    Dense Image Matching: comparisons and analyses
    (The Eurographics Association, 2013) Remondino, Fabio; Nocerino, Erica; Menna, Fabio; Nex, Francesco; Spera, Maria Grazia; Gonizzi-Barsanti, Sara; -
    The paper presents a critical review and analysis of dense image matching algorithms. The analyzed algorithms stay in the commercial as well open-source domains. The employed datasets include scenes pictured in terrestrial and aerial blocks, acquired with convergent and parallel-axis images and different scales. Geometric analyses are reported, comparing the dense point clouds with ground truth data.

    Design and implement a reality-based 3D digitisation and modelling project
    (The Eurographics Association, 2013) Remondino, Fabio; Menna, Fabio; Koutsoudis, Anestis; Chamzas, Christos; El-Hakim, Sabry; -
    3D digitisation denotes the process of describing parts of our physical world through finite measurements and representations that can be processed and visualised with a compute r system. Reality-based 3D digiti sation is essential for the documentation, conservation and preservation of our Cultural Heritage. This article composes a critical review of the digitisation pipeline, ranging from sensor selection and planning to data acquisition, processing and visualisation.

    Feature-based automatic 3D registration for cultural heritage applications
    (The Eurographics Association, 2013) Tombari, Federico; Remondino, Fabio; -
    This paper presents a review of the state-of-the-art techniques in the field of 3D invariant features for the automatic registration of point clouds and 3D meshes. The paper proposes also a multi-stage 3D registration pipeline implemented using the PCL libraries. Experiments are carried out on datasets related to heritage scenarios and addressing large-scale outdoor data acquisitions as well as small objects.

    Quick textured mesh generation for massive 3D digitization of museum artifacts
    (The Eurographics Association, 2013) Gonizzi, Sara; Micoli, Laura L.; Guidi, Gabriele; -
    The goal of the "3D Icons" European Project, is to provide Europeana with accurate 3D models of Cultural Heritage artifacts. The purpose of this paper is to describe the specific optimized processing pipeline that has been set-up for digitizing a significant part of the Civic Archaeological Museum in Milan (Italy). Many technical and logistic issues for capturing 3D models in a Museum environment are addressed. In such framework the main problem is generating a good result by the technical point of view, minimizing the impact on the usual Museum activity during 3D capture operations, while shortening the processing time to the minimal allowed by the different applicable techniques. This condition led to precise choices related to the 3D acquisition techniques to be used (SfM), and the related data processing. This paper illustrates the aforementioned systematic aspects through three practical examples, showing good practices for image capturing and some 3D processing optimizations that allowed to speed the 3D models production at a level compliant to the final goal of more than 500 models in 36 months.

    A War Torn Memory Palace: Animating narratives of remembrance
    (The Eurographics Association, 2013) Kenderdine, Sarah; Mckenzie, Heidi; -
    ECLOUD WWI (2012) is a custom designed 9-metre by 3.5-metre interactive 3D projection environment and application developed by the Applied Laboratory for Interactive Visualization and Embodiment (ALIVE), City University of Hong Kong in partnership with Europeana's 1914 1918 project. The installation activates over 40,000 images of war memorabilia ascribed to 2,500 individual stories collected (crowdsourced) between 2009 2013, in an ongoing project undertaken across Europe. The installation instantaneously aggregates the digital imagery and its associative metadata within a unique immersive viewing experience. The visualization strategies engaged in ECLOUD WWI signal opportunities for new curatorial practices and embodied museography, re-deploying Internet data in situated museum settings. This paper begins by describing Europeana's data sourcing and collection methods as well as exploring the compelling nature of the memorabilia. ECLOUD WWI applies an integrative pluralist approach to the juxtaposition of image and memory. The discussion then explores participatory framework of the installation, demonstrating the shift from single-source authorship of a linear heritage to shared authorship between user, algorithm and data developed through strategies of recombinatory navigation and interactive narrative. The parallel presentation of historic objects in combination with subjective collected stories presents us the opportunity to redefine the creation of cultural memories. This inter-generational project also offers occasions for generative legacy-building in younger generations as the 2014 centenary of WWI is commemorated in the coming year.
