in reply to Barcode Recognition

A little more information would be helpful.

Are all the barcodes the same encoding?
Are all of the images the same direction?
What is the file type used to store the grayscale image?
Are all of the files of the same type (.jpg, tiff, png etc?)
Are the images clear / consistant between light and dark?

Are the original paper copies still in existance?
How many (approx) of these bar codes do you have? (hundreds, thousands, millions?

Enjoy!

    All barcodes are EAN-13, they are not the same direction, random angle some of them also upside down. They are all stored in PNG and TIFF (mostly 8bit) files. The images are not the same lightness, some of them are darker, also some of them are noisier. Some of them are not entirely focused - the scanning perhaps was not done right. I am talking of thousands of images.
