The proposed technique presents an advance multiband satellite colour, contrast improvement technique of a poor-contrast satellite images. The input image is decomposed into the two frequency sub bands by using DCT and estimates the singular value matrix of the lowâ\"low sub band image and then it reconstructs the enhanced image by applying inverse DCT. This technique is useful for the betterment of the INSAT as well as LANDSAT satellite image for the feature extraction purpose. The singular value matrix represents the intensity information of the given image and any change on the singular values change the intensity of the input image. The proposed technique converts the image into the DCT-SVD domain and after normalizing the singular value matrix, the enhanced image is reconstructed by using IDCT. The visual and quantitative results suggest that the proposed DCT-SVD method clearly shows the increased efficiency and flexibility of the proposed method over the exiting methods such as the Decor relation Stretching, Linear Contrast Stretch, GHE and DWT-SVD based techniques. The experimental results show the superiority of the proposed method over conventional methods.","PeriodicalId":235770,"journal":{"name":"2012 Third International Conference on Computer and Communication Technology","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121395392","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}

Free riding phenomenon was first felt in the study of Gnutella. As the number of free riders increases, the performance of the overall system decreases as free riders use resources without giving anything to the system. To solve the problem of free riding we have developed an Extended Point Based Incentive Mechanism (EPBIM) through which the users are given some incentives to share some files into the system. Our scheme attracts the users to share more and more as it gives more points to the users which provide responses for some queries of other users in the system. This scheme is different from other incentive based schemes in the way that it uses some new parameters for incentives like the time user spends in the network, upload speed of the user, how many simultaneous uploads a user is providing, how many query responses a user is giving and query forwarding of other users in the network. Our simulation results show that this scheme reduces the percentage of free riders to a great extent therefore increasing the performance of a peer-to-peer network.","PeriodicalId":235770,"journal":{"name":"2012 Third International Conference on Computer and Communication Technology","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122613986","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}
