Off - line handwritten character recognition is one kind of pattern recognition technique . it involves the technologies of pattern recognition , digital image processing , digital signal processing , artificial intelligence and so on . it is widely used hi information processing , office automatic , machine translation 脱机手写体字符识别是模式识别的一个重要分支,它涉及模式识别、图像处理、数字信号处理、人工智能、模糊数学、信息论、计算机等学科,是一门综合性技术,在信息处理、办公自动化、机器翻译、人工智能等高技术领域,都有着重要的实用价值和理论意义。
Research on off - line handwritten character recognition has great worth . the information of off - line handwritten character is very scarce ( only 2d pixel matrix ) , and the handwritten characters have so many classes , complex strokes and shape distortion . all of above have become the obstacle of character recognition 由于在脱机手写体字符识别中,处理的仅是二维的字符点阵图像,而且存在字符类别多、字形结构复杂、手写字符的变形很大等问题,目前脱机手写字符识别技术还很不成熟,仍处于实验室研究阶段。
The problem of chinese handwritten character recognition by computer is thought of one of the most difficult problems in the field of pattern recognition . in our project of " computer chinese handwriting identification " and " chinese handwriting sort in internet " , we always need to pick some special hand script from the manuscript for discrimination . but this work is very troublesome , uninteresting and easy to make mistakes 在我们所从事的《计算机笔迹鉴别》和《网络化笔迹检索》项目的研究与应用中,经常需要从选定文稿中挑选出常见字以备鉴定,然而,从大段的手写文稿中挑选出所需要的字迹是一件繁琐的事情,工作量大、容易出错。
