Extraction of filled-in data from colour forms

Abstract

The paper describes an intelligent system for extraction filled-in data from colour conventional forms. Filled-in characters in these forms can touch or cross the form frames. The empty form description is acquired in this system by interactive learning followed by automatic processing and extraction filled-in data from input forms. Some steps of input form processing (form coding and form dropout) are carried out for any input form and other (form registration and broken characters reconstruction) are needed if the colour of the user filled-in data coincides with the colour of the empty form only. Experimental results showing the performance of the system are described.
