Abstract
This invention relates to the field of optical character recognition for data in drop-out forms. In the absence of permanent, fixed landmarks, this invention uses the structure of the entered data to provide a landmark to be used in solving various problems encountered in automated processing of drop-out forms. An expected data pattern is located in a scanned image and compared to a defined data pattern in a template form that serves as a reference.
