As a novel multiscale geometric analysis tool, Contourlet has shown many advantages over the conventional image representation methods. It provides flexible number of directions and captures the intrinsic geometrical structure of images. The efficient directional filter banks with low redundancy of contourlet are very attractive for image processing. Experiments show the proposed image fusion method can have better performance than existing image fusion methods,which is good for further image Processing and Analysis such as identical micro surface target recognition, impurity feature extraction and etc","PeriodicalId":153560,"journal":{"name":"2009 International Symposium on Intelligent Ubiquitous Computing and Education","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128417239","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}

Unfortunately, NATs block the data transmitted directly between two Nodes under different private networks in many peer-to-peer applications. A protocol, STUN (Simple Traversal of UDP over NATs), has been proposed by IETF to solve the problem, but it costs great network bandwidth and transmission delays when the number of Nodes is large. In addition, it is less flexible between different network conditions. To solve this problem, this paper makes many practices to improve STUN and proposes a novel NAT traversal technology to establish peer-to-peer connections, enabling load on the sever to be remarkably reduced.  Our algorithm called C_STUN classifies Node’s area and select proper traversal method dynamically, which can   accelerate Nodes’ connection in a large and complicated peer-to-peer network.","PeriodicalId":153560,"journal":{"name":"2009 International Symposium on Intelligent Ubiquitous Computing and Education","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130519805","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 scheme is also based on incentive values to make better cooperation.
