    • Documentation and Interpretation of an Archeological Excavation: an Experience with Dense Stereo Reconstruction Tools 

      Callieri, Marco; Dell'Unto, Nicolò; Dellepiane, Matteo; Scopigno, Roberto; Soderberg, Bengt; Larsson, Lars (The Eurographics Association, 2011)
      An archeological excavation is usually a rapidly evolving environment: several factors (weather, costs, permissions) force the work to be concentrated in a few weeks. Moreover, excavating is essentially a mono-directional ...
    • The Digital 3D Survey as Standard Documentation of the Archaeological Stratigraphy 

      Fiorini, Andrea; Urcia, Alberto; Archetti, Valentina (The Eurographics Association, 2011)
      In this contribution we describe tools and methods used to perform three-dimensional photogrammetric survey of different archaeological contexts. In particular, we studied in depth some aspects: swiftness (of the proceeding), ...
    • Linking Evidence with Heritage Visualization using a large Scale Collaborative Interface 

      Bale, Kim; Abbott, Daisy; Gowigati, Ramy; Pritchard, Douglas; Chapman, Paul (The Eurographics Association, 2011)
      The virtual reconstruction of heritage sites and artefacts is a complicated task that requires researchers to gather and assess many different types of historical evidence which can vary widely in accuracy, authority, ...
    • Preserving the Khmer Smile: Classifying and Restoring the Faces of Bayon 

      Lu, Min; Zheng, Bo; Takamatsu, Jun; Nishino, Ko; Ikeuchi, Katsushi (The Eurographics Association, 2011)
      The Bayon temple is known for its numerous massive stone faces with serene smiles, often referred to as the 'Khmer Smile.' Many of these sculptures are, however, only partially preserved, making it difficult to see the ...
    • Reconstructing and Exploring Massive Detailed Cityscapes 

      Gobbetti, Enrico; Marton, Fabio; Benedetto, Marco Di; Ganovelli, Fabio; Bühler, Matthias; Schubiger, Simon; Specht, Matthias; Engels, Chris; Gool, Luc Van (The Eurographics Association, 2011)
      We present a state-of-the-art system for obtaining and exploring large scale three-dimensional models of urban landscapes. A multimodal approach to reconstruction fuses cadastral information, laser range data, and oblique ...
    • Reassembling Thin Artifacts of Unknown Geometry 

      Oxholm, Geoffrey; Nishino, Ko (The Eurographics Association, 2011)
      We introduce a novel reassembly method for fragmented, thin objects that uses minimal user interaction. Unlike past methods, we do not make any restrictive assumptions about the geometry or texture of the object. To do so, ...
    • Integrated High-Quality Acquisition of Geometry and Appearance for Cultural Heritage 

      Schwartz, Christopher; Weinmann, Michael; Ruiters, Roland; Klein, Reinhard (The Eurographics Association, 2011)
      Current research trends demonstrate that, for a wide range of applications in cultural heritage, 3D shape acquisition alone is not sufficient. To generate a digital replica of a real world object the digitized geometric ...
    • Fast and Robust Semi-Automatic Registration of Photographs to 3D Geometry 

      Pintus, Ruggero; Gobbetti, Enrico; Combet, Roberto (The Eurographics Association, 2011)
      We present a simple, fast and robust technique for semi-automatic 2D-3D registration capable to align a large set of unordered images to a massive point cloud with minimal human effort. Our method converts the hard to solve ...
    • Radiometric Characterization of Spectral Imaging for Textual Pigment Identification 

      Kim, Min H.; Rushmeier, Holly (The Eurographics Association, 2011)
      Digital imaging of cultural heritage artifacts has become a standard practice. Typically, standard commercial cameras, often commodity rather than scientific grade cameras, are used for this purpose. Commercial cameras are ...
