摘要
本文以长沙简牍博物馆所收藏的简牍文物为研究模型,对简牍文字的提取和修复进行了研究。提出了使用Canny边缘检测算子来提取文字的轮廓信息,然后再通过设置灰度阀值和人机交互相结合的方式对文字轮廓进行修复,最后再对文字轮廓进行填充,从而实现了简牍文字的提取与修复。试验表明,该方法对简牍图像的文字信息具有良好的修复效果。
Making the Jiandu relics from Changsha Jiandu museum as a model,this paper does researches on segmentation and repair of Jiandu s letter. And this paper presented that distill letter s outline firstly by Canny algorithm, and then united thresholding and man-machine conversation to repair the outline, and then filled the letter s outline, and finally achieved the segmentation and repair of Jiandu s letter. A large amount of experimentation show that the result of repairing on Jiandu s letter is effective .
