Journal of Signal and Information Processing 2012年第3期3卷 364-367页

作者： Jayashree r. Pansare Shravan H. Gawande maya Ingle devi Ahilya University m. E. Society’s College of Engineering

Hand gestures are powerful means of communication among humans and sign language is the most natural and expressive way of communication for dump and deaf people. In this work, real-time hand gesture system is proposed. Experimental setup of the system uses fixed position low-cost web camera with 10 mega pixel resolution mounted on the top of monitor of computer which captures snapshot using red Green Blue [rGB] color space from fixed distance. This work is divided into four stages such as image preprocessing, region extraction, feature extraction, feature matching. First stage converts captured rGB image into binary image using gray threshold method with noise removed using median filter [medfilt2] and Guassian filter, followed by morphological operations. Second stage extracts hand region using blob and crop is applied for getting region of interest and then “Sobel” edge detection is applied on extracted region. Third stage produces feature vector as centroid and area of edge, which will be compared with feature vectors of a training dataset of gestures using Euclidian distance in the fourth stage. Least Euclidian distance gives recognition of perfect matching gesture for display of ASL alphabet, meaningful words using file handling. This paper includes experiments for 26 static hand gestures related to A-Z alphabets. Training dataset consists of 100 samples of each ASL symbol in different lightning conditions, different sizes and shapes of hand. This gesture recognition system can reliably recognize single-hand gestures in real time and can achieve a 90.19% recognition rate in complex background with a “minimum-possible constraints” approach.

背景:巴基斯坦是世界第6位结核病高负担国家。据世界卫生组织(WHO)估计,巴基斯坦结核病发病率为181/10万,全国每年新增结核病患者28.6万例。来自于医院的资料表明:巴基斯坦耐多药结核病(mDr-TB)问题已十分严重,急需在社区水平对耐多药结核病的严重程度开展评估。本研究为针对巴基斯坦耐药结核病流行状况开展的横段面研究,所使用的痰标本来自于巴基斯坦全国742例未经治疗的新诊断的肺结核患者。目的:评估巴基斯坦原发性耐药的流行情况结果:在672例痰培养阳性患者中,有76例(11.3%)出现了对1种或多种抗结核药物耐药。36例(5.4%)患者对链霉素(10μg/ml)耐药; 51例(7.6%)患者对异烟肼(1μg/ml)耐药;15例(2.2%)患者对利福平(5μg/ml)耐药;12例(1.8%)患者对乙胺丁醇(10μg/ml)耐药;22例(3.3%)患者对吡嗪酰胺耐药。有46例(6.8%)患者痰标本中分离的结核菌株耐1种抗结核药物, 10例(1.5%)同时耐2种抗结核药物,12例(1.8%)同时耐3种抗结核药物,6例(0.9%)同时耐4种抗结核药物,2例(0.3%)同时耐全部5种抗结核一线药。原发性耐多药率为1.8%,(n= 12)(异烟肼1μg/ml,利福平5μg/ml)。结论:研究结果表明,巴基斯坦原发性耐多药率<2%,需要进一步实施有效的DOTS策略。

斯里兰卡学生汉语标点符号习得偏误分析

斯里兰卡学生汉语标点符号习得偏误分析

汉语标点符号始终是斯里兰卡学生汉语学习的重点,也是汉语学习的难点。汉语的书面表达与标点符号的使用是密切相关的。僧伽罗语与汉语是两种不同的语言,尤其是标点符号这一方面更是存在许多不同点。大多数的斯里兰卡学生在学习汉语时觉得汉语标点符号的理解较为困难,因此在这一方面很容易出现使用偏误。因此,笔者将《斯里兰卡学生汉语标点符号习得偏误分析》作为本论文的题目,试图通过找出斯里兰卡学生学习汉语标点时产生偏误的原因,从而提出一些相应的改进意见。本文通过对凯拉尼亚大学的50名大二学生,以及四所高中:Gampaha Bandaranayake 学校、Vishaka 学校、Yashodhara 学校和 devi Balika 学校的20名高中生进行调查。通过课堂观察、问卷调查、学习者作业和作文的考察,搜集他们在汉语标点符号使用中的偏误。本论文中,笔者首先分别介绍汉语和僧伽罗语的标点符号分类和用法,其次将进一步对比汉、僧标点符号分类和用法的异同,进而分析斯里兰卡高中学习者的标点符号偏误情况,再分析大学生标点符号偏误情况,最后尝试对偏误产生的原因进行分析,并提出相应的教学建议。希望本论文能帮助斯里兰卡汉语学习者对标点符号学习有进一步了解,并帮助他们进一步提高对汉语标点符号的使用能力,避免出现更多偏误。
