Entropy-based Localization of Textured Regions

2011

Appearance description is a relevant field in computer vision that enables object recognition in domains as re-identification, retrieval and classification. Important cues to describe appearance are colors and textures. However, in real cases, texture detection is challenging due to occlusions and to deformations of the clothing while person's pose changes. Moreover, in some cases, the processed images have a low resolution and methods at the state of the art for texture analysis are not appropriate. In this paper, we deal with the problem of localizing real textures for clothing description purposes, such as stripes and/or complex patterns. Our method uses the entropy of primitive distribu…

La questione delle «esplosive palatali» nelle inchieste dell’Atlante Linguistico del Mediterraneo (ALM): l’area italiana centromeridionale

2019

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…

Community and space in Italian sociolinguistics: The experience of the Linguistic Atlas of Sicily (Atlante Linguistico della Sicilia -- ALS)

2017

The paper focuses on the notions of ‘space’ and ‘community’ within the most recent developments of Italian sociolinguistics. This research area has roots in the tradition of Italian geolinguistic studies and has been enhanced by other research traditions. In fact, Italian sociolinguistics has reused the relationship between ‘community’ and ‘space’ investigated in the early twentieth century by Benvenuto Terracini’s (1886–1968) seminal studies on ‘minimal linguistic point’ (‘punto linguistico minimo’) and on ‘community of speakers’. Since the 1970s and, with more weight, in the last decades, some important contributions coming from scholars such as Alberto Sobrero, Tullio Telmon and Giovanni…

Rappresentare le spazialità complesse. L’esperienza dell’ALS (Atlante linguistico della Sicilia)

2016

Dans cet article, nous nous occuperons des données quantitatives et qualitatives recueillies durant les vingt-cinq dernières années en Sicile. Ces données ont été collectées dans le cadre d’une enquête sur le terrain de grande ampleur qui a intéressé la Sicile entière dans le contexte des activités de l’Atlas linguistique de la Sicile (ALS). En particulier, nous observerons les données sur la perception et sur la représentation des différences linguistiques recueillies à travers trois questions du questionnaire ALS. Nous présenterons aussi une proposition de cartographie pluridimensionnelle de ces données. Pour l’analyse, l’interprétation et la cartographie des données nous avons élaboré un…

L’informatica nella ricerca geolinguistica. L’esperienza siciliana

2019

La ricerca dialettologica ha risentito molto di alcuni momenti dello sviluppo tecnologico e, successivamente, di quello informatico, non soltanto sul piano del rinnovamento metodologico, ma anche su alcuni aspetti teorici di questa disciplina. Insieme ad alcune considerazioni di ordine generale, l’implicazione dell’informatica nella ricerca dialettologica, e in quella geolinguistica in particolare, sarà valutata e discussa attraverso il piano operativo di uno specifico progetto di ricerca geo(socio)linguistico: quello dell’Atlante Linguistico della Sicilia (ALS). Dialectological research has been widely affected by technological advances to some extent and, as a result, by computer sciences…

2020

In this article I discuss some interactional aspects regarding the relation between the participants in the sociolinguistic interview. In particular, I show how interviewers and interviewees work together in order to co-construct the (socio)linguistic data. In this perspective, I analyse the ways in which the participants make observable to each other their interactional roles through the interview. Moreover, I focus on the relation between the individuals taking part in the interview and the invisible, yet influential members of the research group. I show how the latter may affect the interactional moves of the former, but also how participants account for the research group’s role. The an…

Segmentation automatique et analyse de forme d'hippocampes humains dans l'étude de la maladie d'Alzheimer

2011

The aim of this thesis is to investigate the shape change in hippocampus due to the atrophy in Alzheimer’s disease (AD). To this end, specific algorithms and methodologies were developed to segment the hippocampus from structural magnetic resonance (MR) images and model variations in its shape. We use a multi-atlas based segmentation propagation approach for the segmentation of hippocampus which has been shown to obtain accurate parcellation of brain structures. We developed a supervised method to build a population specific atlas database, by propagating the parcellations from a smaller generic atlas database. Well segmented images are inspected and added to the set of atlases, such that t…

Search for WH production with a light Higgs boson decaying to prompt electron-jets in proton–proton collisions at \(\sqrt {s}=7\)  TeV with the ATLAS…

2013

A search is performed for WH production with a light Higgs boson decaying to hidden-sector particles resulting in clusters of collimated electrons, known as electron-jets. The search is performed with 2.04 fb[superscript −1] of data collected in 2011 with the ATLAS detector at the Large Hadron Collider in proton–proton collisions at √s=7 TeV . One event satisfying the signal selection criteria is observed, which is consistent with the expected background rate. Limits on the product of the WH production cross section and the branching ratio of a Higgs boson decaying to prompt electron-jets are calculated as a function of a Higgs boson mass in the range from 100 to 140 GeV.
