摘要
提出了一种面向对象的表格图像版面分析方法,引入属性关系图的概念来描述表格版面结构,以表达表格组件间的复杂高维关系.属性关系图中属性的引入一方面可以描述组件的非结构特性,另一方面还可以利用属性来表达一些组件间的约束关系.该方法已应用于实际系统,测试结果表明该方法能够充分表达表格的结构化特点,同时具有相当的灵活性,为表格分析提供了一个实用的接口.
Document analysis of object-oriented table-form images was proposed. I he concept of attributed relational graphs was introduced to describe the structure of form layout, expressing the complex high-dimension relationship between the components of the form. The introduction of the attribution of the attributed relational graphs can describe the non-structural characteristics of the components, and express the constraint relationship between the components. The method has been applied to the actual system. The test result indicated that the technique can fully represent the structural features of form and be possessed of considerable flexibility, providing a practical interface for form document analysis.
