摘要
古文献版本差异性研究是古文学研究的重要方向之一.根据古文献文字图像的特点,在文字切分的基础上提出了古文献差异性比对的方法.首先对手写汉字进行归一化处理;然后采用小波变换、距离计算、波峰分析进行特征向量的提取;其次根据特征向量计算汉字的异同;最后采用基于滑动窗口的方法对两副图像进行比对,并在原文字图像中标记出内容不同的位置.实验结果表明,提出的方法能够很好地应用于文字图像差异性比对.
Version otherness study of ancient literature is one of the most important directions of ancient literature research. According to the characteristics of character images taken from ancient literatures, an ancient literature otherness comparison method is proposed based on the text segmentation. Firstly, the handwritten Chinese characters are normalized, then the feature vector extraction is obtained by using wavelet transform, distaace calculation and peak analysis. After that, the differences and similarities between Chinese characters are calculated according to the feature vector. Finally,two images are compared by adopting a method based on the sliding window and the locations are marked in the original text image where the contents of two images are different. Experiment results show that the proposed method can be well applied to the other- hess comparison of character images.
