Add books, DVD, CDs from barcode image

Filed under: Uncategorized — gurulib @ 12:13 pm

From the day we launched GuruLib in June 2006, we were diligently working on various image processing algorithms for extracting UPC/ISBN code from a barcode image. We have the feature finally working. Below is a test UPC barcode that I captured using my cellphone.

UPC barcode image

You can upload either individual barcode images in either JPG or GIF format or you could first zip a group of barcode images and then upload the zip file. GuruLib will add the images to the image decoding queue and will start decoding them when the decoding engine becomes available. Since the technology is in its early stages, feel free to leave comments on improving the user experience.

Tip for capturing a good barcode image

  1. Make sure there is enough ambient lighting.
  2. Make sure the captured image is not blurry.
  3. Make sure the lines on the barcode are clearly visible.


  1. Where do you go for help here? I couldn’t find an email or any help section, so I figured here was better than nothing…

    Is there no way to hide your library/profile/all information from other users? Why does my location automatically pop up? Where do I go to delete my account if in fact there is no way to keep your library (and username, and location) private?

  2. Very, very nice feature !
    I can’t see what’s missing yet, but sure you’ll find !
    To my mind, the graphic design could be improved, but the essentials are here.

    Nice job, as usual !

  3. A new feature has been added in your settings that will allow keeping profiles private. Let me know if that works.
