1. A system, comprising: a processor-implemented barcode classifier module configured to: generate a classification determination for each of a plurality of estimated barcode digits corresponding to an estimated decoded barcode, the classification determination being one of a first classification determination and a second classification determination; and aggregate first classification determinations among a plurality of classification determinations for the plurality of estimated barcode digits; and a processor-implemented barcode comparator module configured to compare the aggregated first classification determinations with a first predetermined threshold to determine a validity of the decoded barcode estimation.
