Barcode scanner detected wrong barcode sometimes about mlkit

[baversjo]

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/

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:
