Skeleton-Based Multiview Reconstruction
2016
International audience; The advantage of skeleton-based 3D reconstruction is to completely generate a single 3D object from well chosen views. Having numerous views is necessary for a reliable reconstruction but projections of skeletons lead to different topologies. We reconstruct 3D objects with curved medial axis (whose topology is a tree) from the perspective skeletons on an arbitrary number of calibrated acquisitions. The main contribution is to estimate the 3D skeleton, from multiple images: its topology is chosen as the closest to those of the perspective skeletons on the set of images, which means that the number of topology changes to map the 3D skeleton topology to topologies on im…

Images - Computed tomography urographic appearance of traumatic rupture of renal cyst into the pyelocaliceal system.
2019
Spontaneous or traumatic rupture of renal cysts, documented by radiological imaging, occurs infrequently. The pathogenesis of a cyst rupture is still unclear, except when it has occurred following trauma or when the cyst has become infected. Imaging plays a crucial role in the diagnosis, management, surveillance, and choice of lesions that need treatment.
"De 1967 à 1989 des journées ordinaires de télévision", in Le Pajolec et Tillier (ed.)Des histoires, des images, Mélanges offerts à Myriam Tsikounas
2021
International audience; L'image, ou plutôt les images et les représentations, qu’elles soient matérielles ou mentales, sont au centre des essais réunis dans ce volume, qui couvre un vaste domaine allant du cinéma soviétique aux addictions, des imaginaires parisiens aux feuilletons télévisés, des figurations du crime aux mises en scène de l’histoire, et s’articule autour d’une même notion, celle de « circulations ».
Social Media as Platform for Stimulating Urban Changes
2016
Images have always been an important part of city planning – current images of place, images with planned improvements, maps and sketches. Some time ago all that was a private property of stakeholders like planner and client. But nowadays this confidentiality rather much has vanished – no copyrights or competition is noteworthy. Plans do not have their privacy anymore. They are exposed even before they got implemented. This article will display why city planners share the images of their ideas, of their dreams in public (mostly in blogs and social networks) – why it is important for them and what kind of feedback they are waiting for. This article is based on case study where 12 respondents…
The Networked Utilisation of Satellite Images and Geospatial Technology in Journalism
2022
Satellite technology has become increasingly affordable and accessible in the past few decades. This has enabled many newsrooms to engage with genuinely remote journalism. This chapter explores the networked nature of satellite journalism and investigates its inclusion of experts and citizens outside newsrooms. Satellite journalism uses satellite-borne technology either as a (1) part of storytelling or (2) source of information. Academic research on the topic is scarce, so this chapter builds a base of knowledge on the contemporary practices, limitations and ethics—as well as directions of future development—of satellite journalism. By interviewing six journalists and one earth observation …

Conception en technologie CMOS d'un Système de Vision dédié à l'Imagerie Rapide et aux Traitements d'Images
2008
Our work presented in this thesis focuses on the design, testing and implementation of monolithics CMOS image smart sensors : The principle, performance and limitations. The hardware implementation of a vision smart system is the central link. HISIC is High Speed Image Capture with processing at pixel level. An experimental platform for instrumentation and evaluation of retina operators was conducted during this thesis. After a state of the smart sensors and CMOS retinas, the second part is dedicated to the study and design of the pixel image sensor HISIC. Two circuits were realized in CMOS technology. The first identied a new type of photo-detector, and the second, to create a prototype em…
Sélection de bandes pour la visualisation d'images spectrales : une approche basée sur l'étude de saillance
2011
National audience; De nos jours, la plupart des technologies d'affichage numériques sont basées sur le paradigme qu'une combinaison de trois couleurs primaires spécifiques est suffisante pour la reproduction d'une couleur quelconque pour l'oeil humain. Par ailleurs, les dispositifs d'affichage multispectraux ne sont pas encore monnaie courante sur le marché du multimédia. Ainsi, lorsqu'il s'agit de visualiser une image spectrale en couleur, sur un écran traditionnel, seuls trois bandes peuvent être utilisées simultanément, ce qui implique une réduction de dimensionnalité. Cette étape doit permettre la préservation d'un maximum de contenu informatif tout en préservant contrastes et couleurs …
Palermo e la guerra. Narrazioni: dalle immagini alle proposte di rinnovamento urbano
2023
The images of the bombing in Palermo in May 1943 are still etched in the collective memory. Some of the lacerations caused by the bombs are still clearly visible in the historic city centre, which has been the subject, since the post-war period, of numerous proposals that have remained in the drawer, images of an ethical and civil responsibility that has remained unheard. Old images of war and maps of ideas intersect in a history only apparently concluded in which they become generators of meaning and also bearers of messages relating to a desire for renewal.
