I wonder if it's as simple as the algorithm is not checking the check digit in code128?

We're also having the same issue as @longld103.

The above barcode is sometimes pickedup as 2016101151D (correct) but sometimes as 2016022851/

Hi, have similar issue. Added comment to this issue #32 and to the tracker https://issuetracker.google.com/u/1/issues/159876630

We're having a similar problem with wrong detection, especially if the barcodes are a bit blurry.

The following image contains an EAN-13 code ("4014531682860"), but sometimes we get completely different EAN-8 codes (e.g. "12544059" or "12541249") as a result:

Blurry barcode

Other scanners (e.g. Google Lens) get a perfect detection, even though the quality is bad. If we use a sharp image, everything works fine:

I have the version com.google.mlkit:barcode-scanning:16.0.2 and the same problem happens

I am also getting wrong barcode detection when it's EAN-13

The actual barcode : 9100000013510
and it has detected : 2455340606005
