INTRODUCTION A common method for extracting depth in-formation from intensity images is based on theprinciples of stereovision. In this method, a pair ofimages is obtained using two cameras displacedfrom each other by a known distance. After deter-mining the stereo correspondence, the distance ofvarious points is computed using triangulation(Jeon et al., 2001). Stereo correspondence is theproblem of finding corresponding points in two ormore images of the same scene, usually assumin… 相似文献

Cultural differences have a great effect on English learning,especially on college English reading.Reading is a crucial tool in acquiring information and knowledge.Culture cannot be separated from language.College English reading should focus on the differences of culture.It is important to understand how to lay stress on the differences in the course of college English teaching and learning about reading for increasing students’ ability of reading.This thesis analyzes the influence of culture on English reading and tries to set up a principle of teaching English through culture.To support my point of view,the relationship between language and culture is discussed first.Language is a part of culture and shaped by culture;it is also the carrier of culture and reflects cultural features of a community in which the language is spoken.Language and culture are closely related with each other.From the aspect of language teaching and learning,to teach a foreign language is to teach another culture;to learn a language is also to learn another culture. 相似文献

The paper deals with the investigation of gender differences in performances in mathematics for Italian students at the end of lower secondary school. The study is based on a new large-scale assessment test developed and administered by the National Evaluation Institute for the School System. Given the evidence in the literature which favors males, performances of female and male students are compared using different approaches. Scores proposed by educational experts based on item subgroups were considered, while a model-based approach was used within item response theory. The results revealed a significant advantage to males in overall performance, while no meaningful differences were observed with respect to item domain and type. An interpretable item map was developed crossing expert opinions with IRT abilities, and plausible proficiency levels were defined. According to the map-based student classification, a relatively lower percentage of females fell into the highest proficiency groups with respect to males. 相似文献

This study was conducted to investigate Taiwan University students' perceptions (including experience, confidence and preference) of online academic help seeking (OAHS) and students' level of web-based learning self-efficacy (WLSE). Two instruments, OAHS questionnaire, consisting of information searching, formal and informal query scales, and WLSE questionnaire, including general and functional scales, were then validated through collecting the responses from 300 university students. Results indicate reciprocal relations between experience, confidence and preference in students' online academic help seeking behaviors. Students' academic help seeking behaviors were related to their general self-efficacy in a web-based course setting. Students' functional WLSE was related to their perceptions of information searching for OAHS. Findings of this study also imply that students' experience of seeking help from informal online channels is prominent when they participate in a web-based course. 相似文献

私小说是产生于日本 ,影响到中国现代文学的一种小说形式。中、日私小说存在着明显的差异。日本私小说的“自我”是自我封闭、不求进取 ,向内深深的反省 ;而中国私小说中的“自我”却在喟叹感伤中潜伏着进取、反抗、并伺机向外扩张个性。造成这种差异的原因 ,主要是因为作家的个人境遇、社会文化和时代背景的不同 相似文献

时代不同,诗歌情感自然呈现差异.本为悲情萦绕的送别诗,在盛唐和晚唐却有着不一样的滋味,这不仅仅是“悲”的程度深浅所能概括的。笔者以《文苑英华》所收诗歌为例,并重点分析送人赴任之作,以突现其差异。 相似文献

本文证明了PVDF与at-PMMA共混物中两者之间非常弱的相互作用 .随着PVDF质量分数的提高 ,共混物显示出更为异相的性质 .通过红外光谱的示差扫描技术 ,减去共混物谱图中PVDF和at-PMMA的谱图 ,显示在高PVDF含量时 ,υc=o吸收峰向低波数移动 ,表明它们之间的相互作用存在于PMMA的羰基和PVDF的H原子之间 .接触角测量表明随着PVDF含量的提高 ,膜的憎水性增强 .当PVDF的含量超过 30 % (质量 % )时 ,对水的接触角大于 90° ,显示了优异的憎水性 .但是 ,膜可以被正己烷完全润湿 ,因而对正己烷的接触角测量不到 相似文献
