A novel methodology for writer (hand) identification: establishing Rigas Feraios wrote two important Greek documents discovered in Romania

Abstract

The main goal of the present work is to determine the hand that has written two newly discovered documents in Romania. For giving the proper answer, the authors introduced the notion of “Ideal Representative”, namely of an object that very well represents the corresponding ideal alphabet symbol that a writer had in his/her mind when writing a document by hand. Moreover, the authors have introduced a novel method, which leads to the optimal evaluation of the Ideal Representative of any alphabet symbol in association with any handwritten document. Furthermore, the authors have introduced methods for comparing these Ideal Representatives, so as a final decision about the hand that has written a document may be obtained with a highly considerable likelihood. The related analysis manifests that the two documents discovered in Romania in 1998, belong to the great personality of Rigas Feraios. The presented method of automatic handwriting Identification seems to be of general applicability.

Teaching Old Presumptive Tests New Digital Tricks with Computer Vision for Forensic Applications

“…The use of digital imaging in forensic applications is well established across a range of use cases. Applications span handwriting recognition, 12 face detection, 13 security screening, 13 blood stain characterisation, [14][15][16] identification of chemical warfare agents, 17 quantifying explosives, 18 and ballistics. 19 More specifically within presumptive testing, smart phoneenabled single imaging approaches have been applied to, for example, recreational drug detection in drinks, 20 risk-mitigating false positives in cocaine detection, 21 bodily fluid identification, 15 digitalising amphetamine spot tests, 22 and micro-device fabrication for more objective spot testing.…”
