Des os dans les fossés et des animaux dans les enclos : diversité des fonctions et limites des interprétations
1999
Des animaux vivants ont pu sejourner de maniere temporaire ou permanente dans certaines des enceintes qui parsement la Gaule au deuxieme Âge du Fer. Mais ils ont pu egalement y etre mis mort, manges ou abandonnes a la decomposition. La diversite des fonctions qu'ont pu remplir les enclos vis-a-vis de l'elevage et de l'usage des animaux est grande. Notre propos est d'essayer de voir dans quelle mesure il est possible de les restituer, et quels indices peuvent nous aider dans cette demarche.
Deep learning to detect built cultural heritage from satellite imagery. - Spatial distribution and size of vernacular houses in Sumba, Indonesia -
2021
Abstract In Sumba Island – Indonesia, the implantation of vernacular houses, inside and outside traditional villages, is considered to be an efficient proxy for the on-going complex cultural transformations resulting from globalization. This study presents an easily reproducible workflow allowing buildings to be automatically detected from satellite imagery, demonstrating how modern computer vision methods based on deep learning can help in this task, which would be far too time-consuming when undertaken by hand. Eight deep learning architectures based on convolutional neural networks were compared in terms of ability to identify and locate precisely traditional houses from satellite images…
Documenting carved stones from 3D models. Part II - Ambient occlusion to reveal carved parts.
2021
10 pages; International audience; Revealing carved parts in rock art is of primary importance and remains a major challenge for archaeological documentation. Computational geometry applied to 3D imaging provides a unique opportunity to document rock art. This study evaluates five algorithms and derivatives used to compute ambient occlusion and sky visibility on 3D models of Mongolian stelae, also known as deer stones. By contrast with the previous companion work, models are processed directly in 3D, without preliminary projection. Volumetric obscurance gives the best results for the identification of carved figures. The effects of model resolution and parameters specific to ambient occlusio…
A laboratory cave for the study of wall degradation in rock art caves : an implementation in the Vézère area
2013
The aim of this proposal is to present an original approach to the study and preservation of rock art caves. A multidisciplinary study of cave wall alteration will be performed to understand the impact of environmental context on the evolution of wall surfaces. The approach involves the choice of a cave with characteristics similar to painted caves in the studied area (Vézère Valley in Dordogne, France): e.g., cave wall alteration, lithology, morphology, etc. This selected cave is intended to become a laboratory cave, monitored for the acquisition of chemical, physical and biological environmental data on bedrock, air and fluids along with their characteristics. A cave without art or archae…

Major palaeohydrographic changes in Alpine foreland during the Pliocene - Pleistocene
2008
International audience; The changing palaeogeographical pattern of Alpine deposits across the European forelands can be traced by identifying mineral assemblages and establishing the chronology of Pliocene-Pleistocene deposits in Alpine foreland. In the late Miocene, the upper courses of the Rhine and the Aar flowed east from the Swiss molasse plain towards the Danube. In the early Pliocene (Brunssumian, 5-3.2 Ma), these same rivers headed north-wards towards the Rhine Graben of Alsace. In the early Reuverian, these streams were captured south of the Rhine Graben by the Doubs. They ceased their northward flow and headed west to feed the Bresse Graben. This phase is dated to the Lower and Mi…
La prehistoria de Ibiza y Formentera: estado actual de la investigación
1988
The study of the prehistory of Ibiza and Formentera, the two small islands that form the Pityussae sub-group within the Balearic archipelago, began a few years ago as a consequence of the discovery and excavation of the megalithic chamber tomb of a Ca Na Costa on Formentera. Before then, prehistorians were still in doubt as to whether these islands had been occupied before the Phoenician colonisation. Many sites have come to light in the last decade, allowing us to present for the first time a general survey of the prehistoric settlement of the islands. Nevertheless, many problems are still unsolved, and new excavations are needed to establish the apparently complex cultural sequence, which…
