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…
SUÁREZ-GUERRERO, C.; MARÍN-SUELVES, D. y PALOMARES-MONTERO, D. (2016) Retos de la educación en tiempos de cambio. Valencia, Tirant Humanidades.
2017
El sistema educativo debe hacer frente a los continuos cambios que se producen en nuestra sociedad. Cambios que afectan a las estructuras sociales y las relaciones y que, por lo tanto, interfieren directamente en la práctica educativa. Por esta razón, el libro Retos de la educación en tiempos de cambio ofrece un espacio de reflexión sobre los desafíos educativos que permitirán contribuir a la renovación de la escuela mediante un discurso inclusivo que favorezca una cultura democrática y participativa.
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…
Community planning e community visioning. Visioni e scenari dal basso come “progetto tentativo” per riequilibrare spazio e società e ricostruire terr…
2017
Già dalla seconda metà degli anni 60 del secolo scorso in Italia, alcuni urbanisti (e non solo se si pensa alla poliedrica attività di Adriano Olivetti) incoraggiavano nuove metodologie di costruzione degli spazi urbani e territoriali mediante il recepimento della domanda sociale attraverso le pratiche di partecipazione degli abitanti alle scelte di governo del territorio. Tutto ciò avveniva sulla scia dell’advocacy planning molto in voga negli states, lanciato nel decennio precedente, ma anche dalla contaminazione del “situazionismo internazionale” principalmente di derivazione francese. Così dal nord al sud del nostro Paese, dalla scala urbana a quella territoriale, alcuni pionieri del ri…
Mitä rehtorit todella tekevät : etnografinen tapaustutkimus johtamisesta ja rehtorin tehtävistä peruskoulussa
2007
Aarne Mäkelä tutki väitöstyössään peruskoulun johtamista ja rehtorin tehtäviä. Tutkimus osoitti, että rehtorin tehtävät ovat muuttumassa. - Pitkän johtajakokemukseni aikana olen tunnistanut, että johtaminen on muuttunut, mutta muutoksen voimakkuus oli yllättävää. Erityisesti koulun selkärankana pidetyn pedagogisen johtamisen tehtäväalueen vähäinen osuus huolestuttaa, toteaa Mäkelä. Mäkelä osoitti, että nykyään rehtori joutuu entistä enemmän hoitamaan koulun yhteistyöverkostoihin liittyviä tehtäviä. Tällaisia ovat mm. lasten huoltajien, perhekotien, kiinteistönhuollon, sosiaali- ja terveysviranomaisten, pelastus- ja turvallisuusviranomaisten sekä muiden koulun sidosryhmien kanssa tehtävä ver…
Lectio praecursoria: (Re)Imagining Humanity in Popular Science Fiction Television
2015
Aino-Kaisa Koistinen (PhD in spe) defended her doctoral dissertation The Human Question in Science Fiction Television: (Re)Imagining Humanity in Battlestar Galactica, Bionic Woman and V at the University of Jyvakyla, Finland on the 11th of April 2015. This essay is a slightly edited version of the lectio praecursoria given by Koistinen before the defense. nonPeerReviewed
Economic Double Censorship
2020
This chapter explores the censorship impact generated by economic logic on the selection and coverage of topics in factual formats and current affairs documentaries on French television. This prelimina- ry research studies more specifically the subcontracting relationships between TV channels and production companies from semi- structured interviews with various categories of professionals (managers of TV press agencies, journalists, directors, Commissioning Editor). The analysis distinguishes two types of censorship ef- fects. The competitive relationships and the business models of the broadcasters condition their positions in the media field and thus exercise a structural censorship on t…
Automated Detection of Microaneurysms Using Scale-Adapted Blob Analysis and Semi-Supervised Learning
2014
International audience; Despite several attempts, automated detection of microaneurysm (MA) from digital fundus images still remains to be an open issue. This is due to the subtle nature of MAs against the surrounding tissues. In this paper, the microaneurysm detection problem is modeled as finding interest regions or blobs from an image and an automatic local-scale selection technique is presented. Several scale-adapted region descriptors are then introduced to characterize these blob regions. A semi-supervised based learning approach, which requires few manually annotated learning examples, is also proposed to train a classifier to detect true MAs. The developed system is built using only…
