Idea - barcode reader

[tonylampada]

Make a webpage that combines webcamjs with this gist (live demo here).

That would result in a useful tool :-)

I did it...

With my webcam, it doesn't work that great.
Any tips on how to improve it are appreciated :-)

Awesome work! Sorry I didn't have time to respond to this before. Seems like a natural use for the library. I'll take a look and see if there is anything I can improve -- I'd love for it to be able to handle QR codes too. Thanks for doing this!!

Thanks :-)
Unfortunately I don't know anything about image processing, but I think it should be possible to improve detection rate by doing something like:

In the canvas that shows the webcam image, display a horizontal red line, and instruct the user to align the barcode with it. Then the alghorithm that does the image processing would have a "better idea" of where to look for a barcode on the image. But I don't really know how much that would help :-)
