PROBLEMS
This section contains information and solutions for possible OCR
problems. First we provide suggestions for improving recognition
accuracy, second on getting good results from fax input and finally on
system or performance problems arising during OCR.
Text does not get recognized properly
Try these solutions if any part of the original document is not converted
to text properly during OCR:
u
Look at the original page image and ensure that all text areas are
enclosed by text zones. If an area is not enclosed by a zone, it is
generally ignored during OCR. See the section on creating and
modifying zones, Working with zones, in chapter 3.
u
Make sure text zones are identified correctly. Reidentify zone
types and contents, if necessary, and perform OCR on the
document again. See Zone properties in chapter 3.
u
Be sure you do not have an unsuitable template loaded by
mistake. If zone borders cut through text, recognition is
impaired.
u
Adjust the brightness and contrast sliders in the Scanner panel of
the Options dialog box. You may need to experiment with
different settings combinations to get the desired results.
u
Check the resolution of the original image. Hover the cursor over
the Original Image area for a popup display. If the resolution is
significantly above or below 300 dpi, recognition is likely to
suffer.
u
Make sure the correct document languages are selected in the
OCR panel of the Options dialog box. Only languages included
in the document should be selected.
u
If you use True Page as the Text Editor view or for export,
recognized text is put into frames (formatting boxes). Some text
may be hidden if a frame is too small. To view the text, place the
cursor in the text frame and use the arrow keys on your keyboard
to scroll to the top, bottom, left, or right of the frame.
