Όνομα Συνεδρίου:International Workshop on Automated Forensic Handwriting Analysis
This work presents a feature extraction method for
writer verification based on their handwriting. Motivation for
this work comes from the need of enchancing modern eras
security applications, mainly focused towards real or near to real
time processing, by implementing methods similar to those used
in signature verification. In this context, we have employed a full
sentence written in two languages with stable and predefined
content. The novelty of this paper focuses to the feature
extraction algorithm which models the connected pixel
distribution along predetermined curvature and line paths of a
handwritten image. The efficiency of the proposed method is
evaluated with a combination of a first stage similarity score and
a continuous SVM output distribution. The experimental
benchmarking of the new method along with others, state of the
art techniques found in the literature, relies on the ROC curves
and the Equal Error Rate estimation. The produced results
support a first hand proof of concept that our proposed feature
extraction method has a powerful discriminative nature.
