We are using the Java SDK example for recognition with "textField" parameter, and supplying the letterSet as "0123456789". It recognizes all the other numbers properly, but confuses the "3" to either "X", or "I", or some special characters every time.

Is there a way to force the SDK to recognize only numbers. e.g. instead of identifying it as "X", it can make a best effort to recognize it as a number. i.e. "3" or even "6" ?

To recognize only digits it is recommended to set special language, "Digits". See list of all available languages here.

Another hint is to change size and resolution of the image so that letters height is ~ 100 pixels @ 300 dpi
