Best Java Barcode reader library?
452196Jan 12 2012 — edited Sep 13 2012I'm looking to read barcodes from scanned documents. The idea is to create marker pages to be inserted in stacks of pages for scanning, classifying the document type etc., so that the documents can be stored in the right places.
The most visible library for barcode scanning on the Internet seems to be "zxing" (Zebra Crossing) on Google. I've been experimenting with this but, thus far, detection rates seem pretty disappointing.
What have people's experiences with this stuff been like? Are there more dependable libraries out there?
(Later)
I've found out what makes zxing unreliable - it's the behaviour of our scanner which produces a halo of dithered gray arround the black areas on the paper. This is sure to mess up edge detection. Doing a blur operation on the image, or tellling the scanner to return the image embeded in an PDF gets arround it.
