Profiling of new Europeans in the British conservative press : a case study of the "Daily Telegraph"
2017
This chapter presents an exploratory analysis of discursive strategies through which Europe and Europeans are represented, focusing on how their images are profiled in the texts of the British conservative newspaper Daily Telegraph, a quality newspaper ranked as one of the three most widely read in the UK throughout the 2000s. We explore articles retrieved from the Internet version of the Daily Telegraph from the 1st of May, 2004 to the 1st of May, 2009, aiming to establish the patterns of distribution of the words “EU”, “Europe” or “European”, and discover possible othering techniques that do not overtly transgress the rules of political correctness. Such covert profiling, among other fact…
Fusion of computed point clouds and integral-imaging concepts for full-parallax 3D display
2020
During the last century, various technologies of 3D image capturing and visualization have spotlighted, due to both their pioneering nature and the aspiration to extend the applications of conventional 2D imaging technology to 3D scenes. Besides, thanks to advances in opto-electronic imaging technologies, the possibilities of capturing and transmitting 2D images in real-time have progressed significantly, and boosted the growth of 3D image capturing, processing, transmission and as well as display techniques. Among the latter, integral-imaging technology has been considered as one of the promising ones to restore real 3D scenes through the use of a multi-view visualization system that provi…
Integration of large-area optical imagers for biometric recognition and touch in displays
2021
In recent years there has been an increasing interest to integrate optical sensing in mobile displays, for instance, for biometric fingerprint scanning functionality. There are several routes to incorporate optical fingerprint functionality within the full display area, each with their own benefits and challenges. Here we investigate the different integration routes using large-area, ultra-thin imagers based on organic photodiodes.
A Dataset of Annotated Omnidirectional Videos for Distancing Applications
2021
Omnidirectional (or 360°) cameras are acquisition devices that, in the next few years, could have a big impact on video surveillance applications, research, and industry, as they can record a spherical view of a whole environment from every perspective. This paper presents two new contributions to the research community: the CVIP360 dataset, an annotated dataset of 360° videos for distancing applications, and a new method to estimate the distances of objects in a scene from a single 360° image. The CVIP360 dataset includes 16 videos acquired outdoors and indoors, annotated by adding information about the pedestrians in the scene (bounding boxes) and the distances to the camera of some point…
Nonlinear Time-Series Adaptation for Land Cover Classification
2017
Automatic land cover classification from satellite image time series is of paramount relevance to assess vegetation and crop status, with important implications in agriculture, biofuels, and food. However, due to the high cost and human resources needed to characterize and classify land cover through field campaigns, a recurrent limiting factor is the lack of available labeled data. On top of this, the biophysical–geophysical variables exhibit particular temporal structures that need to be exploited. Land cover classification based on image time series is very complex because of the data manifold distortions through time. We propose the use of the kernel manifold alignment (KEMA) method for…
Kroppsbilde og slankefokus blant fysisk aktive gutter i ungdomsskolen og på videregående skole i Norge :
2016
Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 The aim of this study was to investigate body image and drive for thinness among adolescent boys, and to examine variations for these variables in age and level of physical activity. This cross-sectional study is part of “the Relevance of Physical Activity Contexts in Every-Day Life of Adolescents” (REPAC), which is a larger project. 1423 boys from secondary school (8th grade) and upper secondary school (11th grade) were included in this study, and these responded to a questionnaire that was developed to examine how different activity contexts affected adolescent boys everyday lives. Correlation analysis and one-way ANOVA tests w…
Pitch tilt rendering for an 8-DOF driving simulator
2015
International audience; Tilt coordination technique is used for reproducing a sustained linear acceleration in driving simulation by tilting the simulator cabin. Thus a part of gravity is interpreted as a horizontal acceleration. Between the slow rotational motion limited by the rotational perception threshold of semi-circular canals of vestibular system and the fast change of acceleration to render, the design of coupling motions of rotation and translation plays a critical role in the realism of driving simulator. We present here an experiment focusing on longitudinal accelerations rendering with pitch tilt coordination technique. Eight drivers experienced the same accelerations and decel…
Graphic hyperboles and critical dystopia in Miguel Brieva's drawings
2020
Dorothée CHOUITEM, Louis IMPERIALE, Joanna WILK-RACIĘSKA (coord); International audience; Dans les dessins de Miguel Brieva (Séville, 1974), l’humour participe assurément d’un exercice de déconstruction. Critique, moqueur, destructeur, son geste graphique se complait dans la propension à l’exagération, à l’hyperbole et au « superlatif ». L’intention est de mettre au jour les nouvelles formes de violence de la période présente de l’hypercapitalisme. La félicité n’étant guère questionneuse, c’est le dessin, en tant qu’outil de monstration, qui sera chargé de présenter les contreparties de nos jouissances acquises. Les images auront ici pour ambition de participer au renversement des insoutena…
Towards Ecosystemic Stance in Finnish Public Sector Enterprise Architecture
2019
Governments and organizations in both public and private sector are operating in fields of ever-growing uncertainty and complexity. To study this complex environment, the concept of ecosystems has been suggested, interpreting organizations as intertwined systems among layers of evolving ecosystems. While offering possibilities, operating in an ecosystemic environment might prove to be challenging, and the change from traditional governance structures might be difficult to manage, requiring holistic yet detailed view. Enterprise Architecture (EA) has been an interest of academics and practitioners for few decades, offering one of the most prominent solutions to managing complex organizations…
Regularization Preserving Localization of Close Edges
2007
International audience; In this letter, we address the problem of the influence of neighbor edges and their effect on the edge delocalization while extracting a neighbor contour by a derivative approach. The properties to be fulfilled by the regularization operators to minimize or suppress this side effect are deduced, and the best detectors are pointed out. The study is carried out in 1-D for discrete signal. We show that among the derivative filters, one of them can correctly detect our model edges without being influenced by a neighboring transition, whatever their separation distance is and their respective amplitude is. A model of contour and close transitions is presented and used through…
