When the bearing measurements from each sensor have been associated to form sequences termed threads, the problem is to associate pairs of threads to identify the true target intersections. In this paper we present two algorithms: (i) classical bayesian thread association (CBTA) and (ii) Monte Carlo thread association (MCTA), for this problem. The performance of these algorithms is compared using Monte Carlo simulations. Furthermore, we also compare their performance against the Rao-Blackwellised Monte Carlo Data Association (RBMCDA) algorithm, which uses unthreaded measurements, in order to ascertain the benefits of using thread information. Simulations show that MCTA is superior to CBTA, and that there is significant benefit in using thread information in this class of problems.","PeriodicalId":298941,"journal":{"name":"2007 10th International Conference on Information Fusion","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123992053","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}

These tools should take advantage of the human cognitive ability to fuse and assimilate multiple sources and types of information; image fusion tools should be judged successful if they trigger new insight for the Image Analyst. This paper describes some relatively- simple methods for the exploitation of synthetic aperture radar (SAR) and electro-optical (EO) commercial satellite imagery, with a focus on their integration into the geospatial intelligence workflow. Two examples of multi-temporal satellite imagery products produced by a DRDC Ottawa test-bed system, Image Analyst Pro, are presented.

The typical maneuvering models, as described, essentially, are prior models and use fixed and constant evolved matrix and designed noise level for whole filtering procedure. Actually, the motion of target is always too complicated to be prior modeled as a fixed form, meanwhile, Q used to reflect the mis-match error between the mathematic model and the actual maneuvering mode, thus is time-varying and severely influenced by the environment around the target. Therefore, the prior f and Q can not characterize the maneuvering mode exactly, hence, by assumption that the state evolution and the likelihood of measurements data can be represented by Gaussian distribution, the method of identifying f and Q online is developed. Comparing with the standard IMM filtering, Monte Carlo simulations show that the proposed algorithm is efficient and filtering precision can be improved to some extent.","PeriodicalId":298941,"journal":{"name":"2007 10th International Conference on Information Fusion","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125021879","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 the belief functions theory one of the major problem is the conflict repartition enlightened by the famous Zadeh's example. To date, many combination rules have been proposed in order to solve a solution to this problem. Moreover, it can be important to consider the specificity of the responses of the experts. Since few year some unification rules are proposed. We have shown in our previous works the interest of the proportional conflict redistribution rule. We propose here a mixed combination rule following the proportional conflict redistribution rule modified by a discounting procedure. This rule generalizes many combination rules.","PeriodicalId":298941,"journal":{"name":"2007 10th International Conference on Information Fusion","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128701382","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}

These images contain a large number of contiguous bands to provide information at a fine spectral resolution and, therefore, cannot be displayed directly using an RGB color display. There has been some recent work on the problem of fusing hyperspectral images to three-band images for color display purposes. In this paper, we evaluate the performance of our recently proposed approach based on independent component analysis, correlation coefficient and mutual information (ICA- CCMI) to fuse the information from a large number of bands to three images suitable for color display. Depending on whether the reference images are available or not, several image quality metrics such as entropy and edge correlation have been proposed and employed to evaluate the fusion performance via three widely used hyperspectral image datasets.","PeriodicalId":298941,"journal":{"name":"2007 10th International Conference on Information Fusion","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128749380","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}

An interesting approach was developed for the decision- level identity fusion, which use optimization techniques to minimize an objective function which measure the dissimilarities between the combination result and the set of initial sensor reports. Several objective functions were already proposed for the similar sensor fusion (SSF) and the dissimilar sensor fusion (DSF) models.
