barcode reader

barcode reader which does not use thresholding

Description

the main file is barCodeCam.m
this is definitely not the most robust barcode reader, but seems to work on low resolution barcode photos, with some amount of distortion.
some sample photos are included. i have not yet implemented the image segmentation to crop the text and surroundings out of the barcode. so users need to crop the barcode and feed it to the code.
i am sorry the code is quite messy. there can be some redundancies and a more compact version is possible.
your feedback will help me improve it.
the barcode symbology used is EAN-13. the variable G gives the array of barcode without the symbology.

• Required Products: Image Processing Toolbox
• MATLAB release: MATLAB 7.5 (R2007b)

I just tried the code. It works well for sample image Cam, but shows error in case on Cam3 and Cambook3. Also the EAN-13 barcode i downloaded from net is very different from the bar codes I see on things. I really need this code!! Please help!!!

hi haritha,

most probably it is because the cam.jpg file is not in the filepath/searchpath. Easy solution is to copy the file 'cam.jpg' into the same directory as the barcode_reader function or m-file.

while running the file im getting an error

File "cam.jpg" does not exist.

Error in ==> barcode_reader at 4
A0=imread('cam.jpg');
