Contributions à l'analyse et à l'interprétation des images : Extraction et représentation de caractéristiques

2016

Ce mémoire, rédigé en vue de l'obtention de l'Habilitation à Diriger des Recherches (HDR), offre un aperçu des travaux de recherche et d’encadrement que j’ai pu mener depuis l'obtention de mon doctorat. Il montre la diversité des champs d’application et de recherche (en vision et en imagerie médicale) que j’ai pu couvrir , ainsi que mon implication dans l’encadrement doctoral.Mes activités de recherche se divisent en deux grandes parties. D'une part, l'analyse de scènes dynamiques, à savoir la détection de regions d'intérêt dans des séquences d'images, pour réduire la taile des données à traiter, et la détection et le suivi d'objets mobiles à l'aide de caméras de diverses natures (perspecti…

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…

Visual saliency by keypoints distribution analysis

2011

In this paper we introduce a new method for Visual Saliency detection. The goal of our method is to emphasize regions that show rare visual aspects in comparison with those showing frequent ones. We propose a bottom up approach that performs a new technique based on low level image features (texture) analysis. More precisely, we use SIFT Density Maps (SDM), to study the distribution of keypoints into the image with different scales of observation, and its relationship with real fixation points. The hypothesis is that the image regions that show a larger distance from the mode (most frequent value) of the keypoints distribution over all the image are the same that better capture our visual a…

L'indicible et l'indiciel : empreinte gustative et trace figurative

2011

International audience; « On peut, tout au plus, prendre en considération un type dé-terminé d'icône à forte valeur émotive, celle que nous appellerons « icône gastronomique » et qui se manifeste lorsque la qualité d'un objet (buée glacée sur un verre de bière, onctuosité d'une sauce, fraîcheur d'un épiderme féminin) stimule, dans sa représentativité, directement notre désir au lieu de se limiter à dénoter « glace », « sauce » ou « douceur » (ECO, La structure absente, p. 240). L'image des aliments fait l'objet d'une production éditoriale foi-sonnante, protéiforme : livres de cuisine, de recettes ; ouvrages sur le goût, la table, la gastronomie, les Chefs, les styles et les cultures aliment…

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…

Figuration of Taste and Web-design of Flavor Between Aesthesia and Aesthetics

2012

International audience; Figuration du goût et webdesign de la saveur, entre esthésie et esthétique 영어 초록 목차 û é ééé 키워드Solid relationships between aesthetics and ethics are always discussed, as so are many complex ramifications between the sensible and the intelligible. The question comes to enrich a third term which is often set back from these basic polarities: the aesthesia, the world of the senses, sensations, which are intended to cooperate. Schematically, it creates a fundamental relationship among aesthesia (sensations), aesthetic (forms) and ethics (values), which governs the approach of the sensible world and directs a complex issue such as the representation taste, the taste sensa…

Espresso ma non troppo. Del tempo y la lentitud en el ritual del café

2012

In the semiotic and communicational perspective retained for this article, the trinity of the sensitive world is organized around three polarities: aesthesia and synesthesia, in the registry of the sensory expression, esthetic regarding the forms and figures that give body to a sensitive experience, ethics regarding the way of life that is projected or updated in said experience. Applied to the degustation of coffee, their representations and their constitution in ritualized sensitive practice, this approximation shows the strong orientation given by the slowed, even suspended, temporality of the café in the emergence of the values for the subject of the experience. This sensitive utterance…
