基于显著区域提取的红外图像舰船目标检测

针对复杂海面背景下红外图像舰船目标由于灰度不均匀、海杂波干扰大等因素造成的自动检测虚警率高、准确率低的问题，提出了一种显著区域提取和目标精确分割相结合的红外舰船目标检测方法。首先，利用基于图论的视觉显著性(Graph-based Visual Saliency ,GBVS)模型计算待检测图像的显著图，使得目标区域信息增强；其次，结合舰船目标先验信息（长短轴、面积等），利用多级阈值划分算法提取关注的显著区域，并确定原图中候选目标区域；最后，利用空间约束模糊C均值(Fuzzy C-Means,FCM)算法对候选区域进行分割，结合目标先验知识对分割区域筛选并输出目标位置。所提方法在公开数据集IRShips上与相关方法进行比较，结果表明，相比直接进行全图目标搜索的方法，所提方法不仅准确率高、执行速度快，且检测目标的位置更加精确。     

跨文化背景下商业广告设计的视觉元素关注度研究——以餐饮类平面广告为例

本文以餐饮类平面广告为实验材料,研究了中国和美国被试者对平面广告中的图形、色彩、文字、编排及构图等视觉元素的关注度。本研究从文化认知理论出发,以文化认知差异为前提,探寻了东西方族群对商业广告中出现的视觉信息的不同处理方式。以商业广告中视觉设计的原则为标准,解构了平面广告设计中的视觉构成元素并进行一一比较,得出商业平面广告设计中中美两国被试者的视觉元素关注度差异。最终获取了各种视觉元素的评估结果和相对权重,形成了商业图形广告设计元素关注度的先后顺序。这一实验结果对跨文化认知心理理论在跨国广告设计中的应用有借鉴和启发作用,可以为跨国公司和设计师提供技术指导,设计出更符合消费者需求的商业广告。     

Eye-tracking evidence that happy faces impair verbal message comprehension: the case of health warnings in direct-to-consumer pharmaceutical television commercials

Risk warning or disclosure information in advertising is only effective in correcting consumers’ judgments if enough cognitive capacity is available to process that information. Hence, comprehension of verbal warnings in TV commercials may suffer if accompanied by positive visual elements. This research addresses this concern about cross-modality interference in the context of direct-to-consumer (DTC) pharmaceutical commercials in the United States by experimentally testing whether positive facial expressions reduce consumers’ understanding of the mandated health warning. A content analysis of a sample of DTC commercials reveals that positive facial expressions are more prevalent during the verbal warning act of the commercials than during the other acts. An eye-tracking experiment conducted with specially produced DTC commercials, which vary the valence of characters’ facial expressions during the health warning, provides evidence that happy faces reduce objective comprehension of the warning.     

旅游地空间商品化的形式与影响研究--以云南省丽江古城为例

20世纪70年代法国学者亨利·勒菲弗尔(Henri Lefebvre)提出"空间生产理论",认为空间是在人类主体的有意识活动中被不断生产出来的.如果以勒菲弗尔(Lefebvre)空间生产概念为分析工具,旅游地空间也是在发展旅游业、刺激民众消费、获取经济效益等社会背景下被创造、生产出来的.人们以符号的制造与运用赋予地方价值,再把地方意象赋予实质可消费物品,提高商品的交换价值.旅游生产系统通过销售"地方",获取多重服务与消费之后的利润;游客则借由消费内含了丰富地方意象的物质商品和服务而消费地方.文章以社会学和旅游研究中的分析概念为工具,以丽江古城为案例,尝试分析在具有自然或文化特性的旅游地,地方符号被应用于商品消费的具体方式,以及具公共性的观光空间,如何被纳入到私人商品消费的范畴,并由此探究旅游地空间商品化的过程以及空间商品化对当地社会文化的影响,希望对今天的地方旅游规划和文化保护工作有所帮助.     

Corporate rebranding: effects of corporate visual identity changes on employees and consumers

Many organizations invest periodically in a new corporate visual identity (CVI). This study investigates the main effects of CVI changes in four organizations, taking into account three independent variables: stakeholder type (employees vs. consumers), the specific organization, and communication about the CVI change. The results show that CVI changes had positive effects on CVI appreciation and identity/image. However, the effects were different for employees and consumers and differed between specific organizations. Furthermore, adequate communication about the new CVI appeared to be important for people’s appreciation of the CVI. The implications of these findings are discussed.     

Lost and found: Individual differences in propensity to process visual elements of persuasion

Visual processing style, defined as the relative propensity to engage in visual processing rather than verbal processing, is an individual difference variable that has been frequently investigated in the consumer psychology literature. Surprisingly, numerous studies have reported no relationship between visual processing style and viewer responses to visual elements of persuasion. We argue that this accumulation of null results is due to untenable historical theoretical assumptions that underlie the construct, along with methodological problems that are inevitably brought about by those theoretical assumptions. We reconceptualize visual processing style and test an alternative empirical operationalization of it. Using both new data and a reanalysis of data published in the Journal of Consumer Research, we find the old approach yields null results, but we find the new approach yields the expected results. The new approach reinstates the utility of incorporating propensity to engage in visual processing as an individual difference variable into consumer psychology models of visual persuasion, and it reinstates a powerful individual difference variable that can help push forward the investigation of the unique aspects of visual persuasion.

品牌标识的隐性设计线索对消费者品牌创造性感知的影响

从品牌标识的隐性设计线索特征视角切入，基于图底反转原理和溢出效用，本文研究旨在探究品牌标识的隐性设计线索对消费者品牌创造性感知的作用机理。三个实验研究结果表明：品牌标识的隐性设计线索比显性设计线索更能够增加消费者品牌创造性感知，且此效用成立的条件为：消费者自主发现隐性设计线索。同时，消费者的感知有趣性中介了此效用。此外，产品视觉审美集中度正向强化了品牌标识的隐性设计线索对品牌创造性感知的影响作用。     

Let Their Voices Be Seen: Exploring Mental Mapping as a Feminist Visual Methodology for the Study of Migrant Women

This article explores how mental mapping can be used as a critical methodology for feminist migration studies. In a case study of female marriage migrants who settle in rural areas in South Korea from other Asian countries, I attempt to develop mental mapping to supplement verbal interviews. Mental maps of hometowns and current neighborhoods drawn by my interviewees represent their geographical imaginations and complex identity negotiations that mirror the change in their social locations. In order to understand multilayered meanings embedded in the images and the way in which power relations existent between the researcher and the researched affect the map production, I suggest a critical reading of the maps. The article shows how a reflexive and intertextual reading makes a difference to the interpretation of the maps. It argues that the maps are not mere reflections of the women's cognition, but rather socially constructed texts through which their desires, emotions, feelings and internal contradictions are expressed and negotiated. My research suggests that mental mapping, if ethically performed and critically evaluated, has potential as a means to convey the unheard voices of the marginalized to diverse audiences.
