Abstract

This paper discusses the processing of faxed documents. An example of the type of documents we are concerned with are order entry forms. The system is designed to receive order forms via fax, identify the form, extract the appropriate data and present the data to a host computer. The types of data recognized are hand printed characters, machine printed characters, and marksense fields. The system is model based. A model of each is created once from the original image and stored in a form model data base. The processing of the form consists of four steps: object extraction, form identification, form registration, data extraction (including character recognition). Once all of the data has been extracted it is sent for post processing where the data is corrected for errors in the recognition phase with respect to contextual dependencies, logistics, and application specific dictionaries and then to the host computer where the order is confirmed. Presently the system is implemented in C++ under OS/2 and is in commercial use.
