Parse MRZ

[chetan chaudahri]

Can you please help me to parse passport MRZ info.

We check the following documentation for parsing but didn't understand. in the document their mention to find type of document from the line but from line how we get front 

const MRZ_DOCUMENT_TYPE type = (lines.size() == 3 && lines.front().size() == 30) ?  MRZ_DOCUMENT_TYPE_TD1 : ((lines.front().size() == 44 && lines.size() == 2) ? (lines.front()[0] == 'P' ? MRZ_DOCUMENT_TYPE_TD3 : MRZ_DOCUMENT_TYPE_MRVA) : ((lines.front().size() == 36 && lines.size() == 2) ?  (lines.front()[0] == 'V' ? MRZ_DOCUMENT_TYPE_MRVB : MRZ_DOCUMENT_TYPE_TD2) : MRZ_DOCUMENT_TYPE_UNKNOWN));

The MRZ parser is 100% open source and hosted at https://github.com/DoubangoTelecom/ultimateMRZ-SDK/tree/master/samples/c%2B%2B/parser

Explaining the next code to you is useless because we use regular expressions (https://github.com/DoubangoTelecom/ultimateMRZ-SDK/blob/master/samples/c%2B%2B/mrz_parser.h) and they will fail because the returned result contains invalid characters. The invalid characters (‘*’) are returned because you’re using a trial version.
