The
Binarization Threshold
is the level beyond
which
binarization
is considered
unsafe
. The
lower this level is set, the more important smaller details will become and the faster the switch from
bitonal to the desired alternate image type (
see far above
) will happen.
Use the
Margins
screen
to define the image area
considered by internal de-
tection mechanisms. If, for
example, you needed to
exclude colored company
logos at the top of docu-
ments, you would increase
the margin setting for the
top edge.
4.6.2.5.5. Blank Page Detection
The function
Blank Page Detection
allows to
identify and discard or mark the images without
content, based on a multi-stage analysis and is configured with the following four settings pages:
The
General
settings page
contains just one control:
The
Copy to Back
option
(
visible when editing front
side settings
) and the
Same
as Front
option (
visible
when editing back side settings
) will duplicate and apply all settings made on one side, to the other.
Threshold
: Use the two sli-
ders for
Mark Threshold
and
Remove Threshold
to
set these values, as desi-
red. Please note that the
threshold value for mar-
king blank pages may ne-
ver be smaller than the threshold value for blank page removal. If immediate blank page deletion is
generally undesired, please set
Remove Threshold
to 0.
Sensitivity
: Use the sli-
der for
Sensitivity Level
to increase or reduce the
overall blank page detec-
tion sensitivity.
Activating the
Area Dependency
option will put the amount of data detected on an image in relation
to the total size of that image. Deactivating this option will cause blank page detection to operate
using the absolute amount of data detected, without consideration of image size.
