Germigny-des-Prés – Place du Bourg
Le site de Germigny-des-Prés abrite une des plus anciennes églises de France. Initialement bâtie par Théodulfe (v. 760-821), elle a été classée Monument Historique sur la première liste de 1840. Les recherches récentes sur Germigny-des-Prés concernent les sources textuelles relatives à l’église et son degré d’authenticité, Théodulfe, son œuvre et sa personnalité, de même que les décors de l’oratoire. Des prospections par radar-sol ont également été réalisées aux alentours de l’édifice. Ces re..

Renouvellement des constructions religieuses et élite carolingienne
Les sites de Germigny-des-Prés La construction de l’oratoire de Germigny (Loiret) est attribuée par les sources à l’abbé de Saint-Benoit-sur-Loire, et évêque d’Orléans Théodulphe (v. 760-821), sur une dépendance du monastère de Fleury dont il est l’abbé (798-818). Elle serait le seul vestige d’un complexe résidentiel plus vaste. L’oratoire aurait été consacré en 806. Classée Monument Historique sur la première liste de 1840, l’ancienne église de Germigny a été l’objet de restaurations importa..
TESSERAE3D : Une comparaison pour la segmentation sémantique des tesselles dans les nuages de points 3D
3D point cloud of mosaic tesserae is used by heritage researchers, restorers, and archaeologists for digital investigations. Information extraction, pattern analysis, and semantic assignment are necessary to complement geometric information. Automated processes that can speed up the task are highly sought after, especially new supervised approaches. However, the availability of labeled data necessary for training supervised learning models is a significant constraint. This paper introduces Tesserae3D, a 3D point cloud benchmark dataset for training and evaluating machine learning models, applied to mosaic tesserae segmentation. It is a publicly available, very high density and colored dataset, accompanied by a standard multi-class semantic segmentation baseline. It consists of about 502 million points and contains 11 semantic classes covering a wide range of tesserae types. We propose a semantic segmentation baseline building on radiometric and covariance features fed to ensemble learning methods. The results delineate an achievable 89% F1 score and are made available under https://github.com/akharroubi/Tesserae3D, providing a simple interface to improve the score based on feedback from the research community

Céramiques et verres mérovingiens dans la vallée mosane. Apports de l'archéologie et de l'archéométrie à l'histoire économique, sociale et culturelle.
Thank to an interdisciplinary approach involving archaeology and scientific analysis, Merovingian ceramic and glass found in the Meuse-valley have been studied. This approach allowed us to elaborate a typochronology for these type of artifact and moreover to shed some light on the history of craft, economic aspects and the cultural impregnations of this particular time. Aside from the darkness that can be associated to this period, Merovingian craftmen still mastered specific skills and technological evolutions took place. Until the middle of the VIth century, trade networks were not abandoned. For glass production, raw material seems to be imported from Mediterranean regions and glass final products as well as clay vessels were still exported at a regional scale. Between the end of the VIth and the VIIth century, glass becomes rare and new types of ceramic locally made appears. In cemeteries, living settlements and productions sites, both crafts underline economical and cultural modifications in the Meuse-valley. Finally, at the end of the Merovingian period, ceramic and glass reflect new consumption’s behavior that came into sight announcing the transition to the Carolingian world
