La problemática textual del comentario de Galeno al tratado hipocrático Sobre los humores
2014
The commentary to the Hippocratic treatise De humoribus, which was accepted as an authentic Galenic work till recent times, uses to be nowadays assigned to a mid-XVIth. century author of false ancient manuscripts, the Greek Andreas Darmarios. In spite of this, the text presents several kinds of problems that suggest a careful revisiting of the question. This article presents some of such problems and looks for a different explanation by means of the interaction of the languages involved in the transmission of the text.
Toward an Integrated System for Surveillance and Behaviour Analysis of Groups and People
2013
Security and INTelligence SYStem is an Italian research project which aims to create an integrated system for the analysis of multi-modal data sources (text, images, video, audio), to assist operators in homeland security applications. Within this project the Scientific Research Unit of the University of Palermo is responsible of the image and video analysis activity. The SRU of Palermo developed a web service based architecture that provides image and video analysis capabilities to the integrated analysis system. The developed architecture uses both state of the art techniques, adapted to cope with the particular problem at hand, and new algorithms to provide the following services: image …
Copy–Move Forgery Detection by Matching Triangles of Keypoints
2015
Copy-move forgery is one of the most common types of tampering for digital images. Detection methods generally use block-matching approaches, which first divide the image into overlapping blocks and then extract and compare features to find similar ones, or point-based approaches, in which relevant keypoints are extracted and matched to each other to find similar areas. In this paper, we present a very novel hybrid approach, which compares triangles rather than blocks, or single points. Interest points are extracted from the image, and objects are modeled as a set of connected triangles built onto these points. Triangles are matched according to their shapes (inner angles), their content (c…
A tool to support the creation of datasets of tampered videos
2015
Digital Video Forensics is getting a growing interest from the Multimedia research community, as the need for methods to validate the authenticity of a video content is increasing with the number of videos freely available to the digital users. Unlike Digital Image Forensics, to our knowledge, there are not standard datasets to test video forgery detection techniques. In this paper we present a new tool to support the users in creating datasets of tampered videos. We furthermore present our own dataset and we discuss some remarks about how to create forgeries difficult to be detected by an observer, to the naked eye.
State of the art in passive digital image forgery detection: copy-move image forgery
2017
Authenticating digital images is increasingly becoming important because digital images carry important information and due to their use in different areas such as courts of law as essential pieces of evidence. Nowadays, authenticating digital images is difficult because manipulating them has become easy as a result of powerful image processing software and human knowledge. The importance and relevance of digital image forensics has attracted various researchers to establish different techniques for detection in image forensics. The core category of image forensics is passive image forgery detection. One of the most important passive forgeries that affect the originality of the image is cop…
Les premiers fers pendant l'âge du Bronze en France. Données nouvelles
2022
If iron was used in Asia Minor from the 3rd millennium BC, it was not known in Western Europe until the 13th century BC. In France, its first appears towards the end of the Bronze Age, possibly during the 13th century BC (Bronze final I / Bz D). Iron has been subsequently documented, especially during the 9th century BC (Bronze final IIIb / Late Atlantic Bronze Age 3 / Bz B2-3). Metallurgic iron is known only during this last stage of Late Bronze Age. The inventory of objects found in France, drawn up in 1981 and revised in 2009 has not changed much, despite several recent studies. However renewed data, with new discoveries and some objects removed from the list, call for an updated overvie…
Haavoittuvuuksien torjunta defensiivisillä ohjelmointikeinoilla PHP-sovelluksissa
2012
Tutkielmassa kartoitetaan, kuinka SQL-injektioita, Cross-Site Scripting -hyökkäyksiä ja Cross-Site Request Forgery -hyökkäyksiä voidaan ehkäistä PHP-sovelluksissa defensiivisillä ohjelmointimenetelmillä. This thesis explores the defensive programming techniques for preventing SQL injections, Cross-Site Scripting attacks and Cross-Site Request Forgery attacks in PHP applications.
