摘要:: 甲骨拓片字形图像是直接来源于出土甲骨的甲骨文字形图像,是获取高质量甲骨文字形的重要途径之一.由于书写材料本身质地的原因以及受到污染和腐蚀,字形图像边缘锯齿形状明显,很多地方会有突起的毛刺,无法直接使用,需要对字形图像进行平滑复原处理.对此,提出了一种基于数学形态学的甲骨拓片字形图像复原方法.首先介绍了数学形态学的基本原理,分析了甲骨拓片字形的特点,并针对甲骨拓片字形的特点,运用数学形态学对字形图像进行一系列运算,在水平方向、竖直方向以及斜线方向分别对字形边缘进行基于数学形态学的平滑处理,在保留字体风格的同时对甲骨拓片字形图像边缘进行平滑.实验结果表明,该方法对甲骨拓片字形图像的复原是有效的.

Abstract:: The image of the character on Jiagu mbbings comes directly from the tortoise shell and animal bone excavated underground，and it is one of the important sources of high quality Jiagu font．Due to the quality of the writing martial itself，as well as the contamination and corrosion，the zigzag shape of the edge of the character image is obvious，and there will be raised buns in many places．Which canna he used directly，so it needs to be smoothed and restored．For this，we propose a restoration method of characters on Jiagu rubbingsbased on mathematical morphology．We give a brief introduction of mathematical morphology first．analyze the characteristics of Jiagu mbbings characters．The image of the character on Jiagu robbing is smoothed well with the style of the character preserved after a series of operations of mathematical morphology in the horizontal，vertical，and diagonal directions．The experiment shows that the proposed method is effective in restoration of Jiagu rubbings character image．
