Fornaci e produzioni del Golfo di Castellamare (Sicilia nord-occidentale)
2020
L’area del Golfo di Castellammare (Sicilia occidentale) è nota per le numerose fornaci di età romana. In questo articolo, si cercherà di ricostruire l’attività di un’officina destinata principalmente alla produzione di laterizi con bollo ΟΝΑΣΟΥ, databile fra III e I secolo a.C. Ricerche precedenti hanno permesso di riconoscere nel produttore di questi laterizi lo stesso Onasus Segestanus citato nelle Verrine di Cicerone e di localizzarne una possibile officina presso la Baia di San Cataldo. La scoperta di nuovi laterizi bollati e di scarti ceramici assume notevole importanza per una ricerca sugli ateliers ceramici del Golfo di Castellammare e della Piana di Partinico. Ne deriva un quadro ag…

A detailed method for creating digital 3D models of human crania: an example of close‑range photogrammetry based on the use of Structure‑from‑Motion …
2022
AbstractPhotogrammetry is a survey technique that allows for the building of three-dimensional (3D) models from digitized output data. In recent years, it has been confirmed as one of the best techniques to build 3D models widely used in several fields such as life and earth sciences, medicine, architecture, topography, archaeology, crime scene investigation, cinematography, and engineering. Close-range photogrammetry, in particular, has several applications in osteological studies allowing to create databases of 3D bone models available for subsequent qualitative and quantitative studies. This work provides a step-by-step guide of the photo acquisition protocol and the photogrammetric work…
Les objets en plomb découverts sur le site portuaire médiéval de Taillebourg - Port d'Envaux : typologie, fonction et origine
2006
Des prospections subaquatiques menees dans la Charente, sur le site de Taillebourg – Port d’Envaux (17), ont revele la presence de nombreux temoins d’activites lies au fleuve Charente, dates principalement des periodes merovingienne et carolingienne. Parmi l’abondant mobilier decouvert figure un lot d’objets en plomb.Ces plombs ont ete trouves dans un contexte de pratiques halieutiques. Les premieres interpretations les definissent comme des lests d’engins de peche. La decouverte d’un tel corpus est deja en soi un fait interessant. En effet, la facilite de recyclage de ce materiau de plaide pas pour sa conservation. L’etude de ce materiel a porte a la fois sur la definition de leur typologi…
Die jungbronzezeitliche Außensiedlung der „Hünenburg“ bei Watenstedt, Lkr. Helmstedt. Vorbericht über die Ausgrabungen 2005–2007
2010
Le Harz septentrional, le contrefort le plus au nord des massifs hercyniens europeens, compte plusieurs habitats de hauteur fortifies sur le territoire du groupe de Saalemundung. Ces dernieres annees, on a pu intensifier les recherches archeologiques menees autour du site fortifie de hauteur l'Hunenburg, situe au nord-ouest pres de Watenstedt (Lkr. Helmstedt). Les ramassages de surface juste au sud de l'enceinte du site, les prospections geomagnetiques, ainsi que les premieres fouilles qui suivirent, deboucherent sur la decouverte d'une agglomeration exterieure contemporaine, qui couvre jusqu'ici 5,5 ha et dont les limites restent a decouvrir. Les fouilles ont revele les premiers plans de m…

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…
