简介:为3D网孔模型的watermarking的支持向量机器(SVM)的使用被调查。SVM广泛地为图象,声音,和录像watermarking被探索了,但是没在3Dwatermarking域被探索标明日期SVM的潜力。建议途径为嵌入的水位标为顶点的选择作为一个二进制分类器利用SVM。SVM被训练,特征向量源于eigen正常和从规范的3D网孔模型拿的顶点的一位1戒指邻居的表面正常之间的尖差别。SVM学会作为修正的适当或不恰当的候选人分类顶点以便提供水位标。试验性的结果证实建议算法对象网孔变光滑那样的攻击细微、柔韧,收割并且噪音增加。
简介:可扩展的标注语言(XML)为在基于万维网的应用代表并且互换数据成为了事实上的标准。并且XML看法,为指定用户的一扇虚拟窗户,广泛地被使用了。在实际系统,当他们需要通过看法更新来源数据时,用户们遇到所谓的看法更改问题。很长时间,看法更改问题是在数据库社区的一个待研究的问题。与各种各样的数据模型的开发,相应看法更改问题广泛地被研究了。在这篇论文,我们介绍看法更改问题的概念。我们调查并且比较以前的途径。特别,我们强调语义的角色。在XML上下文集中于这个问题,我们给讨论并且建议一个框架,它在看法定义时间收集语义信息。为实现这个框架的一些相关技术进一步被介绍。
