C2RMF
● Research and Restoration Centre
● Created in 1931● Mission to
scientifically study, document and preserve works of art from all French museums
EU Projects
● 11 projects within the ESPRIT, IMPACT, RAPHAEL, IST and e-CULTURE frameworks since 1989

Project Themes
● Advanced Digital Imaging● Image Analysis● 3D Imaging/Modeling● Technical Vocabularies and Ontologies● Database Management
Digital Imaging
● Large historical scientific photo-archive dating back to 1931
● NARCISSE project in 1989: scanning of photographic archives at 6,000 x 8,000 pixels
Multispectral Imaging
● VASARI project● 7 filter camera (400-700nm)● 10,000 x 10,000 pixel resolution● High colour accuracy of ~1dE in
CIEL*a*b* colour space● Custom image processing software,
VIPS, developed to handle large images – resused in subsequant projects
Multispectral Imaging
● CRISATEL project● Portable camera● Higher resolution
20,000 x 12,000 pixels
● Sweeping light system minimizes damage to painting
Multispectral Imaging
● 13 interferential dichroic filters 400nm - 1000nm
Spectral Reconstruction
● Pigment Identification
● Illuminant simulation
3D Imaging
● ACOHIR project● Panoramic view● Colour calibrated
Panoramic Sequences
● Visible panorama● X-ray panorama
3D Modeling
● SCULPEUR project● Hardware from ACOHIR● Volumetric mapping via silhouette
extrusion
High Definition Models
3D Scanning of Paintings
● Laser-based
3D Scanning of Paintings
Visualization
● VISEUM project● Exchange of images
between institutions● Tiled Pyramidal TIFF● Client only requests
viewable area● Tiles dynamically JPEG
compressed and then sent to viewer
● Fast viewing with low memory requirements
How it works
How it works
Content Based Retreival
● ARTISTE project● Image recognition● Classification by colour coherence, spatial
distribution etc● Possible Uses:
Correlate artists to colours used or shapes Analysis of artist styles Technique analysis eg knife, brush Inscription characterisation eg signatures, motifs Ageing features eg lacuna, cracks, repaints
● Extended to 3D models in SCULPTEUR project
Ontologies & Semantic Web
● NARCISSE – first database● CRISTAL – technical vocabulary definitions
and translations into 10 languages● SCULPTEUR – CIDOC mapping
Project Fusion
● Bring project results together● EROS Multilingual and semantically
mapped Database● Remote viewing of
multispectral images 3D panoramas 3D models
● Search by image similarity● Database itself becomes a scientific
tool for original research
EROS Database
20,000 paintings
40,000 objects
10,000 reports, articles etc
15,000 chemical analyses
Dissemination
● Open Source software licenced under GPL where possible
● Allows the work to live on after end of project
● VIPS Image processing http://vips.sf.net
● IIPImage Remote visualization http://iipimage.sf.net
