The LWIR mode mediated the detection of camouflaged thermal targets but did not allow the detection of visual targets, and provided insufficient detail to allow accurate movement through the environment Subjects were quite capable to dichoptically fuse the individual LWIR and NVG images, enabling them to detect all (visual and thermal) targets while moving accurately through the environment We conclude that dichoptic fusion of NVG and LWIR imagery is quite feasible and is a simple way to provide observers with enhanced situational awareness in nighttime operations","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123611419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, we consider that the color quantization problem can be viewed as clustering problem of the color-space into P clusters. Using TBM, we define a top-down evidential clustering algorithm which iteratively decreases the number of clusters of the color space into P clusters. This convergence is ensured using a novel criterion based upon the pignistic probability function. The P clusters provide the new reduced color palette and a quantized color image is computed. This quantization method is completely automatic and preserves the final result from any initial condition.

The resource management problem of today's US military is perhaps the largest and most complex optimization problem in terms of the number of variables representing various resource types and constraints relating the variables. This modern resource management problem needs to be considered within a network centric warfare (NCW) environment, and hence the term \"sense and respond logistics\" (S&RL). In this article, the author views the resource management issue as intimately related to the problem of planning and scheduling of tasks, that is, one cannot effectively reason with resources in isolation. In the data fusion domain, this view translates to consideration of the collection management process during situation/threat assessment and courses-of-action generation processes. Within a NCW environment a node must proactively determine mission requirements based on the current situation and threat, and then coordinate with other nodes to meet those requirements via some communication mechanism (e.g. publish and subscribe) on the underlying infrastructure. The specific algorithmic approach the author advocates for dynamically managing resources is essentially based on constraint programming (CP) techniques, where constraints are declaratively stated and placed on the types and quantities of resources at hand. The constraints can also be dynamically added or retracted from the system, thus are suitable to meet the demands of a dynamic resource management environment. The approach distinguishes between consumable and non-consumable resources, and in some situations views time as a special kind of resource. The author illustrates the CP approach to resource management in NCW environments in terms of two examples. The first example is related to surveillance asset management and the second is related to logistics","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129629244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has several advantages for multi-agent systems using BDI agents. First, because of the use of event correlation and data fusion techniques in situation management, agent platforms can support highly reactive distributed applications. Second, the situation manager provides a semantically rich representation of the world and can dynamically adapt its representation for situations over time. From the system architecture perspective, we discuss several alternatives for how existing BDI-capable agent platforms can incorporate this extension. These alternatives range from complete SM functionality in each agent to having shared SM functionality among multiple agents. We also consider environments where different agent platforms use our situation-based BDI (SBBDI) agent method and must interoperate.

The paper describes the different modes and the relevant attainable performances of the developed tracking algorithm. The adopted data fusion technique for tracking is the Kalman filter.
