Thus, if the maximal value differs from the minimal value, this allows more variations of barcodes
detection. However, this may slow down the recognition as the number of recognition attempts
The maximal allowable value of this option is 31 pixels. If the entered value is more than 31,
the component will reduce this value to 31 pixels.
This preprocessing option depends on the barcode Orientation
, which is specified on General
. If the orientation is not specified (i.e. Autodetect
is used), the component first makes
image preprocessing in assumption of horizontal orientation (Left to Right
or Right to Left
then - in assumption of vertical orientation (Down to Top
or Top to Down
). This doubles the
amount of recognition attempts and therefore slows down the recognition. Therefore it is
recommended to specify the Orientation
when you use this preprocessing option.
Dilate white pixels
The purpose of this preprocessing filter is to decrease by a specified amount of pixels or eliminate small
black objects. This may be useful when the barcodes have textured background. For example, this takes
place if the colored image was converted to the black and white.
Enter minimum and maximum amounts of pixels by which the component will decrease each black
object on the image (like bar) to horizontal and vertical directions. You can use RRT in these fields.
If the maximum value differs from the minimum value, the component tries to recognize barcodes in
several attempts, for every value from the specified interval. For example, if the minimum value is 1 and
the maximum value is 3, at the first attempt the component decreases each black object on the image
by 1 black pixel , at the second attempt - by 2 black pixels, and finally, at the third attempt- by 3 black
pixels. The default value is 0 for both values - this means that this preprocessing filter is not used by
default. Thus, if the maximum value differs from the minimum value, this allows more variations of
barcodes detection. However, this may slow down the recognition as the number of recognition
The picture below illustrates several steps of this preprocessing method:
