空间差异度量约束的图像修复

针对传统算法在图像修复时选取最佳块匹配准则的单一性和随机性的问题,提出了一种空间差异度量约束的图像修复方法。该算法利用等照度线确定待修复块的优先级,根据空间差异度量约束的最佳块匹配准则搜索与该待修复块最匹配的样本块,采用最佳匹配块的信息更新优先级最高的待修复块的信息以修复其缺失像素信息。实验结果表明,与传统算法相比,所提算法能有效提高图像修复的主客观质量,对三种类型的信息缺失均取得了较好的修复效果。     

Applying destination attribute segmentation to health tourists: A case study of Polish spa resorts

The present research presents an effective segmentation of visitors to Polish spa resorts and thereby provides useful insights contributing to the understanding of the attributes determining the perceived spa resort’s image and nature of the delineated segments. The research is based on the findings from a self-administered questionnaire, an instrument consisting of 11 pull-motivational items, developed and used in a survey of 2050 Polish spa resort visitors. Based on destination attributes and relevant socio-demographic characteristics, a clustering method identified three distinct segments of visitors to Polish spa resorts.

Destination marketing during and following crises: combating negative images in Asia

The goal of this study is to analyze which strategies Asian officials and marketers have adopted in order to combat stereotypes, negative perceptions, and crises in order to repair destination images and bring back visitors. The study includes qualitative content analyses of news reports, press interviews, and campaigns in order to uncover media policy, strategies, events, and marketing initiatives used since 2008. The conceptual framework used was the “multi-step model for altering place image”, which offers three types of strategies to use in order to repair a destination’s negative image during and after a crisis: source, message, and audience.

现代公关视野下的高职院校形象塑造

求生存,求发展,是每所学校都面临的现实问题。无论是基础较好的重点学校,还是基础较差的一般学校,都需要在竞争中巩固发扬自身优势,形成自己特色,使自己立于不败之地,都要思考在社会、公众中如何树立良好形象、最佳形象的问题。塑造学校形象．是推动学校自主发展的重要策略,它是用提升师生员工的整体素质来提升学校形象,用学校整体形象来增强学校的综合实力和竞争实力。良好的学校形象不仅可以为学校创造发展的契机,而且,还可以为学校增强教育质量,为学校改革与发展提供持久动力。     

基于Matlab的双线性插值算法在图像旋转中的应用

插值运算作为一种标准的运算方法在图像处理领域,尤其是在图像的放大、旋转和卷积处理过程中有着广泛的应用.本文提出了一种新的双线性插值算法,通过对超出图像边界的区域进行取模操作,实现图像阵的循环.采用Matlab编程实现该算法,并应用到图像旋转中.实验证明,用该算法旋转图像时,在特定角度（90.、180.和270.）可以完整显示原始图像;任意角度旋转时,可以看到超出图像范围的像素部分自动进入了斜线对侧,较好地显示出图像旋转的边界变化和旋转位置的循环.     

Investigating the service brand: A customer value perspective

Despite considerable interest in the nature and role of marketing using a service perspective [Vargo S., Lusch R. Evolving to a new dominant logic for marketing. J Mark 2004; 68 (1): 1-17] there is limited research about branding. Research to date tends to be qualitative [e.g., Berry L. Cultivating service brand equity. J Acad Mark Sci 2000; 28: 128-137; de Chernatony L., Segal-Horn S. The criteria for successful services brands. Eur J Mark 2003; 37 (7/8): 1095-1118] rather than quantitative. This research closes this gap by developing and testing a theory of the influence of the service brand on the customer value-loyalty process. The model includes the traditional influence of brand image plus three additional influences that more fully reflect the broader service perspective (company image, employee trust, and company trust). Using survey data of a sample of 552 airline customers, the analysis shows there is a direct influence of all the aspects of the brand on customers' perceptions of value. In addition brand image, company image and employee trust have a mediated influence on customer value through customers' perceptions of service quality. Finally the analysis shows that a service brand does not have a direct influence on customer loyalty but rather its influence is mediated through customer value. This paper concludes with a discussion of the managerial and research implications.     

基于高分二号卫星融合数据的城镇黑臭水体遥感监测研究

为研究通过卫星遥感手段监测城镇黑臭水体位置分布的可行性,利用高分二号卫星融合影像数据对北京市城镇水体进行水体岸线提取和水质参数反演。水质参数包括叶绿素a、悬浮物浓度、透明度和营养化指数。基于水体岸线提取结果和反演的各类水质参数的指数分布图,结合预先设定的水体黑臭程度遥感判别指标,对北京市9处水体河段水质进行综合遥感判读,辅以实地调查验证。研究结果表明,利用高分二号卫星融合影像能够很好的识别城镇区域内宽度较窄的河道岸线,并判定水面浮萍的存在,定量反演出的水体单位面积内悬浮物浓度、透明度和营养状态指数能够反映水体的黑臭程度,各河段水体黑臭程度的遥感判别结果与官方公布的结果基本一致。     

印刷质量过程控制技术发展趋势

本文综合国内外印刷过程控制技术的发展,对当前采用的印刷过程控制技术进行了综合论述。由于颜色测量技术的发展以及图像采集和处理技术不断成熟,这些技术可以应用在印刷机上进行印刷过程控制。通过图像采集技术实现印刷过程中印刷状态信息的实时采集和处理,并将信息反馈给印刷机控制机构实现印刷过程的闭环控制,有望代替目前印刷机已经沿用几十年的CPC墨色控制系统。
