基于拓扑配准的甲骨文字形识别方法

Identification of Oracle-bone Script Fonts Based on Topological Registration

甲骨文字形具备较为稳定的拓扑结构特征,虽然异体字较多,但是同一字形的不同写法具有一定的拓扑稳定性,这使得从字形上区分不同的甲骨文字形成为可能。文章通过分析甲骨文字形的拓扑特征,研究甲骨文字形的拓扑顶点及拓扑顶点之间的拓扑关系,建立了拓扑顶点间拓扑关系的拓扑描述,将图画性质的甲骨文字形转化为拓扑图形,并对拓扑图形进行编码,实现了甲骨文字形拓扑结构的形式化描述。

Oracle-bone script, as the character system with stable topological structure, although has many variant forms,same characters share the semblable topological structure for different forms. This characteristic makes it possible to identify different fonts based on the forms. By analyzing the topological characteristic,topological vertexes,and the topological relation among topological vertexes, the research describes the topological relation among topological vertexes and converts oracle-bone script fonts to topological graphs. Meanwhile,by coding the topological graphs, the authors realize the formal description of topological frame.
