh hưởng của các cảm biến lệch thời gian được khảo sát và so sánh với các cảm biến đồng bộ. Để thực hiện các so sánh công bằng, một chỉ số mới, phương sai sai số ước lượng trung bình, được định nghĩa. Nhiều kết quả phân tích được suy ra cho các cảm biến có phương sai tiếng ồn đo được bằng nhau. Các cảm biến lệch thời gian luôn dẫn đến một phương sai sa......

MAP track fusion performance evaluation
Tập 1 - Trang 512-519 vol.1
The purpose of this paper is to develop a quantifiable performance evaluation method for MAP (Maximum A Posterior) track fusion algorithm. The goal is to provide analytical fusion performance without extensive Monte Carlo simulations. The idea is to develop methodologies for steady state fusion performance. Several fusion algorithms such as simple convex combination, cross-covariance combination (......

User based data fusion approaches
Tập 2 - Trang 1457-1462 vol.2
Technology advances in computers, sensors, communications, navigation systems, etc. have lead to significant increases in throughput and capacity of systems. This phenomenon has lead to vast amounts of data residing in C4ISR systems and available to users. In addition that large amounts of data requires updating and taxes communications resources supporting those system. This situation creates a s......

Data fusion architecture for Maritime Surveillance
Tập 1 - Trang 448-455 vol.1
Various multisensor data fusion architectures have been utilized to support the Maritime Surveillance (MS) in maritime tactical and strategic operations. The military tactical situation is mechanized through data fusion thus improving the quality of target tracking system. One of the major problems is that the surveillance area is generally large, hence making it difficult to arrive at a feasible ......

Distributed reinforcement learning for sequential decision making
Tập 2 - Trang 1263-1268 vol.2
The paper addresses a problem of reinforcement learning in a homogeneous non-communicating multi-agent system for sequential decision making. We introduce a particular reinforcement learning model composed of evidential reinforcement neural networks representing agents, a fusion center, and a decision maker. The fusion center combines beliefs in each hypothesis under consideration generated by the......

Structured Knowledge Source Integration and its applications to information fusion
Tập 2 - Trang 1340-1346 vol.2
Structured Knowledge Source Integration, or SKSI, is an ongoing research and development project at Cycorp intended to enable the Cyc knowledge base to integrate (access, query, assimilate, and merge) a variety of external structured knowledge sources, such as databases, spreadsheets, XML or DAML tagged text, GIS datasets, and queryable Web pages. With SKSI, the Cyc knowledge base will be able to ......

Optimal detection in a distributed multisensor architecture
Tập 1 - Trang 34-40 vol.1
A detector defines a subset of inputs for which a detection is declared, as such, the performance of a detector is limited by the input set. The optimal detector which is presented in this paper defines the detection set which provides the maximum probability of detection for a given probability of false alarm. Further improvements in detection performance require a change to the input set. Inclus......
