An experimental study to investigate the impact of image interactivity on the perception of luxury in an online shopping context

The current study investigates whether image interactivity can positively influence luxury perceptions in a virtual shopping environment, by offering shoppers a feeling of telepresence. 185 respondents were referred to either an image interactive or non-interactive virtual luxury store and completed an online questionnaire afterwards to measure their luxury perception. The results of this study show that image interactivity leads to higher perceptions of exclusivity, quality, hedonism and extended self due to a higher perceived telepresence. This study offers some guidelines for luxury brands to retain their luxury perception high in a virtual shopping environment.     

汽车倾斜牌照中字符的定位与提取

提出了汽车图像中倾斜汽车牌照字符的定位与提取算法。该算法针对汽车牌照的灰度特点,先确定牌照的位置,并从背景中分割出来。对二值化车牌定位图通过Hough变换,计算出车牌主要直线的倾斜角度,通过插值旋转后,重新确定车牌字符的边界,最后精确地提取出汽车牌照中的字符。与其它传统的方法比较,该方法在运算速度和精确性上有一定优势。

一种基于孪生神经网络的深度异构网络嵌入算法

针对现有异构网络嵌入方法导致的捕获关系冗余和模糊的问题,提出了一种基于孪生神经网络的深度异构网络嵌入模型。首先,基于面向关系的深度嵌入(Relation-Oriented Deep Embedding,RODE)框架构建了异构网络嵌入模型,以区分同型节点和异型节点之间的关系;其次,将同型节点与异类节点之间的相似性近似到低维空间,通过构建多任务的孪生神经网络来实现节点之间结构和语义关系的深度嵌入;最后,选取四个数据集执行典型网络挖掘任务,并与其他六种算法进行实验对比分析。实验结果表明,保持相同类型节点之间的相似性有助于提高节点分类效率,且损失函数在提高异构网络嵌入质量方面具有良好的优越性;RODE模型能够有效提高稀疏网络的嵌入质量,且具有良好的稳定性和鲁棒性。     

Urban sprawl factors in the surface water resource basins of Istanbul

This paper presents the reasons for uncontrolled land-use changes in the water resource basins of Istanbul. These changes are evaluated with a Geographical Information System (GIS), using four Landsat (1990, 1995, 2000, 2005) satellite images. Additional spatial information about capital improvement projects (highways and the Bosporus bridges), industrial land-use decisions, land ownership, and jurisdictional boundaries is also utilized. We observe that the most critical land-use changes have occurred in places with higher accessibility, mostly in close proximity to the metropolitan city center. The literature describes large public capital improvement projects (primarily the Trans European Motorway – TEM) as the primary reason for a trend of illegal occupation of public lands; however, the TEM should not be considered as the sole reason. This study explores other possible causes for these illegal developments in the water resource basins, grouped into three broad dimensions physical, socio–economic–political, and legal. Finally, we put forward possible policy suggestions for the preservation of the limited surface water resource basins in Istanbul.

基于内容查询的图像数据多层模型和快速检索研究

基于内容的图像搜索是目前搜索领域的研究热点,取得了较大的成果,在实际的开发中对于图像的数据库存储和检索的要求较高。本文通过对图像特征的研究,采用了面向对象的多层数据模型,并分析了索引空间中的多维索引降维、向量空间、度量空间等方法,引出了基于预分类和预计算相似度、树索引和二分快速检索图像数据的方法。接着通过分析其工作流程,从数据模型和检索方法上进行了论述,构造了基于内容的图像检索的工作架构。本文总结了此方案的创新点和适用范围,从而在理论证明了它的优秀的检索性能。最终提出了采用此方案进行基于内容的图像查询的可行途径。

A model of community-based festival image

This study initiates an original inquiry into the image of community-based festivals (CBFs). A CBF image model was proposed and empirically tested based on existing destination image models. Four image constructs were identified as Attributes, Family and Friendliness, Affective Association, and Overall Evaluation. The interrelationships among these constructs were tested by structural equation modeling. The findings revealed that Attributes affects Family and Friendliness and Affective Association, which in turn, affects Overall Evaluation. This study also included visitor loyalty in the understanding of CBF image. It was found that repeat visitors had more favorable perceptions of the CBF than did first-time visitors. Significant perceptual differences were found in Family and Friendliness, Affective Association, and Overall Evaluation between the two groups of festival goers. In addition, it was revealed that loyalty exerted significantly negative interaction effects on the relationship between Attributes and Family and Friendliness, as well as the linkage between Family and Friendliness and Overall Evaluation. In addition, this study illustrated the importance of the support of local residents for CBFs. CBF planners and local tourism organizations would benefit from this study in terms of cultivating visitor loyalty to these festivals and building the destination's brand.
