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.
3D Visualisation of Archaeological Structures from Geophysical Explorations in Alarcos site Sector III (Ciudad Real)
(IEEE, 2015) Sánchez, José Luis; Sánchez, Jesús; Merlo, Óscar; Gabriele Guidi and Roberto Scopigno and Juan Barceló
In this work, the results of the application of geophysics to the Alarcos' Sector III - one of the most important archaeological sites in La Mancha - are presented. The geophysical exploration was carried out with a two-fold objective: to obtain a stratigraphic characterisation of the Sector III subsoil, and to test the efficiency and limitations of the geophysical methods applied. These methods are Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT). Our research confirmed the potential existence of buried structures in the subsoil, which shows the potential of the combined used of geophysical techniques in the search for archaeological structures in site's subsoil in a non-destructive manner. The results are shown in different 3D images which allow the characteristics and spatial distribution of the buried structures to be determined, optimising therefore the planning of future archaeological actions.
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.
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).
A.I.M. - Advanced Interactive Map
(IEEE, 2015) Maiellaro, Nicola; Gabriele Guidi and Roberto Scopigno and Juan Barceló
This paper discusses the ongoing development of a tool to produce - through an authoring system - an interactive map with advanced functions. A first map has been produced in collaboration with the Municipality of Cetinje (Montenegro); a map of the Municipality of Gioia del Colle is still under construction with students of a secondary school. These activities concern the Mu.S.A. (Must See Advisor) Project, a cultural heritage booster aiming at giving visibility to less known sites - as potential tourism destinations - by valuing knowledge from selected communities.
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.
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.
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.
Assistive Visual Framing in 3D Dense Points Cloud
(IEEE, 2015) Habibi, Zaynab; Caron, Guillaume; Mouaddib, El Mustapha; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Recent progress in digital technology and its popularity in the context of cultural heritage are contributing to the emergence of several applications using a very large and dense digitization of archaeological sites or historical monuments. Navigation in such virtual environment is difficult especially for novice users. In this paper, we propose a new approach in order to make easier the navigation process by performing an assistive visual framing. This approach exploits a new visual feature: the image saliency-based Gaussian mixture. We applied our method on many different environments and we present the example of the Saint S´ebastien chapel of the cathedral Notre Dame of Amiens. In order to evaluate our method, we present user evaluation and comparison between manual, assistive and automatic framing.
Automated Color Clustering for Medieval Manuscript Analysis
(IEEE, 2015) Yang, Ying; Pintus, Ruggero; Gobbetti, Enrico; Rushmeier, Holly; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Given a color image of a medieval manuscript page, we propose a simple, yet efficient algorithm for automatically estimating the number of its color-based pixel groups, K. We formulate this estimation as a minimization problem, where the objective function assesses the quality of a candidate clustering. Rather than using all the features of the given image, we carefully select a subset of features to perform clustering. The proposed algorithm was extensively evaluated on a dataset of 2198 images (1099 original images and their 1099 variants produced by modifying both spatial and spectral resolutions of the originals) from the Yale's Institute for the Preservation of Cultural Heritage (IPCH). The experimental results show that it is able to yield satisfactory estimates of K for these test images.
An Automatic Word-spotting Framework for Medieval Manuscripts
(IEEE, 2015) Pintus, Ruggero; Yang, Ying; Gobbetti, Enrico; Rushmeier, Holly; Gabriele Guidi and Roberto Scopigno and Juan Barceló
We present a completely automatic and scalable framework to perform query-by-example word-spotting on medieval manuscripts. Our system does not require any human intervention to produce a large amount of annotated training data, and it provides Computer Vision researchers and Cultural Heritage practitioners with a compact and efficient system for document analysis. We have executed the pipeline both in a single-manuscript and a cross-manuscript setup, and we have tested it on a heterogeneous set of medieval manuscripts, that includes a variety of writing styles, languages, image resolutions, levels of conservation, noise and amount of illumination and ornamentation. We also present a precision/recall based analysis to quantitatively assess the quality of the proposed algorithm.
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.
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.
Carousel Rides - New Tools for Navigation in Intangible Cultural Heritage
(IEEE, 2015) Artese, Maria Teresa; Gagliardi, Isabella; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The creation of new tools to navigate the intangible cultural heritage data goes through the analysis of available data and their integration with new information that can be obtained either automatically, developing specific algorithms, either manually by intervention of sector experts. This new information, combined with those already available, permit the construction of recreational paths and discovery games that enable even a less experienced audience coming in contact with the intangible heritage. In this paper we present a work in progress to show new tools to navigate the intangible in different ways.
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.
Create Your Menu - Discovering Traditional Recipes
(IEEE, 2015) Gagliardi, Isabella; Artese, Maria Teresa; Gabriele Guidi and Roberto Scopigno and Juan Barceló
Expo2015 has focused attention on the culinary memories, healthy food and traditional methods, handed down over the years, to cultivate and use what nature has to offer, in a sustainable way. In this paper we present the application Create your menu (the work is still in progress) able to query the ECHI-ICH database, an inventory of Intangible Cultural Heritage, to find recipes/foods and compose the results in an healthy menu. The application is able to retrieve, within the cards of the ECHI-ICH inventory, those that are related to foods, then identify the main ingredients and extract the nutrients, using open data about food, to compose traditional and healthy meals.

Documentation and 3D Modeling of Railway Industrial Heritage - Study of the Cajo-Santander Locomotive Shed
(IEEE, 2015) Cobos, Oscar Jesús Cosido; Soto, José Luís Lalana; Terán, Leticia; Campi, Massimiliano; Catuogno, Raffaele; Ramírez, Lucia Hernández; Llamas, José Pereda; Vidal, Esteban Sainz; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The works of three-dimensional documentation of the industrial heritage of Santander, which are carried out under the initiative of the authors of the article had the cooperation of the University of Cantabria, University of Naples ''Federico II'', University of Valladolid and the 3DIntelligence company. Within this project, it has been made the documentation of locomotive shed and the roundabout structure, key piece of industrial railway heritage in Santander. For this project we used the fusion of data (point clouds) from the Scanner-Laser and data from convergent photogrammetry. This initiative has enjoyed the cooperation of the RENFE company, who allowed access to their infrastructure. Both structures are currently in use, making complex the data collection phase.
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.
Exploration of the Changing Structure of Cities: Challenges for Temporal City Models
(IEEE, 2015) Périnaud, Clémentine; Gesquière, Gilles; Gay, Georges; Gabriele Guidi and Roberto Scopigno and Juan Barceló
The ALARIC project (Incremental Urban Change Research Project) is dedicated to the production of geo-historical information concerning two formerly industrial cities of the Lyon-Saint-Etienne region (19th and 20th century). The explo-ration of the incremental nature of urban change implies identifying when certain historical processes took place, such as the shift from one-off to systematic construction and changes in urban planning strategies. Specifically, the case stu-dy investigates the emergence of local urban projects to compare the transformation processes of the urban fabric and to specify the pace of urban change. Historical records will be accessed through a virtual mapping environment based on the temporal reconstitution of cities in two dimensions, and sometimes for special cases in three dimensions. This paper presents methodological principles to reconstruct former cities in order to inquire urban change and requirements for effective sharing of hypotheses on the various states of the past urban landscape and associated transformation processes.
