3DHOG for Geometric Similarity Measurement and Retrieval for Digital Cultural Heritage Archives
(IEEE, 2015) Eckeren, Katharina van; Tausch, Reimar; Santos, Pedro; Fellner, Dieter W.; Gabriele Guidi and Roberto Scopigno and Juan Barceló
With projects such as CultLab3D, 3D Digital preservation of cultural heritage will become more affordable and with this, the number of 3D-models representing scanned artefacts will dramatically increase. However, once mass digitization is possible, the subsequent bottleneck to overcome is the annotation of cultural heritage artefacts with provenance data. Current annotation tools are mostly based on textual input, eventually being able to link an artefact to documents, pictures, videos and only some tools already support 3D models. Therefore, we envisage the need to aid curators by allowing for fast, web-based, semi-automatic, 3D-centered annotation of artefacts with metadata. In this paper we give an overview of various technologies we are currently developing to address this issue. On one hand we want to store 3D models with similarity descriptors which are applicable independently of different 3D model quality levels of the same artefact. The goal is to retrieve and suggest to the curator metadata of already annotated similar artefacts for a new artefact to be annotated, so he can eventually reuse and adapt it to the current case. In addition we describe our web-based, 3D-centered annotation tool with meta- and object repositories supporting various databases and ontologies such as CIDOC-CRM.
Palazzo Raimondi in Cremona - 3D Survey and Diagnostic Tests for the Knowledge of Construction Techniques and Historical Materials
(IEEE, 2015) Cardaci, Alessio; Versaci, Antonella; Roberti, Giulio Mirabella; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The paper deals with the 3D survey of Palazzo Raimondi in Cremona, featuring a renowned Renaissance façade, first step of a knowledge program aimed to define strengthening strategies consistent with the objective of building conservation. The laser-scanning campaign involved both external facades and the loggia on the court, extending to the flat coved vaults of the first floor, allowing detecting possible deviations from an ideal geometric reference. Non-destructive tests were also performed on materials and structures in order to widen the awareness on building behavior and attempt a first vulnerability analysis.
Mass Customization for Cultural Heritage 3D Models
(IEEE, 2015) Quantin, Matthieu; Hervy, Benjamin; Laroche, Florent; Kerouanton, Jean-Louis; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Digital technologies in the last twenty years have offered cultural heritage (CH) new possibilities in conservation and promotion. 3D digitization has especially become more and more affordable and efficient. This leads to massive digitization projects and increasing amount of CH digital data. As an engineering team working on industrial techniques for reverse engineering, we are deeply affected by this effect. In this paper we propose a way to combine semantic information on top of the acquisition and modeling steps in order to manage heterogeneous historical data. We illustrate our approach with a use case composed of three overlapping historical objects related to Nantes' harbour history.
Analyzing the Evolution of Deterioration Patterns - A First Step of an Image-based Approach for Comparing Multitemporal Data Sets
(IEEE, 2015) Peteler, Friederike; Gattet, Eloi; Bromblet, Philippe; Guillon, Odile; Vallet, Jean-Marc; Luca, Livio De; Gabriele Guidi and Roberto Scopigno and Juan Barceló
When documenting and analyzing cultural heritage, the monument states can be described by multitemporal data sets, which however present a complication for the elaboration and examination process. This difficulty leads to the necessity to improve the analyze process in order to expand the documentation process and help experts to enrich and share information about the historical buildings. Therefore an approach of change measurement, which supports the chronical comprehension of a building by visualizing and quantifying the dimensional temporal effects was elaborated, where the analyze process of a multitemporal data set was based on the interpretation of depth map images. These maps were obtained by generating ortho images of an object that was created on purpose by setting up an experimentation to acquire a multitemporal data set. This approach is the first step of a wider ongoing research about change detection processes on multitemporal data sets.
A 3D Kinematic Model for Assessing the Seismic Capacity of the Frigidarium of the Baths of Diocletian
(IEEE, 2015) Sadholz, Aaron; Muir, Christopher; Perucchio, Renato; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The Frigidarium of the Baths of Diocletian in Rome is one of the largest extant heritage structures built with unreinforced masonry material. The structural capacity of the Frigidarium to resist lateral accelerations generated by an earthquake is assessed by pushover analysis based on a limit kinematic approach. A 3D solid model of the Frigidarium modular section is subdivided into rigid blocks by cutting planes corresponding to the fracture surfaces determined by a preliminary nonlinear FE analysis. The blocks are then connected by rotational hinges to form a mechanism anchored to a base platform that translates horizontally with increasing acceleration. The mechanism, initially in static equilibrium, is eventually driven into dynamic conditions by the inertial forces generated by the moving platform. The intensity of the acceleration at the limit of the static condition (i.e., at the moment of impending motion) defines the structural capacity. A series of tests is conducted to evaluate the sensitivity of the model to changes in fracture orientation and hinge location, and to the introduction of friction between two blocks. Based on the current results, the capacity can be assessed at about 0.4g.
Archive To Repertoire - Motion Capture and Motion Sensing Data for Digital Intangible Heritage (DIH)
(IEEE, 2015) Khan, Muqeem; Gabriele Guidi and Roberto Scopigno and Juan Barceló
This study investigates the transformation of digital documentation of Kung Fu into an interactive performative space for public engagement. The study creates an interface for learning the repertoire of forms from significant lineages from the south Chinese traditions-contributing to the perpetuation of this art form. The investigation will contribute to the theoretical understandings of the relationships between archive and repertoire, specifically in relation to performance and intangible heritage. The intricate user interaction in this study enforces the visitor's perception that the Kung Fu instructor is present behind the screen, which simulates physical intimacy.
Surface Shape Studies of the Art of Paul Gauguin
(IEEE, 2015) Cossairt, Oliver; Tumblin, Jack; Huang, Xiang; Stratis, Harriet; Broadway, Mary; Bearman, Greg; Doehne, Eric; Walton, Marc; Matsuda, Nathan; Katsaggelos, Aggelos; Kronkright, Dale; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Starting in the 1890s the artist Paul Gauguin (1848- 1903) created a series of prints and transfer drawings using techniques that are not entirely understood. To better understand the artist's production methods, photometric stereo was used to assess the surface shape of a number of these graphic works that are now in the collection of the Art Institute of Chicago. Photometric stereo uses multiple images of Gauguin's graphic works captured from a fixed camera position, lit from multiple specific angles to create an interactive composite image that reveals textural characteristics. These active images reveal details of sequential media application upon experimental printing matrices that help resolve longstanding art historical questions about the evolution of Gauguin's printing techniques. Our study promotes the use of photometric stereo to capitalize on the increasing popularity of Reflectance Transformation Imaging (RTI) among conservators in the world's leading museums.
Studying Shape Semantics of an Architectural Moulding Collection - Classifying Style Based on Shape Analysis Methods
(IEEE, 2015) Echavarria, Karina Rodriguez; Song, Ran; Gabriele Guidi and Roberto Scopigno and Juan Barceló
As technologies for 3D acquisition become widely available, it is expected that 3D content will become increasingly popular. Nevertheless, to provide access and enable the creative use of 3D content, it is necessary to address challenges such as the availability of open repositories dedicated to 3D content and the automatic enrichment of 3D content with suitable metadata so that content does not get lost. To address these challenges, this paper presents research on developing technologies to support the organisation and discoverability of 3D content in the Cultural Heritage (CH) domain. The main contributions of the paper include an ontology for documenting 3D representations of architectural mouldings decorated with ornament. In addition, a shape analysis method to improve the information that is automatically extracted from a 3D shape is proposed. This method is tested on part of a collection of Regency ornament mouldings found in domestic interiors. This content provides a rich dataset on which to explore issues common to many CH artefacts, such as design styles, patterns and motifs.
AMICA - Virtual Reality as a Tool for Learning and Communicating the Craftsmanship of Engraving
(IEEE, 2015) Carrozzino, Marcello; Lorenzini, Cristian; Evangelista, Chiara; Tecchia, Franco; Bergamasco, Massimo; Gabriele Guidi and Roberto Scopigno and Juan Barceló
We hereby present the progress of the work ongoing on AMICA, a project aiming at disseminating to the public at large the activities related to the craft of engraving and printmaking by means of an Immersive Virtual Reality (VR) system. The final platform will constitute not only a means for communicating and promoting such activities, but also an interactive learning tool to be used in vocational courses.

Building Information Modelling for Historical Building Historic Jeddah - Saudi Arabia
(IEEE, 2015) Baik, Ahmad; Boehm, Jan; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The topic of how the municipality of Jeddah can document, produce and preserve complete engineering information and drawings for historical buildings is one of the most important issues facing the Historic Jeddah district in the Kingdom of Saudi Arabia. The concept of using a remote collection of survey data with Architectural Photogrammetry and Terrestrial Laser Scanning has been accepted in several heritage locations worldwide. Additionally, the combination of the resulting information and Building Information Modelling has been developed as a technique to manage and document these historical buildings. In the last 20 years, several traditional approaches have been used to document, record, and survey heritage buildings in Historic Jeddah; however, these techniques have sometimes delivered unreliable information, taken a long time and inevitably omitted key details. This paper will focus on using Jeddah Historical Building Information Modelling; to produce complete engineering information and drawings.
Interactive Segmentation of Rock-Art in High-Resolution 3D Reconstructions
(IEEE, 2015) Zeppelzauer, Matthias; Poier, Georg; Seidl, Markus; Reinbacher, Christian; Breiteneder, Christian; Bischof, Horst; Schulter, Samuel; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Petroglyphs (rock engravings) are important artifacts for the documentation and analysis of early human life. Recent improvements in 3D scanning and 3D reconstruction enable the accurate 3D reconstruction of petroglyphs from rock surfaces at sub-millimeter resolution. To enable the indexing, matching, and recognition of petroglyphs in petroglyph databases, the shapes must first be segmented from the reconstructed rock surface. The absence of robust 3D segmentation methods for petroglyphs leaves a gap in the digital processing workflow. In this paper, we present a semi-automatic method for petroglyph segmentation for high-resolution 3D surface reconstructions. A comprehensive evaluation shows that our method is able to robustly segment petroglyphs with high accuracy and that the incorporation of 3D information is crucial to solve the segmentation problem. The presented method represents a major step towards the completion of a full 3D digital processing workflow of petroglyphs.
Managing Digital Heritage - an Analysis of the Education and Training Curriculum for Africa's Archives and Records Professionals
(IEEE, 2015) Katuu, Shadrack; Ngoepe, Mpho; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The education and training of archives and records professionals in Africa can be traced back several decades. Archives and records practitioners in Africa's different countries have, over the years, taken varying paths to attain their professional qualifications. A number of publications have offered an analysis of the historical developments. This paper outlines progress on an ongoing study by InterPARES Trust Africa Team that examines the curricula in different Africaneducational institutions and investigates the extent to which they address the increasingly complex environment that includes the management of digital records in networked environments. It is hoped that the study will inform curriculum development and review in the area of digital records at the institutions of higher learning in Africa.
4D Investigation of Digital Heritage - An Interactive Application for the Auxiliary Fortress of Carnuntum
(IEEE, 2015) Juan, Torrejón Valdelomar; Matthias, Kucera; Wallner, Mario; Brandtner, Joachim; Sandici, Vlad; Neubauer, Wolfgang; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Innovative methods (e.g. geophysical prospection, remote sensing prospections, 3D modeling and visualization) adapted to Cultural Heritage and Archaeology open a wide field of research which needs appropriate techniques, skills and workflows. However, Virtual Archaeology (VA) must be understood not only as a passive instrument for visualizing the data and results but rather as a digital tool that provides an interactive four dimensional framework where the user is able to visualize, explore, analyze and evaluate both raw-data and 3D reconstructions. In this paper we would like to present a new developed interactive application called Arch4DInspector developed by the Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology (LBI ArchPro).
Exploiting Program Guides for Contextualisation
(IEEE, 2015) Baltussen, Lotte; Karavellas, Themistoklis; Ordelman, Roeland; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Archives of cultural heritage organisations typically consist of collections in various formats (e.g. photos, video, texts) that are inherently related. Often, such disconnected collections represent value in itself but effectuating links between 'core' and 'context' collection items in various levels of granularity could result in a 'one-plus-one-makes-three' scenario both from a contextualisation perspective (public presentations, research) and access perspective. A key issue is the identification of contextual objects that can be associated with objects in the core collections, or the other way around. Traditionally, such associations have been created manually. For most organizations however, this approach does not scale. In this paper, we describe a case in which a semi-automatic approach was employed to create contextual links between television broadcast schedules in program guides (context collection) and the programs in the archive (core collection) of a large audiovisual heritage organisation.
Ceramics and 3D Technology: A Medieval Assemblage from Nemea, Greece
(IEEE, 2015) Athanassopoulos, Effie; Shelton, Kim; Gabriele Guidi and Roberto Scopigno and Juan Barceló
This work in progress reports on the application of 3D laser scanning to the study of medieval pottery from the excavations of the Sanctuary of Zeus at Nemea, Greece. As 3D modeling methods continue to improve, they offer an attractive alternative for artifact documentation, analysis and sharing of data. Here we present some examples and suggest that the advantages of 3D technology over the traditional methods of documentation are significant.
VisProcH - Visual Reasoning Process for Heritage Valuation
(IEEE, 2015) Respaldiza, Arantza; Wachowicz, Monica; Gabriele Guidi and Roberto Scopigno and Juan Barceló
This article describes the methodology that results in a visual reasoning process for heritage valuation, which has been based on a descriptive modeling process and have characterized three levels: meta-, analysis and operational. The proposed approach is not only about heritage but the complex relationship between people and heritage. The agents are the protagonists in the process, along with heritage; they give value to the testimonies of past life and imbue them with meaning. The hypothesis of this research argues that a visual reasoning process for heritage valuation allows people involved in the process to initiate an interaction with a heritage and to build its mental image to reach certain conclusions regarding its value and meaning. Therefore, this approach of a visual reasoning process is used to detect changes in value of heritage and its polyhedral dimension in spatial and temporal terms. The proposed process enables potential agents to be actively involved in their own heritage valuation.
BIM: An Integrated Model for Planned and Preventive Maintenance of Architectural Heritage
(IEEE, 2015) Fregonese, Luigi; Achille, Cristiana; Adami, Andrea; Fassi, Francesco; Spezzoni, Anna; Taffurelli, Laura; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Modern digital technologies give us great possibilities to organize knowledge about constructions, regarding multidisciplinary fields like preservation, conservation and valorization of our architectural heritage, in order to suggest restoration projects and related work, or to suppose a planned preventive maintenance. New procedures to archive, analyze and manage architectural information find a natural support in 3D model, thanks to the development of capacities of new modeling software. Moreover, if the model contains or interfaces with a heterogeneous archive of information, as it is for BIM, this model can be considered as the bases of critical studies, projects of restoration, heritage maintenance, integrated management, protection, and valorization, and evaluation of economic aspects, management and planning, that can flow into a planned preventive maintenance [1]. The aspect that limit the use of BIM technology is the set up parametric object library inside programs: the standardized level of these objects deals difficulty with survey and restoration issues, where each single element has its own historical and architectural characterization [2]. From this foreword, the goal of this research is more evident: the possibilities of using BIM modeling to the existing constructions and cultural heritage, as a support for the construction and management of a Plan for planned preventive maintenance.
