中文摘要：

在大篇幅的手写维吾尔文文本图像中,往往会出现粘连字符这一现象。这一现象会对文本行分析和笔迹鉴别等研究工作造成影响,同时所处环境为大篇幅手写图像,在对粘连字符切分时会受到其余非粘连字符的较大干扰。针对上述问题,本文提出了对手写文本图像定位线的正确提取方案,以连通域特性为基础,通过定位线与文本图像融合,使行间粘连字符所在文本行为同一连通域想法,可自动提取出粘连文本行,再根据粘连字符所占宽度和高度大于非粘连字符,从而自动提取出粘连字符。对提取出的粘连字符通过定位线可确定出粘连区域,对粘连点所处位置进行统计分析后在该位置处添加一条与背景同色细线从而达到分割效果,最后对分割后的粘连文本行通过着色方法逐行提取。实验表明,上述问题通过我们的方法得到了很好的解决。在实验结果分析中,本文给出了每个算法的性能指标数据,并与其它文献进行了对比分析,论证了本文研究方法的可行性及存在的一些主要问题。

英文摘要：

In sensitive word extracting,handwriting recognizing and other text analysis of images of large handwritten Uyghur texts,the connected characters need to be segmented as a result of a phenomenon of free-format handwritten Uyghur characters,which,affect text analysis,handwritten recognition and other researches.However,in major methods of recognition and segmentation of connected characters,extraction and segmentation of large handwritten Uygur text images prove difficult without compromising writing rules.A method is presented in this paper on resolving the above-mentioned issues.First of all,approaches to positioning line which can be all draw out without any mistakes.Then,the connected text lines can be automatically extracted by the fusion image of positioning line and text image on the basis of connection area.After that,text lines can been automatically extracted based on the fact that the width and height of connected handwritten Uyghur characters are greater than unconnected handwritten characters.Third,the touching area of handwritten Uyghur connected characters can be positioned by the fusion image of positioning line and handwritten Uyghur connected characters,because positioning line and handwritten Uyghur characters fuse together so that the touching area is adjacent to positioning lines between them.The connected point is located by analyzing touching area of handwritten Uyghur connected characters.A line is added to the connected point location.According to the above method,the line of the same color must be exactly the same background of text images.Finally,we can extract the text line of handwritten Uyghur connected characters by the method of coloring.Regarding handwritten Uyghur text images of the handwritten Uyghur text images,experiments show that above problem have been well solved.In the analysis of experimental result,the feasibility of the research method of the thesis is proved by analysis performance index of each algorithm and compared with other literatures but there are still a lot is
