Picturing Dorian Gray: Portrait of an Adaptation
2016
The Picture of Dorian Gray constitue un sujet de choix pour les cineastes, et ce, pour de nombreuses raisons : il s’agit d’un conte moral captivant, dote d’une intrigue qui regorge de beaute, d’amour et d’action ; c’est un exemple celebre de texte victorien influence en partie par le roman « gothique ». Le roman de Wilde a ainsi inspire de nombreuses generations de cineastes. Toutefois, cette œuvre pose aux realisateurs des problemes particuliers, dont un est suggere par le titre meme de l’ouvrage : comment representer le portrait extraordinaire de Dorian Gray a l’ecran, tant dans sa beaute eclatante initiale que dans ses metamorphoses monstrueuses ? Chacune des adaptations etudiees dans ce…
Quand l'école se mobilise
2002
International audience; Cet ouvrage analyse les effets des politiques de démocratisation et de décentralisation sur l'organisation interne des établissements d'enseignement et sur le rapport au métier des professionnels de l'éducation. L'importance des transformations constatées dépend de la capacité des enseignants à adapter leurs pratiques et leurs éthiques professionnelles aux caractéristiques sociales et scolaires des élèves, sans renoncer à leurs exigences. Elle repose aussi sur des dynamiques collectives impliquant solidairement les diverses catégories de personnels. La mobilisation de l'école apparaît ainsi au carrefour d'une prise en compte des contraintes locales et d'une volonté c…

A Continuous Time Pattern Recognition Retina
2002
International audience; We present in this paper a pattern recognition retina operating in continuous time. During a programming phase, the reference image is acquired by the sensor. After thresholding, the resulting binary image is stored in the sensor's pixels. During the recognition phase, the retina calculates, in an analog way and in continuous time, the zero displacement intercorrelation of the current image with the binary reference image and its complement. These two intercorrelation values are output as currents. By comparing these currents to expected values, determined during the programming phase, a shift of the pattern or a difference between the observed and programmed pattern…
Optimal Gabor Filters and Haralick Features for Industrial Polarization Imaging
2011
International audience; During the past decade, computer vision methods for inline inspection became an important tool in a lot of industrial processes. During the same time polarization imaging techniques rapidly evolved with the development of electro-optic components, as e.g. the polarization cameras, now available on the market. This paper is dedicated to the application of polarization techniques for visually inspecting complex metallic surfaces. As we will shortly recall, this consists of a direct image interpretation based on the measurement of the polarization parameters of the light reflected by the inspected object. The proposed image interpretation procedure consists of a Gabor p…
Temporal-range estimation of multiple objects: evidence for an early bottleneck.
2011
When making parallel time-to-contact (TTC) estimates of two approaching objects, the two respective TTC estimates interfere with one another in an asymmetric fashion. The TTC of the later-arriving object is systematically overestimated, while the estimated TTC for the first-arriving object is as accurate as in a condition presenting only a single object. This asymmetric interference points to a processing bottleneck that could be due to early (e.g., during the estimation of the TTC from the optic flow) or late (e.g., during the timing of the response or the motor execution) constraints in the TTC estimation process. We used a Sperling-like prediction-motion task to differentiate between the…
Combining omnidirectional vision with polarization vision for robot navigation
2012
Polarization is the phenomenon that describes the oscillations orientations of the light waves which are restricted in direction. Polarized light has multiple uses in the animal kingdom ranging from foraging, defense and communication to orientation and navigation. Chapter (1) briefly covers some important aspects of polarization and explains our research problem. We are aiming to use a polarimetric-catadioptric sensor since there are many applications which can benefit from such combination in computer vision and robotics specially robot orientation (attitude estimation) and navigation applications. Chapter (2) mainly covers the state of art of visual based attitude estimation.As the unpol…

L'équipe de casting pour Notre pain quotidien : le blé. Réalisateur : Alexandre Largeron • Emilie Darnaud Société de Production Miss Luna Films • Ushuaïa TV A l'origine même de l'agriculture, le blé est, après des millénaires, la première plante cultivée au monde et l'aliment de base du tiers de la population mondiale.Sa production annuelle dépasse les 700 millions de tonnes soit près de 100 kg par habitant. En France, 1er pays producteur d'Europe, le blé tient une place majeure dans la filière agricole mais aussi dans notre culture.Dans ce film, nous suivrons plusieurs exploitants durant leurs moissons, de la récolte vers la transformation, et jusqu'à sa commercialisation.

Multi-Scale Feature Extraction for Vehicle Detection Using Phis-Lbp
2018
International audience; Multi-resolutionobjectdetectionfacesseveraldrawbacksincludingitshighdimensionalityproducedby a richer image representation in different channels or scales. In this paper, we propose a robust and lightweight multi-resolution method for vehicle detection using local binary patterns (LBP) as channel feature. Algorithm acceleration is done using LBP histograms instead of multi-scale feature maps and by extrapolating nearby scales to avoid computing each scale. We produce a feature descriptor capable of reaching a similar precision to other computationally more complex algorithms but reducing its size from 10 to 800 times. Finally, experiments show that our method can obt…
