MRZ incorrect recognition

Issue:

A document with MRZ can't be recognized or MRZ recognized not properly.

Solution:

If you are using Document Reader SDK version 6.2 and above, to improve MRZ recognition you can process image with parameter:

{"mrzDetectMode" : 1}

You can test it here, by putting a string as shown on the screenshot  below to Custom parameters field.

If the image is of extremely poor quality or has an excessively motley background, you can try using parameter:

{"mrzDetectMode" : 2}
