Abstract
In a bar code scanning system, character reconstruction and element level processing techniques enable label information to be recreated from defective or corrupted information that would otherwise be undecodable by standard decoding algorithms. Reconstruction methods allow for undecodable characters or elements to be reconstructed from partial information based upon known or expected structural characteristics for the particular label symbologies being decoded. Element edge histograms, edge strength indicators and quality measures are used to enhance label readability and bar code scanner decoding capabilities.
