Scan
have a dramatic effect on the level of
human intervention required after the initial
scan has taken place. For that reason, we
have standardized on ABBYY, a well-
respected leading OCR software
developer.
Our tests are run using the latest level of
ABBYY FineReader 8.0 software running
in default modes. Through fine tuning of
the rich feature set in ABBYY FineReader
8.0, an additional portion of the manual
intervention could be removed. However,
to maintain benchmark comparison
procedures, default settings were selected.
200 dpi vs. 300 dpi Output
The graph below clearly illustrates the
advantage in terms of reduced user
intervention when scanning for OCR
workflow is switched from 200dpi to
300dpi.
The increase in bandwidth and the slight
additional delay before the larger 300dpi
scanned file can be accessed by the
desktop operator are more than offset by
the greater accuracy of character
recognition.
Text vs. Text/Photo
There was also a clear differentiation
between the recognition of text and
text/photo scanning modes. While the
algorithm used in text/photo mode may
result in better looking output of images
and photographs, it resulted in less clear
character capture which again results in
increased user intervention rates. Users
should look carefully at the types of
document they are scanning before
choosing the scanning method.
