User Interface for Multi-Entry Forms

      Disclosed is a user interface system for a forms-processing
Optical Character Reader (OCR) system.  The objective of the system
is to supply uniform user interface for checking results of the OCR
process, even if the forms have different layouts.

      The OCR system scans a form document and captures the
image.  Then, the system analyzes a layout; detects a table; extracts
information on columns, rows, and cells in it; and recognizes
characters in the cells.

      The user interface system receives results of the layout
analysis and recognition.  It identifies a format of the target form
by comparing pre-captured information on various formats.  It
extracts each cell on the original image and associates them with
recognition results.

      For an operator of the system to check results of character
recognition, it is very helpful to display both recognition results
and corresponding images in a uniform format.  This user interface
utilizes information that is captured by form identification and
displays results in a uniform format even if scanned forms have
different layouts.

      The Figure shows an example of the process.  Form 1 and Form 2
are sample images of form documents which have different layouts.
The system analyzes their images and identifies each format, detects
cells, and recognizes characters.  The user interface system displays
both forms  in a uniform format, shown in the middle of...
