Interactive Digital 3D Puzzles of Archaeological Artefacts to Support Engagement Beyond the Museum Environment
Full text linkThe need for online 3D interactive experiences was evidenced during the COVID-19 lockdowns, as audiences across the world have been unable to visit museums, physically interact with their collections on site or digitally interact with technologies and digital media situated within such settings. As a response, this research addresses gaps identified in a review of the digital offerings from UK and US museums during the 2020 lockdowns, highlighting the limited number and nature of 3D interactive offerings provided, despite the wide efforts on 3D digitisation over the last decade. Thus, the research investigates the development and testing of an online 3D interactive activity, resembling a physical activity situated in the archaeological gallery of Brighton Museum and Art Gallery (UK). Through a pilot user survey, the research aims to understand what is the impact of such online offerings to better contextualise heritage collections; enhance cultural heritage learning and appreciation; and complement physical activities of similar nature. The analysis of audiences’' opinions about these interactions can be of great importance, as such activities have the power to enable active access to cultural heritage resources regardless of the physical location of users and transform heritage experiences in the long term. Our research indicates that, while the physical experience might offer advantages as far as it concerns the familiarity with the tactile nature of interaction, the digital counterpart has potential to allow for the experience of assembling the puzzle to achieve a wider reach
Virtual Dance Museum: the Case of Greek/Cypriot Folk Dancing
No full textIn this paper, we have designed and developed a virtual dance museum to provide the technological tools that allow for widely educating the public, most specifically the youngest generations, about the story, costumes, music, and history of our dances. The holistic documentation of our intangible cultural heritage creations is a critical necessity for the preservation and the continuity of our identity as Europeans. In that direction, we have employed a specially designed relational database schema that holistically structures the information within the database, and is ideal for archiving, presenting, further analyzing, and re-using dance motion data. Data have been retargeted to a virtual character, dressed with traditional uniform and simulated to achieve realism. The users can view and interact with the archived data using advanced 3D character visualization in three ways: via an online 3D virtual environment; in virtual reality using headset; and in augmented reality, where the 3D characters can co-inhabit the real world. Our museum is publicly accessible, and also enables motion data reusability, facilitating dance learning applications through gamification.Eurographics Workshop on Graphics and Cultural HeritageVirtual Museum
Reimagining a 2D Painted Portrait as a Kinetic 3D Sculpture
No full textThis paper describes a Cultural Heritage related project concerned with developing computer technology for reimagining a 2D painted still portrait made in a distinctive fine art style as an animated 3D sculpture whilst preserving the principal features of the initial painting yet resulting in an artefact of original quality. This work explores both artistic and technological aspects of a production pipeline. The case-study to prove the concept relies on Francis Bacon's ''Study for Portrait (Michel Leiris)''. A supplementary video shows the resulting animated piece with Bacon's voice-over.Eurographics Workshop on Graphics and Cultural HeritageShort Papers
Automatic Segmentation of Archaeological Fragments with Relief Patterns using Convolutional Neural Networks
No full textThe recent commodification of high-quality 3D scanners is leading to the possibility of capturing models of archaeological finds and automatically recognizing their surface reliefs. We present our advancements in this field using Convolutional Neural Networks (CNNs) to segment and classify the region around a vertex in a robust way. The network is trained with high-resolution views of the 3D models captured at different angles. The views represent both the model with its original textures and a colorization of the patches according to the value of the Shape Index (SI) in their vertices. The SI encodes local surface variations and we exploit the colorization of the model driven by the SI to generate other view and enrich the dataset. Our method has been validated on a relief recognition benchmark on archaeological fragments proposed within the SHape REtrieval Contest (SHREC) 2018.Eurographics Workshop on Graphics and Cultural HeritageReconstructio
Riedones3D: a Celtic Coin Dataset for Registration and Fine-grained Clustering
No full textClustering coins with respect to their die is an important component of numismatic research and crucial for understanding the economic history of tribes (especially when literary production does not exist, in celtic culture). It is a very hard task that requires a lot of times and expertise. To cluster thousands of coins, automatic methods are becoming necessary. Nevertheless, public datasets for coin die clustering evaluation are too rare, though they are very important for the development of new methods. Therefore, we propose a new 3D dataset of 2 070 scans of coins. With this dataset, we propose two benchmarks, one for point cloud registration, essential for coin die recognition, and a benchmark of coin die clustering. We show how we automatically cluster coins to help experts, and perform a preliminary evaluation for these two tasks. The code of the baseline and the dataset will be publicly available at https://www.npm3d.fr/coins-riedones3d and https: //www.chronocarto.eu/spip.php?article84&lang=fr.Eurographics Workshop on Graphics and Cultural HeritageReconstructio
Fully Automatic Mechanical Scan Range Extension and Signal to Noise Optimization of a Lens-Shifted Structured Light System
No full textDigitization of cultural heritage is of growing importance, both for its preservation for coming generations in the face of looming dangers of natural decay or intentional destruction, and current generations, that increasingly have access to virtual cultural heritage for interactive exploring or scientific analysis. These goals can only be achieved by 3D replicas at reasonable quality and resolution, to come as close as possible to the original. This brings about several challenges to overcome. The challenge of digitizing huge numbers of artefacts is addressed by CultLab3D, the first fully automatic 3D digitization system. Another challenge is the size of objects, as each digitization system is designed for a certain optimum measurement range, leaving which results in loss of quality. Due to optical and mechanical constraints, most systems are not able to faithfully reconstruct objects under a certain size limit in their full geometric detail. Historic coins are one good example, where the deterioration of the surface structure in most cases has progressed to a degree that it not even is perceptible through the fingernail. This challenge is addressed by a modular extension of CultLab3D, the MesoScanner, which is a structured light system that breaks limits in depth resolution through a mechanical lens-shifting extension, allowing physically shifting of fringe patterns on top of the well-known multi-period phase shift method. This is where this work adds two major improvements: First, the signal to noise ratio and thus reconstruction quality has been improved significantly through several algorithmic processing steps. Second, the physical limitation of the measurement range was removed using a 2D actuator steering the object mount, thus allowing for a measurement range at theoretically arbitrary size. This opens up the fully automatic handling of two scenarios: Complete digitization of objects exceeding the measurement range, and unsupervised digitization of large collections of small objects in one run.Eurographics Workshop on Graphics and Cultural HeritageShort Papers
Immersive Geometry-based and Image-based Exploration of Cultural Heritage Models
No full textRecent advances in 3D acquisition technologies have facilitated the inexpensive digitization of cultural heritage. In addition to the 3D digital model, in many cases multiple photo collections are also available. These photo collections often provide valuable information not included in the 3D digital model. In this paper we describe a VR-ready web application to simultaneously explore a cultural heritage model together with arbitrary photo collections. At any time, users can define a region of interest either explicitly or implicitly, and the application retrieves, scores, groups and shows a matching subset of the photos. Users can then select a photo to project it onto the 3D model, to inspect the photo separately, or to teleport to the position the photo was taken from. Unlike previous approaches for joint 2D-3D model exploration, our interface has been specifically adapted to VR. We conducted a user study and found that the application greatly facilitates navigation and provides a fast, intuitive access to the available photos. The application supports any modern browser running on desktop, mobile and VR headset systems.Eurographics Workshop on Graphics and Cultural HeritageEngaging with Cultural Heritag
Capture, Processing and Presentation of Digital Cultural Items: Feedback from Cultural Heritage Practitioners
No full textThe trend of digitizing analogue artefacts from cultural heritage collections to create cultural digital items remains ongoing. The user experience of Cultural Heritage Practitioners (CHP) should be understood in order to support academic efforts in producing practical contributions that benefit those working with cultural digital items. In this publication we follow a series of semi-structured interviews with 10 CHPs and supporting technical professionals who work with cultural digital items on a daily basis. We then code their responses for theme, analysing their thoughts and concerns regarding key topics connected to cultural digital items such as interactivity and the challenges of digitization within the culture heritage sector.Eurographics Workshop on Graphics and Cultural HeritageEngaging with Cultural Heritag
