Issue with some Barcodes (code_93 example)

[Eduardozv]

Hello,

First of all, thanks a lot for these improved and keep up to date version of the scanner! 👏

I'm using quagga for my project. But i'm having difficulties scanning these example barcode.
i tried on quagga demo app, and it doesn't work either.

These same barcode is scanned in other barcode reader program (https://websdk-barcode.scanbot.io/#/scanning) at a very high speed.
Example :

Testing it with a perfect generated barcode with that code is working well:

What could be the problem with these one?
Have you done any investigation regarding improving image quality preprocessing noise reduction filters or something like that ?

Would be really thankful

Hi there! Thanks for the sample. One of my goals for this, is to break it up into pieces so that it will work more like a pipeline, than an "all-in-one" piece, and then you can construct your pipeline with say a camera-image-grabber, a pre-processor, and a series of readers/decoders. Something like that. I am admittedly not much of an image recognition and manipulation guru, though, I'm just trying to keep the software current and enable myself and others to continue using it in new and improved ways.
