Thank you.
Hope it helps!


Is it possible to read license plates?
here in Brazil, the signs (image attached) have information about the city and state.
How can I not read this information?

Yes it can.

Please send me Beta version

You already have.
The one I sent you for Tamil text recognition and it didn't work due to Tamil not supported.

Oh, i think another new version with Tamil support also available.

Tamil is not supported unfortunately.
