INTRODUCTION Text detection and segmentation from a naturalscene is very useful in many applications. With theincreasing availability of high performance, lowpriced, portable digital imaging devices, the applica-tion of scene text recognition is rapidly expanding. Byusing cameras attached to cellular phones, PDAs, orstandalone digital cameras, we can easily capture thetext occurrences around us, such as street signs, ad-vertisements, traffic warnings or restaurant menus.Automatic recogn… 相似文献

结构理论是源于韩礼德系统功能语法的语篇分析范式中的一个重要理论。语篇结构就是文章的宏观结构,即语类结构,是区分语篇与非语篇的依据。一般来说,在同一文化情境中,相同类型的语篇都有基本相同的语篇结构。通过对语篇结构理论的概述,并利用该理论分析英汉旅游语篇的差异,探讨语篇结构理论对旅游文本汉英翻译有重要指导作用。 相似文献

中国古代文学文本可以划分为记事性文本和象喻性文本两种不同的类型,这种文本类型的差异导致了阐释方式的差异,记事性文本由于其直接的指事陈情,在理解上很容易把握,象喻性文本由于比兴等的运用、主观的差异性,更容易导致阐释上的差异,所以既有客观对象上的文本,也有因主观因素而引起的主观性文本,这种因比兴或象喻的运用以及因具有主观性的人引起的文本差异导致了阐释方式的差异,这种差异的客观存在,需要我们在阐释文本对象时要保持一种宽容性,最后达到一种得意忘言的非主观性的阐释。 相似文献

Using the textbase-situation model of discourse processing and assuming a distinction of learning (recall of text contents) and understanding (relating different parts of text contents or text to non-text contents), it was found that individuals reading text contents from a number of sources who wrote an argumentative essay about the contents and then rated content elements for importance developed a better understanding of the contents than individuals writing a narrative essay and making importance ratings either before or after writing. 相似文献

In three experiments we examined whether reader perspective on a long expository text could be manipulated such that increased text interest and enhancement of two comprehension outcomes would result. In Experiment 1 we verified the viability of a new text for experimental purposes. We then assigned readers a perspective before reading in Experiment 2 and after reading in Experiment 3. One primary research question addressed whether interest in a long expository text could be manipulated by assigning readers a perspective. We considered this to be an examination of purpose-driven interest ( Schraw & Dennison, 1994). As hypothesized, participants rated text segments as more interesting when the segments corresponded to their assigned perspective. In support of our second hypothesis, that recall would increase as a function of reader perspective, low to medium effects were found for both total number and depth of ideas recalled. We discuss implications of this work for understanding of the role of relevance in increasing recall. Implications for practice and future research are also discussed. 相似文献

文本类型翻译理论与翻译标准的再讨论 总被引：4，自引：0，他引：4
不同类型的本需要不同的翻译标准，表达型本的翻译既要忠实原的思想内容，又要忠实原的语言风格；信息型本的翻译要忠实原的“真实性”；号召型本的翻译则要忠实于读的反应。纽马克的本范畴理论为翻译标准的研究提供了新的视点。 相似文献

针对传统文本—图像对抗模型中,由于反卷积网络参数过多容易产生过拟合现象,导致生成图像质量较差,而线性分解方法无法解决文本—图像对抗模型中输入单一的问题,提出一种在线性分解基础上加入流形插值的算法,并对传统 DCGAN 模型进行改进,以提高图像的鲁棒性。仿真实验结果表明,生成花卉图像的 FID分数降低了 4.73%,生成鸟类的 FID 分数降低了 4.11%,在 Oxford-102 和 CUB 两个数据集上生成图像的人类评估分数分别降低了 75.64%和 58.95%,初始分数分别提高 14.88%和 14.39%,说明新模型生成的图片更符合人类视角,图片特征更为丰富。 相似文献

缺乏对篇章结构的认识是目前大学英语阅读教学的一个主要问题。由于传统教学偏重对词和句法的讲解,阅读教学缺乏对篇章的宏观处理,因而制约了学生阅读理解水平的提高。篇章结构作为文本重要的内在特征对提高阅读理解的正确性和效率有着积极作用,采用正确的阅读教学策略,传授篇章结构知识,从长远来看可以大幅提高阅读教学的效率。 相似文献

文学翻译中文化"传真"的制约因素与形象转换 总被引：1，自引：0，他引：1
文学翻译要求译语从文化的角度准确再现原语所要传达的意义,文化"传真"是翻译的理想的目标。由于英汉民族的思维方式和文化背景不同,同一形象所承载的语义可能就不尽相同。为了唤起译语读者脑海里的直接的意象,翻译时应尽可能地保留原语形象,并根据译语的文化及语言习惯决定异化或归化,在再现形象、转换形象、增添形象与舍弃形象之间作出选择。 相似文献

Computer generated images are being used to provide text and diagrams for lectures. These images are then openly available to first year undergraduates in the Department of Mechanical Engineering and Manufacturing Systems at the University of Northumbria. A large lecture theatre is fitted with a computer-driven overhead projector and is used to display the files to over one hundred students. The image files and a text file commentary are provided, via automated routines on department computers, for students to copy onto their own discs.
The images are produced in a compressed and self displaying form, allowing all the material for the course to be contained on a single 1.4Mb floppy disc. All the material associated with these lectures is held on magnetic media.
This paper describes the method used, comments on some of the practical problems of using the method, and gives some of the student reaction to it. 相似文献

Causality has been singled out by several researchers as an important factor in text comprehension and memory. The basic assumption underlying this view is that the perception of causal ties between elements in a text binds the text elements together and enables the reader to construct a coherent representation of the text in memory. Although research findings indicate that causality is a strong predictor of comprehension in narrative texts, the role that causality plays in the comprehension of expository texts has received relatively little attention. In the research reported in this article, a profile of causal development in ten-year-olds was built up on the basis of their recall of history and science texts in which the amount of causal connectivity differed. Four variables were identified and measured, namely length of recall protocols, amount of causal connections recalled from original test passages, amount of causal density and causal hierarchicalization created in the recall protocols. The results of the recall test were also compared to the subjects' English grades. The findings indicate that causal connections play an important role in expository text recall, and that subjects who have a strong causal profile also, generally, perform well in English. The research and pedagogical implications of these findings for reading and writing skills are discussed. 相似文献

许多图像中包含的文本信息对于图像高层语义内容的自动理解、图像索引和检索非常有用。复杂背景图像中文本信息的提取一般包括文字的自动检测、定位、提取、分割和识别,由于图像中文本的大小、字体、字形、位置、排列和图像的清晰度、对比度等不定,使文本自动提取非常困难。文章对目前国内外图像中文本提取主要技术和发展方向进行了综述,便于该领域的研究人员了解和借鉴,同时指出了今后研究方向的热点。 相似文献

This paper analyses the extent to which textbook images are designed using the Instructional Criteria for Image Analysis (ICIA) model in textbooks. The ICIA proposed that learning through images involves interaction between the learner, the image, and the activities with images proposed to the student. Images from the main text and activity section of eleven primary and secondary school textbooks on the human body were analysed regarding the extent to which they fit the proposed criteria. Images in the main text were analysed according to size and type, presence of visual elements (graphical elements, colour, enlarged details), verbal elements (caption, labels) and reference to the image within the text, while images in the activity sections were analysed according to learning involved (task type, procedure, processing level). Results show unequal presence of these criteria in both primary and secondary school textbooks. There are some differences between primary and secondary levels (predominant image type, degree of image contextualisation and processing level required). Images should not be considered self-evident. Images should be designed based less on aesthetic and decorative criteria and more on instructional criteria such as ICIA proposed in order to support image-based learning processes and increase the potential value of images as learning tools. 相似文献
