PDEs, especially those that are elliptic in nature, enable surface modelling to be defined as boundary-value problems. Here we show how the PDE based on the Biharmonic equation subject to suitable boundary conditions can be used for shape modelling within visual cyberworlds. We discuss an analytic solution formulation for the Biharmonic equation which allows us to define a function based geometry whereby the resulting geometry can be visualised efficiently at arbitrary levels of shape resolutions. In particular, we discuss how function based PDE surfaces can be readily integrated within VRML and X3D environments.","PeriodicalId":169421,"journal":{"name":"International Conference on Cyberworlds","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129470395","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}

It can exist independently from human control and can (inter)act autonomously in an electronic system. Since the Internet virtual identities (VIDs) are step by step interwoven in (trans)actions of persons but neglected in the law of persons and property. Most people don't realise that they are using VIDs when entering a marketplace (such as eBay), a chat room, or a dating site. They take for granted that an artificial identity is representing them. Given the emerging use of auction and transaction websites the sometimes public backlash against virtual shapes is not proportional to the daily growing accounts that use virtual identities for social and commercial transactions. This paper describes the legal aspects of virtual identities in the context of virtual environments.","PeriodicalId":169421,"journal":{"name":"International Conference on Cyberworlds","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134455592","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}

It is clear that if we continue to deal with cyberworlds as we have been, they grow chaotic beyond human understanding and control, endangering the real world. In an effort to make cyberworlds an academic discipline to overcome the critical situation, we axiomatize cyberworlds and then theorize them as Euclid did in identifying shapes in the real world.","PeriodicalId":169421,"journal":{"name":"International Conference on Cyberworlds","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123854750","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}

In order to detect the moving objects accurately, this paper proposes to remove the moving shadows based on the similarity between little textured patches. The potential shadow points are detected by analyzing the intensity and color properties firstly, and then, the shadow detection approach is improved by evaluating the textural similarity between the current frame and the corresponding background model. Experiment results on both indoor and outdoor scenes exhibit that the proposed method succeeds in removing shadows robustly and achieves the real-time performance.","PeriodicalId":169421,"journal":{"name":"International Conference on Cyberworlds","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114515864","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}

Many techniques have been proposed in the literature involving crypto-biometric algorithm, template transformation method and watermarking reinforcement scheme. Watermarking reinforcement relying on biometrics usually combines the watermarking technique with a feature transformation scheme. We present a new watermarking reinforcement scheme including two security levels to protect biometric data. The first security level is proposed to verify the integrity of the fingerprint while transmitted or stored based on a watermarking approach. To avoid any registration of the stored biometric template, a second security level is developed based on cancellable transformation. The watermarking of the fingerprint image is applied in the wavelet packet decomposition multiresolution domain using a binary watermark derived from the fingerprint minutiae. The developed transformation is designed to explore the relative relation between minutiae in the pair-polar coordinate domain. The transformed minutiae satisfy the non-invertibility recovery of the original ones. Under various scenarios, the suggested scheme is evaluated using the public fingerprint database BioSecure and FVC2002 DB1. The realized testing and derived results show the robustness of the first security level under various attacks and the satisfaction of the second level security to protect biometrics template with an insignificant degradation of the authentication performance.","PeriodicalId":169421,"journal":{"name":"International Conference on Cyberworlds","volume":"355 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122059222","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}
