System for creating a document information database

摘要

In a system for producing a database of document information, sample documents (12) are scanned in a scanner (14) connected to a personal computer (16), and digital images of the scanned documents are stored. The digital images are displayed in turn as visual images (140) on the screen (142) of the computer display unit (24), and using a mouse (26), box-shaped areas (146) are produced on the screen and manipulated and sized to define zones, the locations of which are stored in a document definition file. An identification feature file may be formed by analyzing the stored digital images to determine graphical features thereof such as straight lines. The zones may be verified in a verification procedure wherein documents are again fed into the scanner (14).
