Abstract

See full text

Systems and methods for decoding a barcode are disclosed. A scan signal for a first portion of the barcode is acquired. Integrated sub-character barcode feature evidence for the barcode is stored including evidence for a first plurality of possible sub-character barcode feature interpretations for a first plurality of sub-character barcode features. Sub-character barcode feature measurements are extracted for a second plurality of sub-character barcode features from the scan signal. Sub-character barcode feature evidence is determined for the second plurality of sub-character barcode features, including evidence for a second plurality of possible sub-character barcode feature interpretations for the second plurality of sub-character barcode features. Whether a portion of the integrated sub-character barcode feature evidence corresponds to a portion of the sub-character barcode feature evidence is determined. The sub-character barcode feature evidence is integrated into the integrated sub-character barcode. Character values are determined from the integrated sub-character barcode feature evidence.
