Classification: CPC G | IPC G

Claim 0:
1. A method comprising:
estimating a module size of a barcode image (BI) based on geometric characteristics of a plurality of pixel groups, each of the plurality of pixel groups comprising one or more connected pixels of a first color;
rescaling the BI based on the estimated module size;
processing the rescaled BI using a neural network (NN) to obtain candidate locations of modules in the BI and a map of binarized pixel intensities of the BI;
identifying associations of grid positions in a grid of modules (GoM) with the candidate locations of modules in the BI, wherein an association of each of at least a subset of the grid positions in the GoM is identified based on one or more associations identified for other grid positions in the GoM; and
decoding the BI, using the GoM and the map of binarized pixel intensities.
