KAFD Arabic font database

Font recognition is useful for improving optical text recognition systems’ accuracy and time, and to restore the documents’ original formats. This paper addresses a need for Arabic font recognition research by introducing an Arabic font recognition database consisting of 40 fonts, 10 sizes (ranging from 8 to 24 points) and 4 styles (viz. normal, bold, italic, and bold–italic). The database is split into three sets (viz. training, validation, and testing). The database is freely available to researchers.¹ Moreover, we introduce a baseline font recognition system for benchmarking purposes, and report identification rates on our KAFD database and the Arabic Printed Text Image (APTI) database with 20 and 10 fonts, respectively. The best recognition rates are achieved using log-Gabor filters.     

TrueType字体自动打标机软件设计

通过分析TrueType字体文件结构和提取出字符轮廓信息,实现了对字符的无失真任意放大和缩小以及旋转等特效,曲线轮廓可以进行填充。将二次Bezier曲线构成的字符轮廓,通过最小二分法转换成一组能够保持曲线轮廓形状的小折线,将原有的字体轮廓数据从用曲线轮廓表示转变为用多边形顶点控制,用一组点及其先后顺序来描述轮廓。研究了字形交叉的消隐处理方法,解决了笔画重叠的问题。打标机将得到的多边形顶点信息准确打标。

浅析汉字字体的审美表情及其分类优选

字体表情自汉字诞生之初业已存在,其发展变化的助推力来源于人类从不间断的文明进程。印刷术的推广加快了字体审美表情的演变速度。当下汉字字体的结构韵律及审美表情千姿百态,与汉民族性格存在一定的映射效应。汉字字体借鉴诸多西方字体的结构特征,形态日渐丰富多样。为期达到最佳审美及实用功效,应根据字体的审美表情差异对汉字字体进行分类优选。     

字库开发的形态调整规则与设计方法

目的研究新字库开发过程中的形态调整规则及设计方法,提升字库开发的质量。方法基于中国传统书法体与印刷体的美学概念,结合现代信息传播条件下新字库的应用需求,归纳字库开发中的形态调整规则,并剖析在中英文字库产业化研发中的创意设计方法。结论在中英文新字库开发的产业化及规模化过程中,以字体的灰度均衡、重心调节、缩放调整、结构均衡为核心的形态调整规则,是提升产品质量的保证;同时,采用多种设计方法进行整合与推演,能够提升新字库研发的创意效率。     

基于VxWorks的OpenGL图形界面开发

提出一种基于VxWorks的OpenGL图形界面开发方法。研究VxWorks下的OpenGL图形解决方案及汉字生成的基本原理,提取字符的点阵信息生成点阵字体,使用FreeType产生矢量字体。将字体以OpenGL的方式绘制在图形中,实现基于VxWorks的中文图形界面。应用结果表明,该方法具有可行性和实用性。     

一种面向维文网站的动态天气图文信息服务支持系统

维吾尔文地理信息服务的研究与应用的匮乏,使维吾尔用户很难享受基于本民族语言的地理信息服务。该文以新疆动态天气图文信息服务为例,提出了一种面向维文网站的WebGIS服务解决方案。方案首先通过集成免费Google Maps API地图服务和实时免费Yahoo Weather RSS天气信息,制作新疆县域维吾尔文天气信息服务模块;其次,将该模块作为引用对象,根据用户对动态天气图文信息服务框架大小和位置的设定,个性化地嵌入到任意维吾尔文大众网站中,使更广大的维吾尔用户享受WebGIS带来的信息服务。该研究推动了WebGIS在维吾尔语语境的新应用,为新疆各族群众提供了便捷动态天气图文信息服务。     

水书键盘输入系统研究与实现

水族文字被称为水书。为了满足水书研究者和出版业界的需要,设计了水字字符集的Unicode编码,利用字体制作软件建立了水字TrueType字库。该文提出了一种基于笔形特征的编码方法,依据编码规则取水字3个角的笔形组成有序序列,为水字编码。利用Windows系统的IMM-IME机制,实现了水字笔形输入法。     

A crucial experiment resubmitted.

Presents the "experiment" conducted by the prophet Elijah in 1 Kings 18:17–40 in which the priests of Baal and Elijah each sacrificed a bull and invoked the name of their respective god, but only Elijah's god responded. Satirical comments of 3 "reviewers" of psychological articles are included to show the ethical and methodological issues that might be raised if such an experiment were conducted today.

Effects of display factors on Chinese proofreading performance and preferences

This experiment investigated the influence of four display factors, viz. typeface (Ming Liu and Jheng Hei), font size (10-point and 14-point), text direction (horizontal and vertical) and copy placement (left-right and top-bottom) on Chinese proofreading performance and subjective preferences. Proofreading performance was measured in terms of time and accuracy, and preferences were examined in terms of comfort, ease and fatigue. It was found that the horizontal text direction resulted in faster proofreading than the vertical one, but the other three factors were non significant. The faster proofreading using the horizontal text direction was valid for both the left-right and the top-bottom arrangements. There was an interaction between typeface and font size such that, for the smaller character size (10-point), the Ming Liu style produced a faster performance than the Jheng Hei style. However, for the larger character size (14-point), the Jheng Hei style produced a faster performance than the Ming Liu style. Regarding proofreading accuracy, the number of non-detected missing words and related false alarm in left-right copy placement setting was significantly larger than that in top-down setting. Greater accuracy was obtained in proofreading at the cost of a speed-accuracy trade-off – the higher the accuracy in the proofreading task, the longer the proofreading time. Font size and text direction had significant effects on proofreading preferences, but typeface and copy placement did not.

Practitioner Summary: This study examined four display factors on Chinese proofreading performance and subjective preferences. The findings of this experiment provide information and recommendations that should prove useful for the design of proofreading interfaces to improve proofreading time and accuracy, and to satisfy proofreaders' preference.
