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.
