« Recyclages audiovisuels dans le documentaire de création contemporain »

2022

La numérisation à grande échelle et la mise en ligne des fonds d’archives filmiques, la prolifération d’images sur internet, notamment depuis l’apparition de YouTube en 2005, ou encore les techniques numériques de traitement des images ont favorisé l’essor des films de found footage –littéralement enregistrements ou images trouvés–, une modalité qui est devenue une tendance marquante du documentaire contemporain. Certaines de ces œuvres, parfois constituées intégralement d’images de « seconde main » (Blümlinger, 2013), au-delà de la reconnaissance critique et de l’intérêt des chercheurs, ont connu le succès en salles ou sur les plateformes et ont été projetées et récompensées dans les festi…

Novel VAMPIRE algorithms for quantitative analysis of the retinal vasculature

2013

This paper summarizes three recent, novel algorithms developed within VAMPIRE, namely optic disc and macula detection, arteryvein classification, and enhancement of binary vessel masks, and their performance assessment. VAMPIRE is an international collaboration growing a suite of software tools to allow efficient quantification of morphological properties of the retinal vasculature in large collections of fundus camera images. VAMPIRE measurements are currently mostly used in biomarker research, i.e., investigating associations between the morphology of the retinal vasculature and a number of clinical and cognitive conditions.

On the use of multi-temporal series of COSMO-SkyMed data for LANDcover classification and surface parameter retrieval over agricultural sites

2011

The objective of this paper is to report on the activities carried out during the first year of the Italian project “Use of COSMO-SkyMed data for LANDcover classification and surface parameters retrieval over agricultural sites” (COSMOLAND), funded by the Italian Space Agency. The project intends to contribute to the COSMO-SkyMed mission objectives in the agriculture and hydrology application domains.

Ricarda Huchs Spuren im kultur- und geistesgeschichtlichen Raum Italiens

2020

Artykuł podejmuje próbę rekonstrukcji „śladów“ literackich „wielkiej damy“ literatury niemieckiej – Ricardy Huch – na obszarze idei myśli krajów śródziemnomorskich na przykładzie Włoch. Na przełomie wieków XIX i XX Huch zainteresowała się jako historyk i powieściopisarz historią walk narodowowyzwoleńczych we Włoszech i wystawiła swoisty pomnik literacki bohaterom włoskiego risorgimento. Również przeżycia osobiste związane z Italią, znalazły wydźwięk w powieści społecznej Aus der Triumphgasse [Z alei wolności].

Contributions à l’imagerie polarimétrique et à ses applications en vision pour la robotique

2019

Ce mémoire présente le bilan de l'ensemble de mes travaux de recherche effectués de septembre 2006 à juin 2019 au sein de l'équipe Creusotine du laboratoire Le2i devenue équipe Vibot ERL CNRS 6000 depuis janvier 2018. Les principales activités de recherche que j'ai menées au cours de ces 10 dernières années autour de l'imagerie polarimétrique, de la vision omnidirectionnelle et de leurs applications en vision pour la robotique seront particulièrement détaillées dans ce document. Elles seront présentées selon deux grandes parties : la première concernera plutôt l'aspect mise en œuvre et calibrage des caméras et la seconde se concentrera sur les applications potentielles en vision pour la rob…

Intravenous Contrast Material for Cardiac Computed Tomography

2023

Purpose: The Italian Registry of Contrast Material use in Cardiac Computed Tomography (iRCM-CCT) is a multicenter, multivendor, observational study on the use of contrast media (CM) in patients undergoing cardiac computed tomography (CCT). The aim of iRCM-CCT is to assess image quality and safety profile of intravenous CM compounds. Materials and methods: iRCM-CCT enrolled 1842 consecutive patients undergoing CCT (≥50 per site) at 20 cluster sites with the indication of suspected coronary artery disease. Demographic characteristics, CCT, and CM protocols, clinical indications, safety markers, radiation dose reports, qualitative (ie, poor vascular enhancement) and quantitative (ie, HU attenu…

Verifica di DSM ottenuti da coppie stereoscopiche EROS B

2009

La continua e crescente disponibilità di sensori satellitari ad alta ed altissima risoluzione (inferiore ad 1 metro) rappresentano una eccellente fonte per scopi cartografici. In particolare quelli in grado di acquisire coppie stereoscopiche (tra cui Ikonos, QuickBird ed EROS) forniscono una valida possibilità per la generazione di modelli digitali di superficie (Digital Surface Model, DSM). Il lavoro svolto descrive lo studio condotto per la verifica di DSM ottenuti tramite procedure di image-matching da una coppia di immagini stereoscopiche del satellite EROS. Lo studio è stato sviluppato nell’ambito delle ricerche già condotte dagli autori su queste tematiche relative a coppie stereoscop…

Kreowanie wizerunku placówki oświatowej – perspektywa teoretyczna i praktyczna

2022

Dynamicznie zmieniający się rynek usług edukacyjnych oraz wzrastające wymagania społeczne kierowane wobec instytucji edukacyjnych i jej przedstawicieli uzależniły sukces współczesnej szkoły od wypracowania atrakcyjnej marki w środowisku, umożliwiającej wyróżnienie się na tle konkurencji oświatowej i pozyskanie potencjalnych klientów usług edukacyjnych (rodziców i ich dzieci). Dlatego w opracowaniu zostały zaprezentowane najważniejsze elementy składające się na proces kształtowania pozytywnego i spójnego wizerunku placówki edukacyjnej w środowisku lokalnym, zarówno z perspektywy teoretycznej, jak i praktycznej. Przedstawiono propozycję autorskiego modelu strategii kreowania wizerunku i promo…

Analysis of microtomographic images of porous heterogeneous materials

2015

In this work, we study the phases of image processing chain of microtomographic imag- ing in order to obtain reliable results while optimizing the time spent on denoising and segmentation. We consider that the decisions made at the early phases of the processing chain are most important and the selection made there essentially determine the overall quality of imaging process. We also compare here various denoising method qualita- tively, however, we think that the pure noise removal ability is not the only requirement for noise removal in microtomographic images. By proper denoising we can affect selec- tion of segmentation methods and, thus, also the quality of the analysis. Additionally, …
