基于改进神经网络的图像生物特征识别方法   总被引：2，自引：0，他引：2  

曾爱林 《科技通报》2015,(2):224-226

在图像的固定生物特征识别过程中,传统的识别方法针对像素质量不高的问题,很难建立完整的寻优计算过程,识别效果不好。提出基于改进神经网络算法的图像特征识别方法。通过量子计算对神经网络进行优化,优化神经网络在特征识别中的阀值确定过程,完成图像识别。实验结果表明,利用改进的算法进行图像特征识别,能够极大的提高生物特征识别的准确性,扩展了应用的范围。  相似文献   

Photo-elicitation: reflexivity on method,analysis, and graphic portraits     

Veronica M. Richard  Maria K.E. Lahman 《International Journal of Research & Method in Education》2015,38(1):3-22

In this methodological discussion, the authors detail and reflect on the processes of using photo-elicitation interviewing as a way to align with positive qualitative methodologies, to gain access to participant beliefs and values, and to highlight participant voices through their choices of words and visuals. A review of the literature and an overview of the educational research experiences leading to the discussion are included. Next, the discoveries regarding what is methodologically new and/or valuable concerning this visual method is presented. In the final section, the authors reflexively contemplate aspects of visual methodological processes in an effort to address methodological crossroads of potential and tension including: (1) the potential of decontextualized photos, (2) photos as metaphors of meaning, (3) photos as representations of inherent meaning, (4) participant empowerment, and (5) graphic representation or graphic portraits.  相似文献   

生命空间再现:云南甲马的视觉文化与图像意识     

罗杰 《怀化学院学报》2015,(1)

云南甲马是云南民俗艺术中最具地方特色的类型之一,云南甲马作为民众民俗文化的精神体现,集中反映了云南地区民众的传统文化、宗教信仰原貌,呈现了人们对理想生活的精神信仰与祈福的心理诉求。从生命美学的视角出发,运用视觉文化中语义的内涵与外延构成原理,探究云南甲马视觉文化内涵中祈愿避灾的生命意识及其图画表意与文字传情相结合图像意识的生成,进而分析这种民俗艺术构建起的生命空间。  相似文献   

核心图形及其系统生成方式探析     

丁耀 《鸡西大学学报》2011,(12):150-151

核心图形和徽标是大型企业或重要活动的视觉识别系统中的两大核心要素。主要探讨核心图形的系统化设计以及生成方式,指出核心图形的系统化生成主要有“对完整图形的解构、单元形的强调和重复、灵活地模块组合”这三种方式,通过这项研究,有利于在纷繁复杂的视觉环境中建构清晰的信息体系。  相似文献   

论奇观电影     

杨学森 《鸡西大学学报》2011,11(8):111-112

随着现代科技的迅猛发展,一种新的电影样式——奇观电影出现了。奇观电影的出现主要来自两个转变,即传统印刷媒介向现代电子媒介的转变和传统叙事电影向现代奇观电影观念的转变。总体说来,当代奇观电影主要有三种类型：身体奇观,速度奇观,场景奇观。奇观电影一方面给消费时代的受众群体以极大的视觉满足,但另一方面却削弱了传统电影以人类的终极关怀为中心的思想深度。  相似文献   

Strategic library and information services models for the visually impaired persons: The South African Library for the Blind perspective     

Neli Kaunda 《Journal Of Access Services》2019,16(1):34-52

The South African Library for the Blind (SALB) contributes to the quality of life of print-impaired people encouraging independence through access to information, informed decision making, and taking pleasure in the enjoyment of recreational reading. In realizing the vision, SALB implemented two strategic models; agent mini-libraries and comprehensive mini-libraries. Management and administration of the services rendered is covered in detail. The project was pioneered in one of the provinces and has been rolled out to other provinces. The paper highlights how visually impaired people experience in a tangible manner, assistive technologies, training and interaction with community members and use libraries.  相似文献

Girls’ active identities: navigating othering discourses of femininity,bodies and physical education     

Joanne Hill 《Gender and education》2015,27(6):666-684

Within physical education and sport, girls must navigate discourses of valued athletic and gendered bodies that marginalise or ‘other’ non-normative performances through systems of surveillance and punishment. The purpose of this paper is to share girls’ perspectives on how these discourses affected their gender performances and activity engagement. Students aged 13–14 in one ethnically diverse UK secondary school were invited to create a photo diary of the physical activities they engaged in. Photo-elicitation interviews in small groups followed. The girls positioned themselves as physically active but had to carefully manage their activity choices and gender performances in a single-sex physical education environment that regulated deviation from the fit, slender, girly-girl. Although the girls demonstrate the difficulty of resisting, they indicate moments of positioning themselves against norms that suggest the possibilities of shifting gendering processes. The paper points out the importance of listening to ‘other’ girls’ narratives in building positive physical education engagements.  相似文献   

The Efficacy of Using Diagrams When Solving Probability Word Problems in College   总被引：1，自引：1，他引：0  

Brian D. Beitzel  Richard K. Staley 《Journal of Experimental Education》2015,83(1):130-145

Previous experiments have shown a deleterious effect of visual representations on college students’ ability to solve total- and joint-probability word problems. The present experiments used conditional-probability problems, known to be more difficult than total- and joint-probability problems. The diagram group was instructed in how to use tree diagrams to solve conditional probability problems; the equation-only group was instructed only in the formulation of equations. Results indicated that the diagram group outperformed the equation-only group on a posttest of 10 near- and far-transfer problems given immediately and as long as 1 week later (Experiment 2). In addition, when rating their experience with the training phase the equation-only group reported significantly higher levels of frustration and lower levels of perceived success than the diagram group.  相似文献   

一种基于关系视频盲水印算法     

鲁晓辉 《宁波职业技术学院学报》2015,(3)

针对视频水印的特征,提出一种利用视频帧采样点均值曲线相交性确定嵌入帧的方法：在水印信息嵌入时,利用嵌入帧三个亮度最大分块位置关系和DC值大小实现每帧2bit信息的嵌入。实验证明,该算法对常规攻击具有良好的鲁棒性。  相似文献
