Detect Machine Readable Zones (MRZ) in images of identity documents

mrz-detection

Run scripts

The best way to test the run scripts is to create a data directory in the root of this repo and put the images in sub-directories of data.

getMrz

node run/getMrz.js --dir data/imageDir

This script will treat all PNG or JPEG images in the specified dir and create an out sub-directory containing the images at each step of the process. The purpose of this script is to locate the MRZ and crop/rotate the image to keep only this part.

Final images will be in data/imageDir/out/cropped

readMrz

node run/readMrz.js --dir data/imageDir/out/cropped --reference data/imageDir/ground.csv

This script will attempt to read the MRZ of all images in the specified dir and compare the read data with the reference.

The reference should be a CSV file with the following format:

image-name,MRZ-LINE-1,MRZ-LINE-2,MRZ-LINE-3

• image-name is the filename of the original image without extension
• MRZ-LINE-x are each line of the MRZ (two or three lines)
