How to decode a barcode from an image file?

[kimymiky]

Does anybody know how to decode a barcode from an image file? I have studied image processing so far, but I still cannot come up with a good method to do it. I am particulary interested in decoding postnet, code 39 and pdf417. Thanks.

Not sure I follow what you are doing.
Do you have a bar-coded image you want to scan?
Or are you trying to make a barcode image file like a bitmap or jpeg?

I have image files which have barcodes as images. My goal is from barcodes as images ----> decode it. I am not trying to generate barcodes into image files. The barcode is already given in image files. Thanks.

I think you should try here:

http://www.pegasustools.com

They've got some stuff to do what I think you want. There's a demo package in which you select a tif to open, hit analyse, and it decodes all the barcodes on the page. It handles multiple barcode types on the same page, and is good for noisy scans, where the quality is poor or the codes are skewed.

I use this for testing, when I don't have a barccode sacnner to test a printed code: scan as a tif on my desktop scanner, then analyse in Pegasus.

Jim,
Checked out the Pegasus site, but I wasn't sure which development tool or product prcesses images to recognize barcodes. What's the name of the tool or demo? Thanks,
Mike

Do you already own a scanner ?
You need an image scanner like for example the Dolphin 7200 2D from HHP.
