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.

MRZ_detect_mode.png

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

{"mrzDetectMode" : 2}
