Not quite sure what you expect to extract here? The barcode is just
an image, so what exactly would you expect the output of this program
to be?

If you need to decode the barcode, there are a couple of open-source
packages to do that. One that I have used is libdmtx (
http://www.libdmtx.org/ ).
It is in C, though there seems to be a Python wrapper for it:
