Operation
OCR
OCR: Specifies whether OCR font recognition is deactivated
■
(deactivated) or activated, whereby the detection of normally printed font
(dark font, light background), inversely printed fonts (light font, dark font
background) or both types (normal & inverse) can be activated
simultaneously.
Text flow direction:Specifies the direction in which the OCR code should
■
be read. For example, it is necessary to indicate whether the character
string HOHOHO on a OCR code should be read from right to left or from left
to right.
Individual line: Specifies whether an individual line for placing a template
■
is output if there are other characters immediately above or below it.
Remove checksum: You have the option of removing a read checksum
■
before the decoded OCR code is output. The output code no longer
contains the checksum as a result.
Inhomogeneous background: You can select this field to enhance OCR
■
recognition. This field is recommended if you have selected the pass
template. Many countries print a pattern behind the OCR code on the ID,
which prevents the code from being read properly. However, the processing
time increases when the field is selected.
Output ambiguous characters: This function only influences OCR output
■
when the pass template is selected.
Disable '.' characters: Suppresses the detection/output of '.' characters
■
(e.g., decimal point, end of sentence). '.' characters that form part of a user
template are ignored.
Ignore pass checksums: You also have the option of reading identity
■
cards, visas, and passports that do not meet ICAO checksum standards. If
the function is deactivated and the ID does not meet ICAO standards, no
results are generated.
Templates: You have the option of choosing from a selection of existing
■
templates.
User template:Selecting the "User-defined" field under "Templates" allows
■
you to compile your own template. A table is displayed if the mouse pointer
remains over one of the two input fields for more than 1 second. The table
contains placeholders that can be inserted manually or by clicking the
mouse.
