Remarks

You specify the Confusion(CogOCFontModel, CogOCFontModel) (in the range 0.0 through 1.0) to tell the tool the confusion score above which two characters are to be treated as potentially confusing.

As you decrease the confusion threshold, the OCV tool compares more characters with the expected character. As you increase the confusion threshold, the tool compares fewer characters.

Default Value: 0.5
