摘要:
本文提出了一种复杂表格识别和处理方法。该方法首先输入一张未填有用信息的空表格作背景信息表格,然后输入已填有用信息的同类表格作有用信息表格。对有用信息表格图象采用几何位置配准使两幅表格的背景信息重合,然后利用数字逻辑运算和智能相关处理技术以达到对残留背景信息的彻底清除,保留后填入的有用信息供识别处理。此方法对表格形式不限,适用于背景信息和有用信息采用同色或异色笔填写。方法仅需第一次输入一张空表格后,就可连续处理同类型表格。文中给出了表格处理结果。
Abstract:
A recognition and processing method of document form background information is presented. First, an original form, called Background Information Form Image (BIF1), is scanned. The same kind of forms, which is filled by various characters that one wants to recognize and process, called Useful Information Form Image (UIF1), is stored. Then, a geometric remedy of UIFI is used for the best matching with the BIFI. A digital logical operation is carried out in order to erase the most of background information and an intelligent correlation technique is available to completely delete the remained background information. This method is suitable for processing various forms, including background and useful information printed or filled with same colour. It can continuously process same kind of UIFIs with the input of BIFI only once. The document forms are shown and satisfactory results are obtained.
