Query: A symbol-based algorithm for decoding bar codes   We investigate the problem of decoding a bar code from a signal measured with
a hand-held laser-based scanner. Rather than formulating the inverse problem as
one of binary image reconstruction, we instead incorporate the symbology of the
bar code into the reconstruction algorithm directly, and search for a sparse
representation of the UPC bar code with respect to this known dictionary. Our
approach significantly reduces the degrees of freedom in the problem, allowing
for accurate reconstruction that is robust to noise and unknown parameters in
the scanning device. We propose a greedy reconstruction algorithm and provide
robust reconstruction guarantees. Numerical examples illustrate the
insensitivity of our symbology-based reconstruction to both imprecise model
parameters and noise on the scanned measurements.
