    • Earthquake Simulation for Ancient Building Destruction 

      Fita, Josep Lluis; Besuievsky, Gonzalo; Patow, Gustavo (The Eurographics Association, 2018)
      Research on seismic simulations has been focused mainly on methodologies specially tailored for civil engineering. On the other hand, we have detected a certain lack of this kind of tools for interactive cultural heritage ...

    • Elastic Flattening of Painted Pottery Surfaces 

      Preiner, Reinhold; Karl, Stephan; Bayer, Paul; Schreck, Tobias (The Eurographics Association, 2018)
      Generating flat images from paintings on curved surfaces is an important task in Archaeological analysis of ancient pottery. It allows comparing styles and painting techniques, e.g, for style and workshop attribution, and ...

    • Gloss Calibration and Gloss Gamut Mapping for Material Appearance Reproduction of Paintings 

      Elkhuizen, Willemijn S.; Essers, Tessa T. W.; Song, Yu; Pont, Sylvia C.; Geraedts, Jo M. P.; Dik, Joris (The Eurographics Association, 2018)
      Being able to link captured material characteristics and fabricable material appearance attributes is important for creating life-like reproductions. In this paper we propose a method for gloss calibration, and an approach ...

    • Granitic Recumbent Statue Reproduction by a Seven Axes Robotic Milling Machine 

      Barreau, Jean-Baptiste; Jouneau, Joëlle; Mérelle, Johnny; Maillard, Loïc; Bernard, Yann; Quesnel, Laurent (The Eurographics Association, 2018)
      Facing the sea, the rocks sculpted by the "Abbé Fouré" at the "Pointe du Christ" and the "Pointe de la Haie" in Rothéneuf (Brittany, France) attract many visitors. Winds, rains and sea spray erode each day a little more ...

    • An Image-based Approach for Detecting Faces Carved in Heritage Monuments 

      Lai, Yu-Kun; Echavarria, Karina Rodriguez; Song, Ran; Rosin, Paul L. (The Eurographics Association, 2018)
      Heritage monuments such as columns, memorials and buildings are typically carved with a variety of visual features, including figural content, illustrating scenes from battles or historical narratives. Understanding such ...

    • Improving Marker-Based Tracking for Augmented Reality in Underwater Environments 

      Cejka, Jan; Zuzi, Marek; Agrafiotis, Panagiotis; Skarlatos, Dimitrios; Bruno, Fabio; Liarokapis, Fotis (The Eurographics Association, 2018)
      Underwater sites are a challenging environment for augmented reality. Images taken under water are degraded in several ways, most importantly they are affected by unbalanced colors due to uneven absorption of light in each ...

    • Integrated Spatio-temporal Documentation and Analysis of Archaeological Stratifications Using the Harris Matrix 

      Neubauer, Wolfgang; Traxler, Christoph; Lenzhofer, Andreas; Kucera, Matthias (The Eurographics Association, 2018)
      The Harris Matrix (HM) is the fundamental diagrammatic representation of relative time for an archaeological site and the de facto standard for the representation of a stratigraphic sequence - the backbone for archaeological ...

    • Integrated Volume Visualisation of Archaeological Ground Penetrating Radar Data 

      Bornik, Alexander; Wallner, Mario; Hinterleitner, Alois; Verhoeven, Geert; Neubauer, Wolfgang (The Eurographics Association, 2018)
      The non-invasive prospection of our archaeological heritage is one of the main tasks of modern archaeology and often provides the necessary bases for further activities, such as special protection or intensified research. ...

    • An Investigation of Optimal Light Source Setups for Photometric Stereo Reconstruction of Historical Coins 

      Brenner, Simon; Zambanini, Sebastian; Sablatnig, Robert (The Eurographics Association, 2018)
      In this paper, we address the 3D reconstruction of historical coins by means of Photometric Stereo. We investigate the influence of the number and arrangement of lights to the reconstruction quality by comparing mean angular ...

    • Multi-Light Energy Map 

      Lardeux, Florian; Marchand, Sylvain; Gomez-Krämer, Petra (The Eurographics Association, 2018)
      We propose a model to represent quasi-flat objects, such as coins or amphora stamps. These objects are flat surfaces, meaning their length and their width largely exceed their height, and feature a distinctive relief. This ...

    • Multiple Material Layer Visualization for Cultural Heritage Artifacts 

      Moutafidou, Anastasia; Adamopoulos, Georgios; Drosou, Anastasios; Tzovaras, Dimitrios; Fudos, Ioannis (The Eurographics Association, 2018)
      Material aging has a significant effect on the appearance of cultural heritage objects. These aging effects depend on material composition, object usage and weathering conditions but also on physical and chemical substance ...

    • New Haven Building Archive: A Database for the Collection, Study, and Communication of Local Built Heritage 

      Rubin, Elihu; Akhtar, Saima; Brown, Benedict; Rushmeier, Holly (The Eurographics Association, 2018)
      The New Haven Building Archive (NHBA) is a digital, mobile, and interactive field guide to New Haven, Connecticut's built heritage. As an interactive digital guide and database for local buildings, the NHBA harnesses digital ...
