Registration and region extraction of data from forms
S.L. Taylor, Richard Fritzson · 2003
The widespread use of printed forms for data acquisition makes the ability to automatically read and analyze their contents desirable. The components of a forms analysis system include conversion from paper to an image through scanning, image enhancement, document identification, data extraction, and data interpretation. This paper describes techniques for manipulating form electronic images in preparation for data interpretation. A combination feature extraction/model-based approach is used for forms registration and field extraction. The system is demonstrated on United States Internal Revenue Service forms.>
