Answer 1

I think it's kind of expected. Due to the bias of image quality and barcode position, it's possible that part of the real barcode image is also identified as a barcode from the perspective of barcode detector.

Answer 2

There really is nothing you can do about that, it just depends on the image/frame given to the analyzer. There are many factors that can effect the scanning of the barcode like light, angle of image/frame, image quality of the barcode, or quality of the barcode itself that can cause duplication to be found.

You will just need to have a way to remove ones that you dont want
