In this paper, we propose, a novel framework for 3D segmentation of the prostate region from Dynamic Contrast Enhancement Magnetic Resonance Images (DCE-MRI). The framework is based on a maximum aposteriori (MAP) estimate of a new log-likelihood function that consists of three descriptors: (i) 1st-order visual appearance descriptors of the DCE-MRI, (ii) a 3D spatially invariant 2nd-order homogeneity descriptor, and (iii) a 3D prostate shape descriptor. The shape prior is learned from the co-aligned 3D segmented prostate DCE-MRI data. The visual appearances of the object and its background are described with marginal gray-level distributions obtained by separating their mixture over prostate volume. The spatial interactions between the prostate voxels are modeled by a 3D 2nd-order rotation-variant Markov-Gibbs random field (MGRF) of object/background labels with analytically estimated potentials. Experiments with real in vivo prostate DCE-MRI confirm the robustness and accuracy of the proposed approach.","PeriodicalId":308189,"journal":{"name":"The 10th IEEE International Symposium on Signal Processing and Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126414364","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}

Almost each and every organization and financial institutes prefers electronic transaction in lieu of pen-paper based banking approach, which depends on high speed internet technology. However, this online monetary transaction is a long cherished blessing for the developed countries. In developing and underdeveloped countries, SMS banking gets rapid popularity over the internet banking via mobile phone, since internet based m-banking suffers from several limitations of internet connectivity, such as inaccessibility, slow speed, intermittent disruptions, and need for costly handset. In this paper, we propose a scheme where even without having an internet connection within the mobile handset, a client can virtually get the advantage of high speed internet banking via a GSM incorporated SMS transaction. Moreover, security over internet is a burning issue irrespective of the type of transaction, especially when the internet based transactions are operated at the user end. In the proposed scheme, we also offer a newly dimensioned security protocol using digital watermarking technique.","PeriodicalId":308189,"journal":{"name":"The 10th IEEE International Symposium on Signal Processing and Information Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128436238","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}

While being efficient, its performance is far from the state of the art because the vertical consistency between the scanlines is not enforced. 1D optimization based on dynamic programming for stereo correspondence is re-examined by applying it to the vertical consistency between the scanlines as opposed to the individual scanlines. To do this, a pixel is allowed to have a disparity with possibly sub-optimal cost for it in two directions. Thus, the proposed algorithm is a truly global optimization method because disparity estimate at one pixel depends on the disparity estimates at all the other pixels, unlike the scanline based methods. Proposed algorithm is evaluated on the benchmark Middlebury database. The algorithm is very simple, so the proposed algorithm should be a good candidate for real time implementation. The results are considerably better than that of the scanline based methods. While the results are not the state of the art, the proposed algorithm offers a good trade off in terms of accuracy and computational efficiency.","PeriodicalId":308189,"journal":{"name":"The 10th IEEE International Symposium on Signal Processing and Information Technology","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114583677","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}
