    Authoring Animated Interactive 3D Museum Exhibits using a Digital Repository
    (The Eurographics Association, 2012) Zmugg, René; Thaller, Wolfgang; Hecher, Martin; Schiffer, Thomas; Havemann, Sven; Fellner, Dieter W.; David Arnold and Jaime Kaminski and Franco Niccolucci and Andre Stork
    We present the prototype of a software system to streamline the serial production of simple interactive 3D animations for the display in museum exhibitions. We propose dividing the authoring process in two phases, a designer phase and a curator phase. The designer creates a set of configurable 3D scene templates that fit with the look of the physical exhibition while the curator inserts 3D models and configures the scene templates; the finished scenes are uploaded to 3D kiosks in the museum. Distinguishing features of our system are the tight integration with an asset repository and the simplified scene graph authoring. We demonstrate the usefulness with a few examples.

    Insourcing, Outsourcing and Crowdsourcing 3D Collection Formation: Perspectives for Cultural Heritage Sites
    (The Eurographics Association, 2012) Kaminski, Jaime; Echavarria, Karina Rodriguez; Arnold, David; Palma, Gianpaolo; Scopigno, Roberto; Proesmans, Marc; Stevenson, James; David Arnold and Jaime Kaminski and Franco Niccolucci and Andre Stork
    This paper presents three different propositions for cultural heritage organisations on how to digitise objects in 3D. It is based on the practical evaluation of three different deployment experiments that use different methods and business models for mass 3D-acquisition. These models are: developing the skills of in-house staff within an organisation, the use of external professionals and using crowdsourcing as a mechanism for developing the 3D collection. Furthermore, the paper provides an analysis of these models, lessons learned and practical recommendations for cultural heritage organisations. The analysis includes considerations of issues such as strategy, size of the organisation, skills, equipment, object accessibility and complexity as well as the cost, time and quality of the 3D technology. The paper concludes that most organisations are able to develop 3D collections but variations in the result will be reflected by the strategic approach they place on innovative 3D technologies.

    Petroglyph Classification using the Image Distortion Model
    (The Eurographics Association, 2012) Deufemia, Vincenzo; Paolino, Luca; Lumley, Henry de; David Arnold and Jaime Kaminski and Franco Niccolucci and Andre Stork
    Petroglyphs are prehistoric engravings in stone unrevealing stories of ancient life and describing a conception of the world transmitted till today. The great number of sites and the high variability in the artifacts makes their study a very complex task. Thus, the development of tools which automate the recognition of petroglyphs is essential not only for supporting archaeologist to understand petroglyph symbols and relationships, but also for the anthropologists who are interested in the evolution of human beings. However, many challenges exist in the recognition of petroglyph reliefs mainly due to their high level of distortion and variability. To address these challenges, in this paper we present an automatic image-based petroglyph recognizer that focuses on the visual appearance of the petroglyph in order to assess the similarity of petroglyph reliefs. The proposed matching algorithm is based on an image deformation model that is computationally efficient and robust to local distortions. The classification system has been applied to an image database containing 17 classes of petroglyph symbols from Mount Bego rock art site achieving a classification rate of 68 percent.
