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.
