Une mariophanie martiale à Dijon
2015
The ”delivrance de Dijon” in 1513 is an ambiguous event that mixes original procession, memorial procession, votive tapestry and historiographical interpretation. This paper studies, in this ”millefeuille”, the uses of martial miracle of the Virgin Mary in favor of Dijon inhabitants. What is the role of these invocation-purposed processions in the panic context of war and in the Marian piety of the Burgundian renaissance ? The Mariophany of the delivrance must not be interpreted in the light of negotiations between the city and the besiegers and a treaty that saves the city and its inhabitants, but sees Louis XII unhappy ? Finally, doesn’t divine intervention result from the power of the im…
Application of LSTM architectures for next frame forecasting in Sentinel-1 images time series
2020
L'analyse prédictive permet d'estimer les tendances des évènements futurs. De nos jours, les algorithmes Deep Learning permettent de faire de bonnes prédictions. Cependant, pour chaque type de problème donné, il est nécessaire de choisir l'architecture optimale. Dans cet article, les modèles Stack-LSTM, CNN-LSTM et ConvLSTM sont appliqués à une série temporelle d'images radar sentinel-1, le but étant de prédire la prochaine occurrence dans une séquence. Les résultats expérimentaux évalués à l'aide des indicateurs de performance tels que le RMSE et le MAE, le temps de traitement et l'index de similarité SSIM, montrent que chacune des trois architectures peut produire de bons résultats en fon…
An SVD-Based Approach for Ghost Detection and Removal in High Dynamic Range Images
2012
International audience; In this paper, we propose a simple method for the ghost detection problem in the context of merging multiple low dynamic range (LDR) images to form a high dynamic range (HDR) image. We show that the second biggest singular values extracted over local spatio-temporal neighbourhoods can be effectively used for ghost region detection. Furthermore, we combine the proposed method with an exposure fusion technique to generate final HDR image free of ghosting artefacts. We present experimental results to illustrate the efficiency of the proposed method and quantitative comparison with other existing approaches show the good performance of our method in detecting and removin…
Statistical atlas based exudate segmentation
2013
International audience; Diabetic macular edema (DME) is characterized by hard exudates. In this article, we propose a novel statistical atlas based method for segmentation of such exudates. Any test fundus image is first warped on the atlas co-ordinate and then a distance map is obtained with the mean atlas image. This leaves behind the candidate lesions. Post-processing schemes are introduced for final segmentation of the exudate. Experiments with the publicly available HEI-MED data-set shows good performance of the method. A lesion localization fraction of 82.5% at 35% of non-lesion localization fraction on the FROC curve is obtained. The method is also compared to few most recent referen…

Undercurrents and crosscurrents revealed: Sinéad Morrissey’s parallactic poetry
2015
International audience; In Parallax (2013), her most recent collection of poems, Sinéad Morrissey is attracted to affections “embedded in our cells”, to realities “on the periphery”, to “what happens outside”, to “the accidental”, to “world[s] that can’t be entered”, to “conversation[s] no one else can hear”. She also explores oblique, alternative perspectives that she describes in “The Mutoscope” as “what-the-butler-saw perspective[s]”. Parallax – the optical phenomenon used in astronomy to measure the distance of nearby stars and celestial bodies - serves as the prime metaphor for Morrissey’s poetical and metaphysical quest: the implications of the angle of vision and distance on percepti…
