ABSTRACT:
A system and method are disclosed for recognizing the type of an electronically stored image of a document. The method is composed of two parts: form signature computation, and signature matching. For form acquisition, signatures of forms are computed and stored in a template data base. For recognition, the signature of the input form is computed, and the best match between it and the signatures in the template data base is found. The input form is then considered to be the same as the form from which the best matching signature was computed.
