The model provides a good security and accuracy about judging the situation of Web page tampering. The classifying theory based on virus is applied when watermark embedded and extracted. The proposed scheme is applied in all kinds of HTML or XML files, not just for English letters but also for the rest of characters. More importantly, it can be restored to the original file completely when the watermark is extracted. Therefore, the proposed scheme, associated with 3rd generation technology of tamper-proof for web pages, exhibits a good property of real-time performance and security. Experiment results show that it overwhelms existing schemes of tamper-proof in that it does not increase the file size and it does not expend great computing time such as cryptography.","PeriodicalId":175885,"journal":{"name":"2008 International Conference on Audio, Language and Image Processing","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134430161","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 the relation between partial convolution and circular convolution, we propose a multi-inconsecutive-frames moving average method to produce new frame for DFT to substitute the mixture frame. Its DFT coefficients could estimate the mixing matrix on each frequency bin more precisely than traditional way, which improves the separation performance.

Nevertheless the issue of how to suitably arrange the macroblocks in suitable FMO mapping type for different video applications is yet to be clarified and investigated. In this paper, we are analyzing the tradeoff and effectiveness of the six fixed FMO types, and based these six fixed FMO types, using the joint source-channel rate distortion optimization (RDO) principle to propose an adaptive FMO type selection strategy for different video scenes and applications. The experiment results shows that our method has more compatibility and flexibility than the six fixed FMO types, and better error resilience than most of them.","PeriodicalId":175885,"journal":{"name":"2008 International Conference on Audio, Language and Image Processing","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132368963","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}

A lot of research has been done to pursue fast algorithms of MDCT and efficient ways of implementation as well. In this paper, a developing roadmap of the fast algorithms of MDCT is firstly presented, followed by the analysis to prove that the three types of MDCT can be unified into any one type to simplify the MDCT computation structure in the AC-3 encoder. In the end, the computation complexity of three unifications is compared. The ones using short transform cores have a tiny advantage in the amount of addition. However, this advantage would be darkened due to more circular shifting which the unifications call for.","PeriodicalId":175885,"journal":{"name":"2008 International Conference on Audio, Language and Image Processing","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133226054","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}

Such statistical modeling systems usually operate slower than real-time, largely because of the heavy computational overhead of the likelihood computation. The objective of our research is to investigate application of modern SIMD technology to speed up the likelihood computation without degrading the recognition accuracy. In this paper, the likelihood computation of continuous density HMMs is analyzed to show that the conventional way of sequential computing is time-consuming and the likelihood computation itself can be implemented in parallel. A SIMD-based algorithm which can carry out parallel likelihood computation is presented in this paper. Likelihood computation modules in HTK3.4 toolkit have been modified with SIMD instructions to implement this algorithm. Experiments on TIMIT and WSJ0 corpora show that the SIMD-based data-level parallelism can significantly reduce the time overhead for likelihood computation.","PeriodicalId":175885,"journal":{"name":"2008 International Conference on Audio, Language and Image Processing","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133420418","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}
