Abstract
Barcode decoding bypassing binarization is provided which relies on deformable templates to makes use of all the gray level information of each pixel in the barcode image. Parameterization of the deformable templates allow for efficiently performing maximum likelihood estimation independently on each barcode digit and enforcing spatial coherence across the barcode digits.
