摘要

给出了完整文档识别系统的一部分表图像分割算法。该方法引入了表网格的概念，为表结构分析提供了先进的方法。它为表提供了一层终端符号，供语法方法使用。详细讨论了通过分析连通构件投影轮廓来实现网格检测的方法。表结构分析的简单规则涵盖了大多数实际生活表。该系统已经实现，并且现在广泛应用于FineReader OCR产品中。

Table image segmentation

Algorithm for table image segmentation, a part of complete document recognition system is presented. The proposed approach introduces a concept of table grid which can serve for advanced methods of table structure analysis. It provides a layer of terminal symbols for the table, which is used by syntactical methods. Detailed discussion of grid detection is presented which is performed through the analysis of connected components projection profile. Simple rules for analysis of table structure cover majority of real life tables. The system is implemented, rested, and is now extensively used in FineReader OCR product.
