文档图像屏幕适配方法中的行切问题研究

摘要

针对当前使用嵌入式设备阅读文档图像时存在的不便,提出一种基于图像处理的文档适配的方法.该方法以数字图像处理技术为核心,根据设备屏幕尺寸对采集的文档图像进行切割重排,达到适应屏幕大小的目的.对于汉字结构带来的分割误差问题进行重点研究和分析,提出基于前后检测的方法以解决该问题.最后通过实例对该方法进行验证与分析,证明该方法具有一定可行性,并在切割文字的正确率方面有较好表现.%According to the inconvenience in reading document images with embedded devices, in this paper we present an image processing-based method of adapting document to screen. The method, regarding digital image processing technology as its core, cuts and rearranges the document images grabbed based on the screen size of the device to achieve the purpose of adapting to the screen size. In the paper we make emphasised study and analyses on the cutting error problem in regard to the structure of Chinese characters, and propose a method based on pre- and post-detection to solve it. Finally, through the examples the method has been validated and analysed. The method is proved to be feasible to certain extent and has a preferable performance in accuracy rate of text cutting.
