Claim 5:
6. A non-transitory computer readable medium comprising instructions stored therein that when executed by one or more multi-core processors cause the one or more multi-core processors to perform:
obtaining 2-dimensional (2D) image data representing a 1-dimensional (1D) barcode within a first image area;
generating a plurality of scanlines across the first image area;
for each of the plurality of scanlines,
synchronizing the scanline, including decoding an initial set of numerical digits represented by the scanline, in which said synchronizing provides a scale estimate for the scanline;
using a path decoder to decode remaining numerical digits within the scanline, the path decoder decoding multiple numerical digits in groups, in which the scale estimate is adapted as the remaining numerical digits are decoded; and
providing decoded numerical digits as an identifier represented by the scanline.
