The effects of festivals and special events on city image design

LIU Yuan, CHEN Chong

《结构与土木工程前沿（英文）》 2007年第1卷第2期页码 255-259 doi: 10.1007/s11709-007-0032-0

摘要： City marketing provides a good vehicle to strengthen a city in competition. On the analysis of the important roles of events and city image in the context of city marketing, this paper suggests that holding festivals or special events is an effective approach to enhance city marketing. The positive impacts of festivals and special events, such as the identification of city image, the promotion of the transmission of city image, and the reversal of the negative image of the city, are discussed. The negative impacts of festivals and special events are also talked about. The unique image of the city could be identified by the City Mind Identity, the City Visual Identity and the City Behavior Identity concerned with festivals and special events.

Research and application of visual location technology for solder paste printing based on machine vision

Luosi WEI, Zongxia JIAO

《机械工程前沿（英文）》 2009年第4卷第2期页码 184-191 doi: 10.1007/s11465-009-0034-9

摘要： A location system is very important for solder paste printing in the process of surface mount technology (SMT). Using machine vision technology to complete the location mission is new and very efficient. This paper presents an integrated visual location system for solder paste printing based on machine vision. The working principle of solder paste printing is introduced and then the design and implementation of the visual location system are described. In the system, two key techniques are completed by secondary development based on VisionPro. One is accurate image location solved by the pattern-based location algorithms of PatMax. The other one is camera calibration that is achieved by image warping technology through the checkerboard plate. Moreover, the system can provide good performances such as high image locating accuracy with 1/40 sub-pixels, high anti-jamming, and high-speed location of objects whose appearance is rotated, scaled, and/or stretched.

NTRU格上基于身份签名的高效方案

《信息与电子工程前沿（英文）》 2016年第17卷第2期页码 135-142 doi: 10.1631/FITEE.1500197

摘要：

Identity-based signature has become an important technique for lightweight authentication as soon as it was proposed in 1984. Thereafter, identity-based signature schemes based on the integer factorization problem and discrete logarithm problem were proposed one after another. Nevertheless, the rapid development of quantum computers makes them insecure. Recently,many efforts have been made to construct identity-based signatures over lattice assumptions against attacks in the quantum era.However, their efficiency is not very satisfactory. In this study, an efficient identity-based signature scheme is presented over the number theory research unit (NTRU) lattice assumption. The new scheme is more efficient than other lattice- and identity-based signature schemes. The new scheme proves to be unforgeable against the adaptively chosen message attack in the random oracle model under the hardness of the γ-shortest vector problem on the NTRU lattice.

标准模型下基于高效分级身份的格上加密方案 Article

Feng-he WANG,Chun-xiao WANG,Zhen-hua LIU

《信息与电子工程前沿（英文）》 2016年第17卷第8期页码 781-791 doi: 10.1631/FITEE.1500219

摘要：本文在标准模型下，利用固定维数的格基代理算法提出了一种高效的格基分级身份加密方案。其公钥尺寸仅为(dm2+mn)log q比特，而消息-密文扩展因子仅为log q，其中d为最大分级深度，(n, m, q)为公开参数。本文构造了一种新的公钥赋值算法，将1个随机、公开的矩阵平均赋值为两个身份比特，从而仅仅需要d个公开矩阵来构造标准模型下的HIBE方案；与之相比，Crypto 2010所提出的HIBE方案中需要2d个同样尺寸的矩阵，公钥尺寸达到(2dm2+mn+m)log q。为了将该方案的消息-密文扩展因子压缩到log q，本文基于Gentry的加密方案建立了一种基础加密算法，一次加密操作中能够加密m2比特明文并得到m2log q比特密文。因此，文中所提方案在公钥尺寸、消息-密文扩展因子等方面具有一定的优势。基于差错学习问题的困难性，我们证明该方案在选择身份、选择明文攻击下是安全的。

Integration of current identity-based district-varied health insurance schemes in China: implications

null

《医学前沿（英文）》 2012年第6卷第1期页码 79-84 doi: 10.1007/s11684-012-0179-5

摘要：

With China’s great efforts to improve public health insurance, clear progress has been achieved toward the ambitious full health insurance coverage strategy for all. The current health insurance schemes in China fall into three categories: urban employee basic health insurance scheme, urban resident scheme, and new rural cooperative medical system. Despite their phasic success, these substantially identity-based, district-varied health insurance schemes have separate operation mechanisms, various administrative institutions, and consequently poor connections. On the other hand, the establishment and implementation of various health insurance schemes provide the preconditioning of more sophisticated social health insurance schemes, the increase in the income of urban and rural people, and the great importance attached by the government. Moreover, the reform of the “Hukou” (household register) system provides economical, official, and institutional bases. Therefore, the establishment of an urban-rural integrated, citizen-based, and nationwide-universal health insurance scheme by the government is critically important to attain equality and national connection. Accordingly, the differences between urban and rural areas should be minimized. In addition, the current schemes, administrative institutions, and networks should be integrated and interconnected. Moreover, more expenditure on health insurance might be essential for the integration despite the settings of global financial crisis. Regardless of the possible challenges in implementation, the proposed new scheme is promising and may be applied in the near future for the benefit of the Chinese people and global health.

基于定量属性的单目标视觉跟踪算法评价体系研究 Article

Wen-jing KANG, Chang LIU, Gong-liang LIU

《信息与电子工程前沿（英文）》 2020年第21卷第3期页码 405-421 doi: 10.1631/FITEE.1900245

摘要：视觉跟踪是计算机视觉领域热门研究课题之一。近年来，很多先进跟踪算法和性能评价基准相继发布，并取得巨大成功。现有评价体系大多定位于衡量整体性能，无法通过针对性的详细论证评估跟踪器的优势和缺点，且很多常用评测指标缺乏令人信服的含义解释。本文从测试数据、测试方法、测试指标3方面深入分析跟踪评价体系的细节。首先，归纳整理了12个反映图像序列不同特性的帧间视觉属性，并首次定量给出其归一化公式。基于这些属性定义，提出两种新的测试方法，即基于相关性的测试和基于权重的测试，使评价体系能更直观、更清晰地评定跟踪器各方面性能。然后，将所提测试方法应用于著名的跟踪挑战赛，即Video Object Tracking (VOT) Challenge 2017。测试结果表明，在目标尺寸快速或剧烈变化时，跟踪器大多表现不佳，即使基于深度学习的先进跟踪器也未能很好解决这一问题。此外发现，中心位置差错（center location error，CLE）性能指标虽未考虑到目标尺度，在实际测试中仍对目标尺寸变化很敏感。

摘要：监督式机器学习方法可自动分类新数据，且对数据分析非常有帮助。监督式机器学习的质量不仅依赖于使用的算法类型，也依赖于用于训练分类器的标注数据集的质量。训练数据集中的标注实例通常依赖于专业分析人员的手工选择与注释，且通常是一个单调与耗时的过程。标签可以在学习过程中为主动学习算法提供有用的输入，以自动确定数据实例的子集。交互式可视化标注技术是有前景的选择，它提供有效的视觉概览，分析人员可从中同时查看数据记录与选择项目标签。将分析人员置于循环中，生成的分类器可得到更高准确率。虽然交互式可视化标注技术的初步结果在某种意义上有前景的，考虑到用户标注可改善监督式学习，但是该技术的许多方面仍有待探索。本文使用mVis工具标注一个多元数据集以比较3种交互式可视化技术（相似图、散点矩阵与平行坐标图）以及主动学习。结果表明3种交互式可视化标注技术的分类准确率均高于主动学习算法，相对于散点矩阵与平行坐标图，用户主观上更偏爱使用相似图标注。用户也可以根据使用的可视化技术采用不同标注策略。

摘要：随着电子信息技术的飞速发展，数字签名已成为人们生活中不可或缺的一部分。由于证书管理的局限性，传统的公钥证书密码系统无法满足现有需求。基于身份的密码系统避免了证书管理问题。量子计算机的发展给传统密码学带来严峻挑战。后量子密码学研究势在必行。目前，几乎所有后量子基于身份的签名方案都是利用高斯采样技术或陷门技术构建的。但是，这两种技术对计算效率有很大影响。为克服该问题，采用Lyubashevsky签名方案构造了格上基于身份的签名方案。基于格上的最短向量问题，该方案既不使用高斯采样技术也不使用陷门技术。在随机谕言机模型中，可以证明该方案对适应性选择的消息和身份攻击是不可伪造的。其安全性级别是强不可伪造的，比其他方案存在性不可伪造的安全性更高。与其他有效方案相比，所提方案在计算复杂度和安全性方面具有优势。

Design of an enhanced visual odometry by building and matching compressive panoramic landmarks online

Wei LU,Zhi-yu XIANG,Ji-lin LIU

《信息与电子工程前沿（英文）》 2015年第16卷第2期页码 152-165 doi: 10.1631/FITEE.1400139

摘要： Efficient and precise localization is a prerequisite for the intelligent navigation of mobile robots. Traditional visual localization systems, such as visual odometry (VO) and simultaneous localization and mapping (SLAM), suffer from two shortcomings: a drift problem caused by accumulated localization error, and erroneous motion estimation due to illumination variation and moving objects. In this paper, we propose an enhanced VO by introducing a panoramic camera into the traditional stereo-only VO system. Benefiting from the 360° field of view, the panoramic camera is responsible for three tasks: (1) detecting road junctions and building a landmark library online; (2) correcting the robot’s position when the landmarks are revisited with any orientation; (3) working as a panoramic compass when the stereo VO cannot provide reliable positioning results. To use the large-sized panoramic images efficiently, the concept of compressed sensing is introduced into the solution and an adaptive compressive feature is presented. Combined with our previous two-stage local binocular bundle adjustment (TLBBA) stereo VO, the new system can obtain reliable positioning results in quasi-real time. Experimental results of challenging long-range tests show that our enhanced VO is much more accurate and robust than the traditional VO, thanks to the compressive panoramic landmarks built online.
