Using Long Lines for Forms Recognition

      Method for Forms Definition, Forms Recognition based on line
structure analysis, and a method for form verification and
registration are documented within the IBM Systems Journal, Vol. 29,
No.  3, in the article "Intelligent Forms Processing" by R. G. Casey
and D. R.  Ferguson.

      In the information currently disclosed within the IBM Systems
Journal, on page 439, there are three methods of forms recognition
described.  They are 1) form recognition based on a preprinted form
number; 2) form recognition based on matching line structures; and 3)
form recognition based on matching line structures and form text.

      This article continues to describe that Intelligent Forms
Processing (IFP) uses item 2 above, form recognition based on
matching line structures.  It describes the recording of each
instance of a form line and the storage of these form lines
(described within the application as a "form fingerprint") into a
Forms Library during forms definition.  It further describes
"matching" these form lines during forms processing to provide
automatic forms recognition based on the incoming form's line
structure.  Finally, it describes a method of forms "verification,"
which may be necessary to ensure that the incoming form is an exact
match of the selected form (incoming forms may be missing lines due
to poor scanning, photo copies, etc.) and to provide information on
form skew and form offset.  The method des...
