Minimal sensor integrity in sensor grids
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 959-964 vol.2 - 2002
We define the problem of maximal sensor integrity placement, that of locating sensors in n-dimensional grids with minimal vulnerability to enemy attack or sensor faults. We show a polynomial time algorithm for computing sensor integrity exists for sensors with unbounded ranges deployed over a 1D grid of points. We then present an integer linear programming (ILP) formulation for computing sensor in...... hiện toàn bộ

Information fusion in a cooperative multi-agent system for web information retrieval
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 1256-1262 vol.2
As an attempt to solve some contemporary web information retrieval problems, a construction of a cooperative multiagent system is proposed. This. paper introduces the system and presents the use of a, unique aggregation and fusion technique that is employed to attain reliable delivery performance. The intelligent methodology to fuse agents' decisions, the team consensus approach, models the intera...... hiện toàn bộ

Improved joint probabilistic data association algorithm
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 1602-1604 vol.2
The joint probabilistic data association (JPDA) filter has a very good tracking performance in dense targets and heavy clutter environments. However, the JPDA filter also has a huge computer load and tends to combine neighboring tracks. In this paper, an improved JPDA algorithm is presented. The main feature of our method is improving the performance of the JPDA algorithm by improving the performa...... hiện toàn bộ

Inverse pignistic probability transforms
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 763-768 vol.2
In some information fusion processes, the incomplete information set can be naturally mapped into a belief theory information set and a Bayesian probability theory information set. For decision making, the mapping of the belief theory fusion results represented by the basic belief assignment to a probability set is accomplished via a pignistic probability transform. This article introduces the inv...... hiện toàn bộ

Information fusion for image analysis: geospatial foundations for higher-level fusion
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - 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...... hiện toàn bộ

Littoral tracking using particle filter
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 935-942 vol.2
Littoral tracking refers to the tracking of targets on land and in sea near the boundary of the two regions. A ground-moving target continues to move on land and can not enter the sea. Similarly, a sea-moving target moves in the sea and the land serves as an infeasible region. Enforcing infeasible regions or hard constraints in the framework of the Kalman filter or interacting multiple model (IMM)...... hiện toàn bộ

Exploitation of Landsat imagery and ancillary data for battlespace characterization
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 994-998 vol.2
Spectral data provide opportunities to discriminate targets from background clutter and to detect partially concealed objects. However, data with high spatial resolution generally are not synoptic scale (hundreds of kilometers). By analyzing courser resolution synoptic imagery, high-resolution sensors can then be cued to areas of potential targets. Multispectral images (Landsat 7) are combined wit...... hiện toàn bộ

Fusion of multi-modality volumetric medical imagery
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 1206-1212 vol.2
Ongoing efforts at our laboratory have targeted the development of techniques for fusing medical imagery of various modalities (i.e. MRI, CT, PET, SPECT, etc.) into single image products. Past results have demonstrated the potential for user performance improvements and workload reduction. While these are positive results, a need exists to address the three-dimensional nature of most medical image...... hiện toàn bộ

An improved Bayes fusion algorithm with the Parzen window method
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 1 - Trang 651-657 vol.1
In this paper, a new Bayes fusion algorithm with the Parzen window method, which introduces the non-parameter estimation method of partition recognition into traditional Bayes fusion criterion, is propose. During the process of fusion, which is a repetitious and iterative process, conditional probability density is continuously modified and learned using the Parzen window method, and the global de...... hiện toàn bộ

Creating knowledge from heterogeneous data stove pipes
Proceedings of the Fifth International Conference on Information Fusion. FUSION 2002. (IEEE Cat.No.02EX5997) - Tập 2 - Trang 1162-1167 vol.2
The modern day challenges posed by terrorism and crime mean that we must make better use of the data we collect. We need to create a process that can transform different types of explicit and structured data into actionable knowledge. We need to be able to create unified infrastructure that will support a single query across all of the data sources. This unified infrastructure would allow us to in...... hiện toàn bộ
