Multiline license plate

[zhouhao27]

Assume I have training data for single line license plate. The OCR result is quite accurate. I want to extend it for multiline license plate. Have a few questions:

1. Because the fonts used for single/multi line license plates are exactly the same. So I think I don't need to do the training. Am I right?
2. I should do the configuration for multiline license plate. Is there any guide for this?
3. Can I use two separated configuration files at the same time? How?

Any idea? Thanks.
