数字经济时代需要信息的流动和分享，但不能牺牲对个人信息安全的保护。立法应对个人信息的法律保护与合理使用两个方面进行规制，分清个人信息保护与个人信息的正常合法利用之间的界限，在未来的《人格权法》中应该给个人信息权独立的法律地位；应针对个人信息权中涉及到的具体的、专门的、特殊性的问题，制定《个人信息权法》及其相关的法律法规，建立起关于个人信息的完整法律体系。
大量移动手机应用（Apps）存在重叠性功能特征，大量用户评论和多个标签，给市场机会发现、开发应用集成和应用选择带来困扰.本文提出基于文本挖掘和相似度网络融合的移动信息服务模式挖掘框架：基于功能描述文本、用户评论、分类标签分别构建个体相似度网络；将从不同信息视角得到的相似度网络进行非线性融合；用聚类验证融合网络有效性，将其用于发现不同移动信息服务模式.最后实验抓取2451个Apps，多视角特征融合方...

基于视差信息的立体图像主动闭合轮廓提取算法研究
闭合轮廓提取 视差信息 贪婪蛇 初始轮廓
2018/5/21
针对立体图像中目标对象的闭合轮廓提取任务，该文提出一种基于视差信息的轮廓提取算法。该算法在传统贪婪蛇模型的基础上，利用各控制点和中心的视差关系为模型设计收缩和膨胀力，能够有效指导初始轮廓曲线向目标边缘的收敛。同时算法采用重复利用经处理的控制点作为模型输入的循环迭代方式，能够获得分布均匀且较为密集的边缘曲线。实验结果表明，该轮廓提取算法减少了传统的贪婪蛇模型算法对初始值的依赖，准确度和可靠性均得到了...
