Some of the most commonly used parameters in the OCVFontless Tool
are:
•
Apply Automatic Min Sharpness — When enabled, verifies that the
inspected characters are clear and in focus. By default, the tolerance
for this inspection is determined to be 65% of the trained character.
•
Apply Automatic Min Contrast — When enabled, verifies that the
inspected characters have the proper contrast. When disabled, the
OCVFontless Tool will still pass even if the characters are very dark.
By default, the tolerance for this inspection is determined to be 50%
of the trained character.
•
Group Final Res Limit — The primary setting for the OCVFontless
Tool. When this is set higher, it allows the characters to have more
variation from the trained characters and still pass the inspection. You
must click Apply Symbol Group Settings before these changes are
made to the previously trained symbols. This button is located at the
bottom of the properties page.
