The research of the character image pre-processing focuses on the gray-scale image filtering algorithm, the skew detection of image and character segmentation algorithm; 在字符图像预处理方面,重点研究了灰度图像滤波算法、图像的倾斜检测和字符分割算法;
First of all, using the theory of general states Markov chain, we define some character number of skew product Markov chain. 利用一般马氏链的理论,首先给出了绕积马氏链的特征数的定义和相互关系。
During document scanning, the skew of input document images is inevitable. But the algorithms for layout analysis and character recognition are very sensitive to page skew. So skew detection and correction is an important step during preprocessing of document analysis. 在文档扫描过程中,输入的文档图像不可避免地会发生倾斜现象,而布局分析及字符识别算法对页面倾斜都十分敏感,因此倾斜检测和校正是文档分析预处理的重要环节。
