【摘要】 提出了一种图像背景下的满文文字提取方法。用数字图像处理的方法对含有图像背景的满文图片进行单字提取,并进行去噪、细化、剪枝等预处理,找到这个单字的主轴,终止点、内部点和交叉点,在主轴上找到临界点,由临界点进行笔画生长从而达到满文文字笔画提取的目的。为了验证方法的可行性,对手写体满文图像、印刷体满文图像和彩色图像中的满文分别进行了文字提取。实验结果表明该方法对满文文字提取率较高,为进一步研究满文的识别奠定了坚实的基础。更多还原

【Abstract】 Based on the structure and characteristic of Manchu,this paper elaborates a new stroke extraction method. Firstly,the digital image processing method is used to extract the Manchu character from an image background picture,perform such preprocessing methods as de- noising,thinning,pruning and so on. Then the mid- axis of Manchu character,termination point,interior points and intersection points are found. Moreover,the critical point on the mid- axis is achieved. The critical point by using the stroke growth algorithm is used to separate the stroke so as to achieve the purpose of Manchu text stroke extraction. To verify the feasibility of the method,this paper carries out a text extraction on handwritten Manchu,printed Manchu and Manchu in the color image. Simulation results show that the method is effective in separating the Manchu stroke and will lay a solid foundation for the further study of Manchu identification.更多还原
