A System for the Automated Reading of Check Amounts - Some Key Ideas

In this paper we present a reading system for amounts extracted from bank and postal checks. We focus our description on the legal amount recognition and the combination of the recognition results for the legal and the courtesy amounts. For these tasks we developed and applied several new techniques. In our work we deal with German check amounts. The automated reading of German legal amounts is a great challenge since the literal words the legal amount is constructed of are completely connected. Our system was tested on a database with real checks from the Swiss postal services.
