Abstract
Disclosed is a method and apparatus for discerning the presence of one or more bar codes within the image of a scanned document and making the bar code data available to a document image management system. The scanned image is represented by a bit map which is searched for data blocks, such having been formed by a smearing technique. Each data block is analyzed to find bar code candidates which are then subjected to a dynamic width determination process so that an attempt to read them as a bar code can be made.
