Session 1: 3D Data Acquisition and Archiving
Thursday, June 19
14:00-15:30 / Coffee break - Museum visit / 16:15-18:00
- Micro CT-scan: examples of fossil images; what can be seen? What are the differences with classic CT-Scan? What are the practical problems to process such data (i.e. memory space)?
- Talk: Bone microarchitecture scanners - MicroCT - XtremeCT (presentation in pdf), Audrey Berthier, Biomedical Engineer, MEDES - Institute For Space Physiology and Medicine, Toulouse , France
- Demo: Micro-CT of fossils, José Braga, Professor, Laboratory of Anthropobiology, FRE2960, Toulouse, France
- The human odyssey revisited by space technology (Web site).
- 3D surface scan: this technology is widely used (e.g. Minolta Vivid) and new devices which are less costly, more precise andtransportable have been made available these last years; examples of new devices; what are the practical problems (registering the different views, resolution of the texture); how is it possible to align 3D surface scan with 3D volume data?
- Talk: ARCHEOGRID: a National Conservatory of 3D Data of Cultural Heritage, Robert Vergnieux, Head of the 3D Technology Platform, Institut Ausonius, UMR5607, Pessac, France
- Demo: 3D surface scan of teeth, Tijani Gharbi, Professor ; Imen El Echmi, Ph.D. Student, FEMTO-ST Institute, UMR6174, Besançon, France
- 3D modelling of artifacts: how to acquire the 3D geometry of artifacts (stone tools, material art) ? How to analyze them?
- Talk: 3D modelling of prehistoric stone tools - state of the art and comparative study (presentation in pdf), Quentin Borderie, ArScAn, UMR7041, Paris, France
- Demo: CT, micro CT and surface scan of a "bâton percé" (presentation in pdf), Francis Duranthon, Curator, Museum of Natural History, Toulouse, France ; Ludovic Brethes, Scientific Director, Noomeo, Toulouse, France ; Gérard Subsol, Senior Researcher, ICAR Team, LIRMM, UMR5506, France
- Q. Borderie, P. Torguet, G. Subsol, H. de Lumley, B. Mafart, A. Vigouroux, J.P. Jessel. "3D Modeling of Paleolithic Tools". Workshop on Archaeology and Computers, Vienna (Austria), November 2004 (abstract in pdf).
- Archiving concerns: the digital format allows to exhange easily data by disks or through Internet. This opens new problems in terms of data integrity and copyrights.
- Talk: Watermarking 3D images and 3D meshes: Applications for cultural heritage (presentation in pdf), William Puech, Assistant Professor, Head of the ICAR Team, LIRMM UMR5506, Montpellier, France
- P. Amat, W. Puech, S. Druon and J.P. Pedeboy. "Data Hiding Method Based on the Topology Change of a 3D Triangular Mesh" in 15th European Signal Processing Conference, 2007 (text in pdf).
- W. Puech, G. Coatrieux. "Chapter 10: Coding: Encryption-Watermarking-Compression for Medical Information Security" in "Compression of Biomedical Images and Signals", Digital Signal Processing, ISTE-Wiley, 2008.
The session will be ended by a round-table where discussion between the all the participants will be encouraged.
