AN APPROACH TO CORRECTING IMAGE DISTORTION BY SELF CALIBRATION STEREOSCOPIC SCENE FROM MULTIPLE VIEWS
2012
International audience; An important step in the analysis and interpretation of video scenes for recognizing scenario is the aberration corrections introduced during the image acquisition in order to provide and correct real image data. This paper presents an approach on distortion correction based on stereoscopic self calibration from images sequences by using a multi-camera system of vision (network cameras). This approach for correcting image distortion brings an elegant and robust technique with good accuracy. Without any knowledge of shooting conditions, the camera's parameters will be estimated. For this, the image key points of interest are extracted from different overlapping views …
Painting the United States’ Civil War: Or creating a Brotherly War
2015
This article seeks to illustrate Benedict Anderson’s theory of the “Reassurance of Fratricide” and “the act of remembering/forgetting” through depictions of the Civil War in US fine arts. This is mostly done through the Smithsonian art data base and the paintings referenced under the label Civil War, spanning from the 1860s to the 1890s. This paper first analyzes how these paintings were used to depict the Confederate soldier’s otherness as typically American and thus helped with the post-war reintegration of the Confederacy. This study then examines how in certain paintings the war was brought inside the realm of domesticity and family, which reinforced the idea of a fratricide and a famil…

Overview paper: New insights into aerosol and climate in the Arctic
2019
Motivated by the need to predict how the Arctic atmosphere will change in a warming world, this article summarizes recent advances made by the research consortium NETCARE (Network on Climate and Aerosols: Addressing Key Uncertainties in Remote Canadian Environments) that contribute to our fundamental understanding of Arctic aerosol particles as they relate to climate forcing. The overall goal of NETCARE research has been to use an interdisciplinary approach encompassing extensive field observations and a range of chemical transport, earth system, and biogeochemical models. Several major findings and advances have emerged from NETCARE since its formation in 2013. (1) Unexpectedly high summer…
Decreasing Phanerozoic extinction intensity as a consequence of Earth surface oxygenation and metazoan ecophysiology
2021
The decline in background extinction rates of marine animals through geologic time is an established but unexplained feature of the Phanerozoic fossil record. There is also growing consensus that the ocean and atmosphere did not become oxygenated to near-modern levels until the mid-Paleozoic, coinciding with the onset of generally lower extinction rates. Physiological theory provides us with a possible causal link between these two observations-predicting that the synergistic impacts of oxygen and temperature on aerobic respiration would have made marine animals more vulnerable to ocean warming events during periods of limited surface oxygenation. Here, we evaluate the hypothesis that chang…
Mixed Driven Refinement Design of Multidimensional Models based on Agglomerative Hierarchical Clustering
2015
20 pages; International audience; Data warehouses (DW) and OLAP systems are business intelligence technologies allowing the on-line analysis of huge volume of data according to users' needs. The success of DW projects essentially depends on the design phase where functional requirements meet data sources (mixed design methodology) (Phipps and Davis, 2002). However, when dealing with complex applications existing design methodologies seem inefficient since decision-makers define functional requirements that cannot be deduced from data sources (data driven approach) and/or they have not sufficient application domain knowledge (user driven approach) (Sautot et al., 2014b). Therefore, in this p…
Une méthodologie et un outil pour le prototypage rapide des entrepôts de données en utilisant le data mining : application à la biodiversité des oise…
2014
International audience; Data Warehouses (DWs) are large repositories of data aimed at supporting the decision-making process by enabling flexible and interactive analyses via OLAP systems. Rapid prototyping of DWs is necessary when OLAP applications are complex. Some work about the integration of Data Mining and OLAP systems has been done to enhance OLAP operators with mined indicators, and/or to define the DW schema. However, to best of our knowledge, prototyping methods for DWs do not support this kind of integration. Then, in this paper we present a new prototyping methodology for DWs, extending [3], where DM methods are used to define the DW schema. We validate our approach on a real da…
Regional projection of winter frost risk on a legume crop due to warming in a temperate climate
2022
International audience; Pea (Pisum sativum L.) is an important annual legume crop grown in temperate regions for its high seed nitrogenconcentration and environmental benefits. In the recent climate warming, a subtle evolution of the winter cropfrost risk was observed: a paradoxical increase of frost stress events and a frost stress intensity decrease (Castel etal. 2017). Such results are questioning the future winter frost risk for peas. We assessed the winter frost damageevolution along 2006 to 2100 in Burgundy-Franche-Comté (a French region - western part of Europe). The approachis based on the combination of i) a dynamical downscaled climate data of two RCP trajectories (4.5 and 8.5) (B…
Environmental spillovers and their impacts on housing prices: A spatial hedonic analysis
2015
This paper investigates the spatial dimension of environmental factors on housing prices. We develop spatial hedonic models to estimate the implicit prices of various environmental attributes. The spatial dimension can be interpreted in terms of local or global spillovers. We conduct an empirical study in the Loire estuary (France). We focus on natural areas and more artificialized ones (ocean frontage, wetlands, rivers, and noisy roads). We show that, depending on the spatial model used, the implicit price is more than just the estimated coefficient value and combines both a feedback effect and a propagation effect.
Organisation médicale pendant la première guerre mondiale. L’exemple de l’hôpital américain de Saint-Parize-le-Châtel
2016
The data obtained from the diagnosis carried out in 2014 in Saint-Parize-le-Châtel, in Nievre, compared with those obtained from the archives and information provided by local authorities, enabled us to retrace the history of this large American hospital (700 permanent buildings on 330 ha) built during the winter of 1918-1919. The spatial organization of the camp, which meets various criteria (patient/caregiver, male/female, officers/soldiers, living areas/care areas/technical areas), and equipment (radiology, disinfection, laboratories...) show that it was conceived as a place benefiting from pioneering advances in matters of health.
