Results show that this approach is generally suitable for most of the images; and performs even better on images with darker background.","PeriodicalId":164945,"journal":{"name":"2012 International Conference on Systems and Informatics (ICSAI2012)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128145153","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}

Based on analysis of the classic algorithm of eliminating the duplicates, his article raises an improved algorithm for judging web page text repetition. The new algorithm runs the elimination process on the basis of webpage contents which are used as the vector characteristics in the comparison with the webpages' approximation, and analyzes how to capture the web page's theme. Hence, we can make a multidimensional improvement in the elimination of the duplicates of multimedia webpages.","PeriodicalId":164945,"journal":{"name":"2012 International Conference on Systems and Informatics (ICSAI2012)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133760537","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}

The proposed scheme introduced a significant diffusion effect through a two-stage diffusion algorithm. In first-diffusion stage, we turn each pixel of the original image into 8 bits binary sequence, and apply Chebyshev map to shuffle the 8 bits binary sequence. In second-diffusion stage, we apply quadratic residue to encrypt the new binary sequence. Therefore, the proposed scheme transforms the statistical characteristics of plain image information drastically and randomly. Finally, Various types of security analyses demonstrate that the security of the proposed scheme is competitive with that of permutation-diffusion type image cipher and is very proper for realtime secure image communication applications.","PeriodicalId":164945,"journal":{"name":"2012 International Conference on Systems and Informatics (ICSAI2012)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131847075","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 mismatch leads to time-consuming work for designers when saving and storing objects in relational databases. To solve the problem, this paper put forward data class object container method. This object container encapsulates direct access to the database in a base class and provides generic interface services. Objects derive from this base class to form specific data classes, and therefore, the data class container is created. By this means, the coupling between object models and the relational database can be greatly reduced.","PeriodicalId":164945,"journal":{"name":"2012 International Conference on Systems and Informatics (ICSAI2012)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125258963","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}

The function of parallel computation in Open Multi-Processing is introduced to accelerate calculation on multi-core computers.
