Abstract

A method is disclosed to automatically calculate the location of a fail-to-find window prior to or during runtime of an image processing application such that the fail-to-find window is centered on the center point of the original search window and encompasses and area somewhat larger than search window. The fail-to-find window is used to cut out a portion of an image for exception processing activity which occurs when an application searches an area specified by a search window but fails to find the data to be processed.

Location of Fail-to-Find Window after Image Processing

      A method is disclosed to automatically calculate the location
of a fail-to-find window prior to or during runtime of an image
processing application such that the fail-to-find window is centered
on the center point of the original search window and encompasses and
area somewhat larger than search window.  The fail-to-find window is
used to cut out a portion of an image for exception processing
activity which occurs when an application searches an area specified
by a search window but fails to find the data to be processed.

      Some image processing applications conduct processing
operations upon a limited area of the digitized image defined prior
to the runtime of the application.  An example is shown in the Figure
character recognition application.  An area defined by search window
(2) is specified for image (1) which provides boundaries for the
application to search for a string of characters to recognize.

      If the recognition processing algorithm cannot find the data
string within the search window, a larger fail-to-find window (3) is
returned to the application for reconciliation by another application
or by an operator.

      The center of the fail-to-find window is located on the center
of the search window.  The specifications of the predefined search
window are used in a program to automatically calculate the center of
the fail-to-find window prior to runtime of the image processing
application.  Once the center point is located, the edges are placed
by the program according to the horizontal and vertical fail-to-find
window size which is provided by the the user.

      In cases where the search window is close to a document edge,
the calculated position will cause a portion of the fai...
