Hyper-spectral Analysis for Automatic Signature Extraction
Résumé
Signatures are one of the most accessible and prevailed ways of authenticating documents.
Over the last many years, a large number of signature veri cation systems have been reported. A
common assumption in nearly all of these system is that the signatures are available readily extracted
from documents. In this paper we provide a detailed literature survey on the subject and argue
that pre-extracted signatures are not always available especially in forensic cases. Furthermore, we
present a novel system of automatically extracting signatures from documents with the help of
hyper-spectral imaging. Initial experiments reveal that the proposed idea possess great potential to
form a baseline signature extraction system above whom any signature veri cation system can be
adjuncted for signature veri cation.
