Would you mind clarifying what you mean by MRZ text?

Note that the Text Recognition API only supports languages that use Latin characters. See our site for details:

Hello.Does this library read MRZ lines? I am also interested in reading MRZ lines

pchx-zz commented 7 years ago

The Text API isn't specifically optimized for reading MRZ text, but is certainly capable of reading any Latin text (though it may be less accurate in those cases).

Can anyone suggest a better option to read MRZ, text api is not helping out with MRZ.

Try OCRB.traineddata. Usage: tesseract input.jpg output.txt -l OCRB

parulsngh commented 5 years ago

Have tried the tess-two, its working fine but some time it suddenly stops reading text from image and again starts reading by its own. Didn't figured out the reason for same.

ajinkya933 commented 5 years ago

Tesseract needs proper input image try changing the image input by applying morphological transforms/ text localization algorithms and then run it through tesseract
