Design and Implementation of an Efficient Fingerprint Features Extractor
2014
Biometric recognition systems are rapidly evolving technologies and their use in embedded devices for accessing and managing data and resources is a very challenging issue. Usually, they are composed of three main modules: Acquisition, Features Extraction and Matching. In this paper the hardware design and implementation of an efficient fingerprint features extractor for embedded devices is described. The proposed architecture, designed for different acquisition sensors, is composed of four blocks: Image Pre-processor, Macro-Features Extractor, Micro- Features Extractor and Master Controller. The Image Pre- processor block increases the quality level of the input raw image and performs an a…
PHOTOGRAMMETRY NOW AND THEN - FROM HAND-CRAFTED TO DEEP-LEARNING TIE POINTS
2022
Abstract. Historical images provide a valuable source of information exploited by several kinds of applications, such as the monitoring of cities and territories, the reconstruction of destroyed buildings, and are increasingly being shared for cultural promotion projects through virtual reality or augmented reality applications. Finding reliable and accurate matches between historical and present images is a fundamental step for such tasks since they require to co-register the present 3D scene with the past one. Classical image matching solutions are sensitive to strong radiometric variations within the images, which are particularly relevant in these multi-temporal contexts due to differen…
Retinal image synthesis through the least action principle
2020
Eye fundus image analysis is a fundamental approach in medical diagnosis and follow-up ophthalmic diagnostics. Manual annotation by experts needs hard work, thus only a small set of annotated vessel structures is available. Examples such as DRIVE and STARE include small sets for training images of fundus image benchmarks. Moreover, there is no vessel structure annotation for a number of fundus image datasets. Synthetic images have been generated by using appropriate parameters for the modeling of vascular networks or by methods developing deep learning techniques and supported by performance hardware. Our methodology aims to produce high-resolution synthetic fundus images alternative to the…
A syntactic analysis of the subject clitic a in the Friulian variety of Campone
2015
This article presents a syntactic analysis of the third person subject clitic a in Camponese, a heretofore unstudied Friulian variety. Following Poletto's (2000) map of subject clitics, we argue that it bears [+third person] features, and is, in fact, the spell-out of the functional head Subj°, located in the highest projection of TP (following Rizzi & Shlonsky 2007). In the first part of the article, we offer a detailed description of the distribution and syntactic properties of the subject clitic a, identifying its position in relation to the other elements that occur in the CP and TP. In the second part we discuss two proposals put forward to account for split clitics like a-l in the…
Ancora sulle "esplosive palatali" nelle inchieste dell'Atlante Linguistico del Mediterraneo (ALM): i punti albanesi
2021
Tra i «Problemi redazionali» emersi in fase di controllo e organizzazione dei materiali giunti dalla campagna di rilevamenti dell’Atlante Linguistico del Mediterraneo (ALM), Berruto (1971-1973) rileva la proliferazione e l’eterogeneità di alcune scelte grafemiche operate da diversi raccoglitori che, impegnati in una trascrizione più o meno puntuale delle risposte ottenute, avevano interpretato e risolto variamente alcune delle indicazioni previste nel sistema di trascrizione fonetica che accompagnava il Questionario. Particolarmente complesso era emerso il quadro relativo alla trascrizione di alcune consonanti del settore “palatale”, per le quali i grafemi (e i foni a essi corrispondenti) p…
Il Polar prima del Polar: il poliziesco italo-americano tra fine Ottocento e gli anni Trenta del Novecento
2018
Tra la fine dell’Ottocento e gli anni Trenta del Novecento, alcuni Italiani immigrati negli Stati Uniti – quali, fra gli altri, Bernardino Ciambelli, Italo Stanco, Garibaldi Marto Lapolla, Louis Forgione, nonché il sodalizio letterario costituito da Michael Fiaschetti e Prosper Buranelli – si sono cimentati nel genere del poliziesco con alcuni testi che, partendo da alcune delle caratteristiche tipiche del Mystery, quali la serializzazione e l’incardinamento della fabula in uno specifico contesto urbano, insieme ad alcuni degli elementi caratteriali dei personaggi dell’Hard boiled non perdono mai di vista la peculiare ‘missione’ di denuncia politica, economica e sociale. Facendo del problem…

Automatic differentiation of melanoma from dysplastic nevi.
2015
International audience; Malignant melanoma causes the majority of deaths related to skin cancer. Nevertheless, it is the most treatable one, depending on its early diagnosis. The early prognosis is a challenging task for both clinicians and dermatologist, due to the characteristic similarities of melanoma with other skin lesions such as dysplastic nevi. In the past decades, several computerized lesion analysis algorithms have been proposed by the research community for detection of melanoma. These algorithms mostly focus on differentiating melanoma from benign lesions and few have considered the case of melanoma against dysplastic nevi. In this paper, we consider the most challenging task a…
Lingvistiskās pazīmes tvītos
2018
Mūsdienās, gan personiskajā, gan profesionālajā dzīvē liela nozīme ir komunikācijas prasmēm. Dažādas sociālās platformas kā, piemēram, Tviters sniedz iespēju komunicēt efektīvak, dalīties ar nozīmīgu informāciju un publiski izteikt savu viedokli. Bakalaura darba mērķis ir izpētīt lingvistiskās iezīmes, kas raksturo tvītus. Kā pētījuma objekts tika izvēlēti politiķa ASV prezidenta Donalda Trampa tvīti. Pētījuma materiāli sastāvēja no 100 nejauši izvēlētiem tvītiem. Tika pielietotas divas pētījuma metodes – diskursa analīze un vārdu biežuma analīze. Diskursa analīzes metode tika pielietota ar mērķi noteikt Donalda Trampa valodas lietojuma paradumus. Savukārt, vārdu biežuma analīzes metode ļāv…
