Storia di Montalbano

2018

Questo libro raccoglie gli scritti che Gianfranco Marrone ha dedicato alla figura del commissario di polizia Salvo Montalbano: personaggio a tutto tondo di intramontabile successo, e modello di riferimento per numerosissimi avatar letterari, televisivi, mediatici. Tali scritti mettono alla prova i modelli d’analisi della semiotica su un ampio spettro ampio di opere e testi in costante dialogo fra loro (romanzi, film, fumetti, pietanze, itinerari turistici…), studiandoli ai loro diversi livelli e dimensioni del senso. Una ricostruzione al tempo stesso puntigliosa e profonda di un universo sociale e antropologico, geografico e ideologico – quello camilleriano e montalbanesco – che fatica a po…

Itsemurhatartunnan taikauskosta: The Moth Diaries (2011) ja 13 Reasons Why (2017)

2018

Artikkeli käsittelee kahden itsemurhaa kuvaavan populaarikulttuurin tapausesimerkin, The Moth Diaries -elokuvan ja 13 Reasons Why -sarjan, ja tabun käsitteen välityksellä itsemurhaan liitettyä tartunnan pelkoa ja tämän pelon ilmenemistä viihteen ja median representaatioita säätelevässä Werther-efektissä. Keväällä 2017 julkaistun kohutun 13 Reasons Why -Netflix-sarjan ensimmäisen kauden vastaanotto ilmentää sosiologien, psykologien ja kansanterveystieteilijöiden tunnetuksi tekemää Werther-efektiä, median välittämäksi pelättyä itsemurhatartuntaa. Kanadalainen kauhudraama The Moth Diaries (2011) taas käsittelee sisällössään vanhemmalta lapselle periytyvää itsemurhatartuntaa vampyyrin hahmon vä…

A Shape-based Statistical Method to Retrieve 2D TRUS-MR Slice Correspondence for Prostate Biopsy

2012

International audience; This paper presents a method based on shape-context and statistical measures to match interventional 2D Trans Rectal Ultrasound (TRUS) slice during prostate biopsy to a 2D Magnetic Resonance (MR) slice of a pre-acquired prostate volume. Accurate biopsy tissue sampling requires translation of the MR slice information on the TRUS guided biopsy slice. However, this translation or fusion requires the knowledge of the spatial position of the TRUS slice and this is only possible with the use of an electro-magnetic (EM) tracker attached to the TRUS probe. Since, the use of EM tracker is not common in clinical practice and 3D TRUS is not used during biopsy, we propose to per…

Una sociologia della condivisione. Comunicare per condividere due

2014

Ricerca dedicata ai fenomeni di condivisione che si diffondono in questo tempo di crisi finanziaria e economica. Se ne studiano gli aspetti più diversi: dal socioantropologico al linguistico e comunicativo, dall'economico al politico It's a research on sharing facts: they refer to access and not to the property in a period of finance and economy crisis. The author studies many aspects: from socioanthropological to linguistic and communicative, from economic up to politic ones.

Image inpainting using directional wavelet packets originating from polynomial splines

2020

The paper presents a new algorithm for the image inpainting problem. The algorithm is using a recently designed versatile library of quasi-analytic complex-valued wavelet packets (qWPs) which originate from polynomial splines of arbitrary orders. Tensor products of 1D qWPs provide a diversity of 2D qWPs oriented in multiple directions. For example, a set of the fourth-level qWPs comprises 62 different directions. The properties of the presented qWPs such as refined frequency resolution, directionality of waveforms with unlimited number of orientations, (anti-)symmetry of waveforms and windowed oscillating structure of waveforms with a variety of frequencies, make them efficient in image pro…

A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens

2017

The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approac…

“Congratulations, you’re on TV!”: Middle-space performances of live tweeters during the FIFA World Cup

2018

Social television has transformed the traditional role of the television viewers by providing ‘ordinary people’ access to the public stage. This article describes how public access to television affected the dialogues of Finnish tweeters on Twitter during the massive media event of the FIFA World Cup. Through the lens of digital conversation analysis, the study shows how the media publicity of tweets changed the direction of the interaction between tweeters and transformed their roles vis-à-vis the television show, making one of them into a ‘media flasher’ and the others viewers of his or her performance. The publicity was constructed as important through noticings, congratulations, and com…

Video Scene analysis for a configurable hardware accelerator dedicated to Smart Camera

2012

International audience; According to the Center for Research and Prevention of Injuries report, fall-caused injuries of elderly people in UE- 27 are five times as frequent as other injury causes which reduce considerably their mobility and independence. Among the diverse applications of computer vision systems, object detection and event recognition are of the most prominent related recognition and motion analysis, that is, researchers had the idea to spread it in fall detection. The fall event, extracted automatically from the video scene represents itself, crucial information that can be used to alert emergency. In this context, visual information on the corresponding scene is highly impo…
