Text localization from photos

2009

In this paper a new text extraction algorithm is proposed. In real scenes the text is usually overlapped or is part of the background. To identify the text regions, in complex conditions, a method exploiting a “multi-resolution feature based method” for extracting text with undefined dimension has been developed. Once identified, the multi-resolution information are merged and skimmed through a set of Support Vector Machines (SVM). The tests and the comparisons with other techniques, performed on heterogeneous images, have shown the effectiveness of the proposed.

Automatic Volumetric Liver Segmentation Using Texture Based Region Growing

2010

In this paper an automatic texture based volumetric region growing method for liver segmentation is proposed. 3D seeded region growing is based on texture features with the automatic selection of the seed voxel inside the liver organ and the automatic threshold value computation for the region growing stop condition. Co-occurrence 3D texture features are extracted from CT abdominal volumes and the seeded region growing algorithm is based on statistics in the features space. Each CT volume is composed by 230 slices, having 512 x 512 pixels as spatial resolution, and 12-bit gray level resolution. In this initial feasible study, 5 healthy volunteer acquisitions has been used. Tests have been p…

Alcune riflessioni su The Force of Law di Schauer

2018

In this article, I will analyze some arguments developed by Schauer in this book The Force of Law, in particular the role of the coercion in law. Coercion is not only a typical feature of law, but is an empirical-universal feature, present in all systems of positive law which exist, will ever exist and historically existed.

The beginning of the Neolithic in Southern Italy and Sicily

2018

Abstract The process of Neolithization of Southern Italy and Sicily covers about 500 years (6200–5700 cal BC) and involves two cultural horizons: Archaic Impressed Ware or “Impresse Arcaiche” and Advanced Impressed Ware or “Impresse Evolute”. In Southern Italy the Neolithic peopling from the East is characterized by a “package” of plenty domesticated plants and livestock; in Sicily the adoption of the new economical system is apparently more slow and with no evidences of ruptures between the Mesolithic groups and first farmers. In this paper we present the chronological and cultural framework of the sixth millennium BC within the area of investigation, with an up-to-date bibliography about …

Early pastoral communities in the mountains of Sicily. Prehistoric evidence from Vallone Inferno (Scillato) in the palaeoenvironmental framework of t…

2021

Abstract This paper discusses the Middle Neolithic and the Early Bronze Age phases of the occupation of a rock shelter at Vallone Inferno (Scillato, Palermo) in Sicily. Vallone Inferno is a key site for studying the early establishment and development of pastoralism in the prehistoric mountainous environments of Sicily. Seasonal use of the site as a shelter is documented for the earliest pastoral communities that exploited the Madonie mountain range. The results of the analysis of pottery and lithic assemblages contribute to the definition of two chronocultural frameworks that were linked by the same economic subsistence base. The special role of obsidian emerges, while the mobility pattern…

Within the symbolic world of the prehistoric hunters: A GIS-based and 3D model analysis of sites with complexes of linear incisions in western Sicily

2021

Abstract The prehistoric peopling of Sicily has left scattered traces of symbolic activities through well-known rock art expressions in caves and rock shelters located all around the island (among the most significant, the sites of Addaura, Racchio and Genovese). A peculiar phenomenon is the incision of linear signs, often grouped on the same rocky walls, hidden in fissures or placed at the entrance of the underground chambers of caves. In this report, we investigate a sample of these graphic expressions from a spatial and technical point of view. A GIS-based approach presents the territorial pattern providing insight, on a macroscale, into the intentional positioning of the sign complexes.…

New data on Sicilian prehistoric and historic evolution in a mountain context, Vallone Inferno (Scillato, Italy)

2013

Vallone Inferno rock-shelter is an archaeological site located in the Madonie mountain range in Sicily. Archaeological excavation and research have provided a long prehistoric and historic sequence from the Neolithic to the medieval period, this being the most complete work in this area at present. In this paper we present the preliminary data provided by a multidisciplinary study based on pottery, lithic, human, faunal and plant remains. Stratigraphic studies have identified four complexes, of which complex 3 has provided almost all the archaeological remains. 14C AMS dates, obtained from four samples, place the human activities between 2601 cal BC and 644 cal AD. These dates are coherent …

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…

Settore L-FIL-LET/12 - Linguistica ItalianaAmong the «Editorial problems» that emerged during the control and organization of the materials coming from the survey campaign of the Atlante Linguistico del Mediterraneo (ALM) Berruto (1971-1973) notes the proliferation and heterogeneity of some graphemic choices made by different field researchers. As they were engaged in a more or less punctual transcription of the answers obtained they had interpreted and solved differently some of the directions provided in the phonetic transcription system that accompanied the Questionnaire. The picture relating to the transcription of some consonants of the palatal sector had emerged as particularly complex since the graphemes (and the corresponding phones) foreseen in the original system (ALM 1959) were insufficient. Not even the 1971 updates meant to improve the representation of some phonetic features emerged from the investigations in the operations of Response reviewing allowed to obtain a clear homogeneous picture regarding the «plosive palatal» consonants. With regard to the phonetic trait under scrutiny I have already had the opportunity to propose a path aiming to the achievement of possible operational solutions. This has taken place in view of the planned simplification / homologation and transcoding phase from the ALM original system to the IPA one - while proceeding from the examination of the Schedoni’s current state with regard to the surveys referring to central-southern Italy Corsica and Sicily (see Matranga 2019). The scope is now to investigate the same phonetic trait as proven in the materials about the surveys carried out by Lirak Dodbiba in the ALM’s three Albanian points.

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.

Settore L-FIL-LET/14 - Critica Letteraria E Letterature ComparateBetween late XIX and the first 30 years of the XX Century some Italians immigrated to the United States – such as Bernardino Ciambelli Italo Stanco Garibaldi Marto Lapolla Louis Forgione Michael Fiaschetti and Prosper Buranelli – wrote some texts that starting from the typical features of Mystery (serialization and incardination of the fabula in a specific urban context) together with some of the characteristic elements of the Hard boiled never lose sight of the peculiar 'mission' of political economic and social denunciation. Taking the political and social problems as the primary key of their works these writers want to remove the defamatory role attributed by the public opinion fomented by the press to Italian immigrated community. Their works don’t have the main intent to stage detectives that can solve a case or unmask a culprit but rather they aim to denounce social distortions corruption and injustices suffered by an entire community and not least to indicate the picture of what on the contrary that same society could have been.
