Location and Recognition of Free Tables in Form

In this paper we propose a method to locate and recognize free tables in forms. The method is based on the OCR recognition results of forms. The keywords of results such as NO., PRICE and so on are used to locate the table header. We combine the information of header and projection of table to get the column and row separators. Finally, all the information mentioned is used to extract and revise tabular data. At the end of this paper, we show and analyze the experimental results.
