Character Separation
Characters are considered separate characters if the distance between the
correlation boxes is equal to or greater than
1 /
2
the width of the Character
spacing box. If the distance between the correlation boxes of two characters
is less than 1/2 the width of the character spacing box, the OCR Tool will
treat the two characters as a single ”confusion character” and in most cases
the tool will fail.
Character

separate characters.

When the distance between two printed characters is greater than the
Character Spacing plus 1/2 the Space Dimension, a space is inserted into the
read string.

window boundary respectively is greater than the Character Spacing plus 1/2
the Space Dimension, a space is inserted before or after the read string.
