The technique allows a secret image to be divided as n image shares so that: i) any k image shares (klesn) can be used to reconstruct the secret image in lossless manner and ii) any (k-1) or fewer image shares cannot get sufficient information to reveal the secret image. It is an effective, reliable and secure method to prevent the secret image from being lost, stolen or corrupted. In comparison with other image secret sharing methods, this approach's advantages are its large compression rate on the size of the image shares, its strong protection of the secret image and its ability for realtime processing","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"97 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":"117199110","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 problems are related to the POMDP family. In this case however, we are manipulating continuous-valued controls and continuous-valued decisions. While the dynamical programming method will rely on a discretization of the problem, we are dealing here directly with the continuous data. Moreover, our purpose is to address the full past observation range. Our approach is to modelize the POMDP strategies by means of dynamic Bayesian networks. A method, based on the cross-entropy is implemented for optimizing the parameters of such DBN, relatively to the POMDP problem. In this particular work, the dynamic Bayesian networks are built from semi-continuous probabilistic laws, so as to ensure the manipulation of continuous data","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"41 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120999558","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}

Each sensor reports the time when a target crosses the sensor's coverage area sensors may also report features associated with the target.

While much of the current research is involved with evaluating fusion systems based on the quality of their outputs, this paper describes the expansion of this scope to include the complexity of the inputs. Since the quality of the outputs is highly dependent on the difficulty of the input scenario, the methodology described in this paper provides us with a more well-rounded interpretation of fusion system performance. Moreover, characterization and quantification of input scenarios allows for the creation and variation of test scenarios, leading to more efficient optimization of fusion systems. A series of complexity and performance metrics were designed according to a common standard to measure the various aspects of the input scenario and the fusion system solution. Finally, these metrics are combined to obtain an assessment index which provides a description of the fusion system performance","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"31 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":"125000718","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}

Real-time systems are unable to process all of the imagery, demanding some method for prioritization of the processing resources. Furthermore, various segmentation algorithms exist within image processing, each algorithm possesses unique capabilities, and each algorithm has an associated computational cost. Additional complexity arises in the prioritization problem when targets become occluded (i.e., a building) and when the targets are intermixed with other dismounted entities. This added complexity leads to the question \"which portions of the scene warrant both low cost and high cost processing?\" The approach presented in this paper is to apply multi-target tracking techniques in conjunction with an integer programming optimization routine to determine optimal allocation of the video processing resources. This architecture results in feedback from the tracking routine to the image processing function which in turn enhances the ability of the tracker","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"52 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":"122107407","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}

Hence, an approximation of the true density is required. Instead of using a single complicated approximating density, this paper is concerned with bounding the true density from below and from above by means of two simple densities. This provides a kind of guaranteed estimator with respect to the underlying true density, which requires a mechanism for ordering densities. Here, a partial ordering with respect to the cumulative distributions is employed. Based on this partial ordering, a modified Bayesian filter step is proposed, which recursively propagates lower and upper density bounds. A specific implementation for piecewise linear densities with finite support is used for demonstrating the performance of the new approach in simulations","PeriodicalId":248061,"journal":{"name":"2006 9th International Conference on Information Fusion","volume":"45 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":"129609006","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}
