Barcode recoginization failed with Low quality Images about js-zxing-pdf417 HOT 8 OPEN

It is a known issue. More work is needed to get the library to with lower quality images. We have tried a few different approaches of pre-processing but none fair better than what we have here. I am still confident there is a workable model here we just need more time to get to it. We will take a look again, maybe middle of next year (were focused on other projects at the time). Pull requests accepted ;)

The core issue in our tests has been lack of focus on getUserMedia - https://code.google.com/p/chromium/issues/detail?id=343894

One approach we have not tried that I think has promise is capturing via video and doing frame averaging to sharpen the picture trying candidates along the way.

We should look at some of the techniques applied here http://www.windytan.com/2016/02/barcode-recovery-using-priori.html and see if we can improve results at all.
