      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 ...

    • Objective and Subjective Evaluation of Virtual Relighting from Reflectance Transformation Imaging Data 

      Pintus, Ruggero; Dulecha, Tinsae; Jaspe, Alberto; Giachetti, Andrea; Ciortan, Irina; Gobbetti, Enrico (The Eurographics Association, 2018)
      Reflectance Transformation Imaging (RTI) is widely used to produce relightable models from multi-light image collections. These models are used for a variety of tasks in the Cultural Heritage field. In this work, we carry ...

    • On Combining Epigraphy, TLS, Photogrammetry, and Interactive Media for Heritage Documentation: The Case Study of Djehutihotep's Tomb in Dayr al-Barsha 

      Lima, Roberto de; Sykora, Toon; Meyer, Marleen De; Willems, Harco; Vergauwen, Maarten (The Eurographics Association, 2018)
      The governors' tombs located at Dayr al-Barsha are considered among the most important monuments of the Egyptian Middle Kingdom. Unfortunately, due to quarrying activities, looting, and natural catastrophes, the archaeological ...

    • Participatory Co-creation of a Public Sculpture Incorporating 3D Digital Technologies 

      Echavarria, Karina Rodriguez; Janzon, Karin; Wright, Jonathan (The Eurographics Association, 2018)
      This paper presents a interdisciplinary project between artists, civic groups, heritage organisations, technical experts and communities to co-create a piece of artwork for the community. Constellation is the name of the ...

    • Proxy Painting 

      Lange, Vanessa; Kurth, Philipp; Keinert, Benjamin; Boss, Martin; Stamminger, Marc; Bauer, Frank (The Eurographics Association, 2018)
      For archaeologists it is often desireable to present statues in their original coloration. With projection mapping real-world surfaces are augmented by digital content to create compelling alterations of the scene's visual ...

    • Shape Analysis Techniques for the Ayia Irini Case Study 

      Scalas, Andreas; Vassallo, Valentina; Mortara, Michela; Spagnuolo, Michela; Hermon, Sorin (The Eurographics Association, 2018)
      The typical approach for archaeological analysis is mainly qualitative and, as such, subjective. Even when some measures are reported in the documentation of artefacts, they are often approximate or ambiguous. Conversely, ...

    • A Social Platform to Support Citizens Reuse of Open 3D Visualisations: a Citizen Science Approach 

      Donato, Renato De; Santo, Massimo De; Negro, Alberto; Pirozzi, Donato; Rizzolo, Diletta; Santangelo, Gianluca; Scarano, Vittorio (The Eurographics Association, 2018)
      There is a growing interest in the world of Open Data, with many initiatives in the Cultural Heritage field. Platforms like Europeana, archive.org, Open Heritage by Google are only few examples of on-line catalogues full ...
