The main problem in most wrapper induction methods is the difficulty in discriminating the meaningful blocks that contain the target information from the noise blocks that contains irrelevant information such as advertisements, menus, or copyright statements. To solve this problem, this paper proposes the RIPB(recognizing informative page blocks) algorithm that detects the informative blocks in a Web page by exploiting the visual block segmentation scheme. RIPB uses the visual page segmentation algorithm to analyze and partition a Web page into a set of logical blocks, and then groups related blocks with similar structures into a block cluster and recognizes the informative block clusters by applying some heuristic rules to the cluster information. The results of a series of experiments indicate that RIPB contributes to improve the accuracy of information extraction by allowing the wrapper induction module to focus only on the informative block information and ignore other noise information in building extraction rules.","PeriodicalId":394071,"journal":{"name":"2007 International Symposium on Information Technology Convergence (ISITC 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129020257","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 2D-GE images, which represent protein signals as spots of various intensities and sizes, may yield a lot of information that can help the biologists for exploring the elements affecting human health. Automatic analysis for the gel images can help saving time and labor for biologist in identifying and matching the proteins across the 2D-GE images in which protein spot segmentation is a critical step. In this paper, we present a novel approach for protein spot detection, which is a marker-free watershed that does not require specification of predefined markers for the process of finding watershed contour lines. This approach includes a selective nonlinear filter and pixel intensity distribution analysis for removing local minima which causes over-segmentation when applying watershed transform. It then superimposes those true minima over the reconstructed gradient image before applying watershed transform for spot segmentation. The effectiveness of this marker-free approach was experimentally comparable with other methods.","PeriodicalId":394071,"journal":{"name":"2007 International Symposium on Information Technology Convergence (ISITC 2007)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130357118","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}

However, although such new encoding technology is the main factor in improving the encoding efficiency, it is simultaneously a highly complex factor. Therefore, the H264 standard is used widely in real applications where the speed elevation of these technologies is essential. The proposed fast motion vector search technique supports the fastest compensation of the variable size block motion that is suitable for the motion vector conclusions which comprise a significant proportion of the encoding complexity in this paper. In addition, a fast-mode decision algorithm capable of deciding various encoding optimal values of H.264 is proposed. Because the proposed fast mode decision algorithm is capable of deciding the mode early, the method enables the omission of the computational procedure of rate-distortion cost and the efficient operation of the motion vector search technique. The results presented here confirmed the achievement of a very high efficiency while decreasing the required number of calculations without incurring any significant encoding damage, thereby improving the existing algorithm by using the information of the surrounding block.","PeriodicalId":394071,"journal":{"name":"2007 International Symposium on Information Technology Convergence (ISITC 2007)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122780294","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}
