reading a barcode image in any orientation

[biswami]

Hi,
I am trying to read a barcode image using the image processing
toolbox in matlab.I am able to read a perfectly horizontal and ideal(ie less
noise elements) barcode image.However,that logic is totally useless if
it has any orientation other than horizontal.I have had quite a few
discussions on this and what people suggest that I may use 1 D wavelet
transform.Also,I seem to have seem some other implementations where
numerous diagonal lines cut the image and probably scan the black and
white pattern along those lines.Then there's mention of Hough
transform as well.I am quite at loss how to proceed.Can someone please
guide me towards some algorithm ....or some code snippet(either matlab
or any other language)...thanks in advance.
Regards,
Biswajit

Thanks Bassa,
I had looked at the first link sometime back.......i am yet to try out the second link...both of these are implemented by the same guy and have sent a mail to him for some help..
The 3rd link is actually a post by me in one of the newsgroups..am yet to decide how to work on the suggestions mentioned therein...
I guess someone might have done something similar using OpenCV....any inputs greatly appreciated..

New tech has come called QR code which can be read from any orientation
