Hi ngân,

I tweaked your config file and was able to get it to recognize.  After doing that, I noticed there's a bug in the multi-line postprocess code.  The results are completely wrong without fixing that issue.  I made some code fixes which seems to resolve the problem.  I'll need to do more testing before committing.  Here's images showing results for the two plates I tested.

Do I have your permission to include your plate detector in the OpenALPR open source library?  If so, can you upload your plate images and crops or metadata?  That would be very helpful for improving the software for other folks in Vietnam.

Android uses the same code as the main project.  It's just that it needs to be compiled via NDK.
