Abstract: According to the features of line intersection and the dependent relations between the name fields and data fields, the layout structure is classified into six classes, and then a definition of the Maximum Attributive Zone(MAZ) is presented. Based on the MAZ, an algorithm for the table-form image segmentation is presented. Not only can this method analyse the filled-in table-form images logical layout, but also it may divide the interdependent units into the same sub-tables according to the basic layout fragments. The experimental results show that this algorithm is effective.

Key words: line intersection features, base layout structure, table image segmentation
