When trying to detect this Interleaved 2of5 barcode, which has no quiet zones in the image

I get the correct result 3012627384 using [1].

When trying to scan this barcode with a camera and moving the camera from left to right, wrong results are produced, which have truncated the the last digit pairs, eg. 301262 or 30126273.

The reason for this seems to be, that the shape of the stop code itself is occurring in the barcode and the stop-code is only distinguishable if there is a quite zone after it, which seems to be assumed if there is the right image border instead of a real quiet zone/white space.

Is there a way to enforce real quiet zone to be enforced?
