The method is based on two main ideas. The first one consists to model the image as grid of the virtual electric potential and to exploit the corners detected by an improved version of Harris and Stephens detector. Characteristic of gradient vectors at the corners detected is used in order to draw the strait lines. The second one uses the invariance property of the correlation matrix eigenstructure decomposition. The correlation matrix is formulated from the directing vectors of the straight lines. To determine the correspondence between the lines and to remove the outliers we use an affinity function based on a heuristic criterion. The performances of the method are degraded considerably in presence of noise. For this reason, a preprocessing stage is suitable. It consists to estimate the noise correlation matrix by evaluating iteratively the noise subspace in order to improve the signal noise ratio (SNR). The robustness of the method to the noise and the outliers is remarkable in synthetic or real images.","PeriodicalId":314768,"journal":{"name":"2007 International Symposium on Computational Intelligence and Intelligent Informatics","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131384286","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}

For a given network with two possible transmission powers (low and high), the problem is to find a minimum size subset of nodes such that if they are assigned high transmission power while the others are assigned low transmission power, the network will remain strongly connected. The main purpose behind this efficient setting is to minimize the total communication power consumption while maintaining the network connectivity. In a theoretical point of view, the problem is known to be difficult to solve exactly. An approach to approximate the solution is to work with a spanning tree of clusters. Each cluster is a strongly connected component when consider low transmission power. We follow the same approach, and we formulate the node selection problem inside clusters as an integer programming problem which is solved exactly using specialized codes. We refine our algorithm by exploring different spanning trees following a breath-first exploration procedure. Experimental results show that our algorithm is efficient regarding the execution time as well as the quality of the solution.","PeriodicalId":314768,"journal":{"name":"2007 International Symposium on Computational Intelligence and Intelligent Informatics","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133201254","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}

To help the decision makers in the territory management, several actors have shown the adequacy of the association of the geographical information systems (GIS) and the multicriterion decision aid (MCDA) methods. This association not only permits to manage the spatial reference information but also to apply new analysis methods permitting to have the most pertinent and most profitable information. However, most problems of MCDA take into account not only the traditional quantitative criteria, but also the qualitative and imprecise criteria, which make their use difficult for the decision and analysis. We propose in this paper, a hybrid model of MCDA for the localization of a site for the implantation of a chemical products factory. This model enables us to combine the use of the multi-representation geographical information systems (MRGIS) and the MCDA methods, such as AHP (analytic hierarchy process). Then, to facilitate the interpretation of the qualitative data in our model, we propose an approach of data modelling based on the fuzzy set theory, which makes it possible to interpret the qualitative values by precise values rather than by classical intervals.","PeriodicalId":314768,"journal":{"name":"2007 International Symposium on Computational Intelligence and Intelligent Informatics","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126327516","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}
