Hi, I am a programmer, I was tasked by my boss to write some barcode reading software from cell phone photos. I found a paper by Orazio Gallo and Roberto Manduchi titled:
"Reading 1-D Barcodes with Mobile Phones Using Deformable Templates".
IEEE Trans Pattern Anal Mach Intell. 2011 September ; 33(9): 1834-1843.
I graduated long time ago in 1994 and my math is kinda weak.
In section B:Barcode decoding, I could understand everything except the part about "the list of cells" on page 9, where it states:
"The list of cells {V sub k to the t}, as well as the integral of p(o,w) within each cell, can be computed offline and stored for online use."
I did not understand the math about this and the cost function, I was wondering if anyone knows of any online tutorial or free source code about this ??
I uploaded some free C# code on my GitHub to try to code this algorithm and the code is at this url:

I also uploaded the paper itself, it is attached to this.
Thanks for any help out there in cyberspace.
Hi, I would like to ask if you have figured out how to implement this procedure?
Hi Martin, sorry this was a year ago and i tried to read the paper but got stuck trying to understand some of the calculus and math and i could not implement it. I am sorry i wish i could have implemented it and understood the math then i would give you code and explanation and written up some hopefully easy to understand documentation on understanding the algorithm. Sorry , i hope you find better people than me that can help you.
