To find the location of barcode, normally differences of gradient method is taken. If we take contrast gradient across a barcode, we get high gradient in horizontal direction while low gradient in vertical direction. So where their difference (ie horizontal gradient-vertical gradient) is maximum, we take position of barcode.

Please refer to these paper: Reading Barcodes
