An Android Application for Computing Selected Areas on Images in Restauration of Mosaics and Frescos

Author(s): Miloš Stošić,Radomir S. Stanković / Language(s): Issue: V/2015

This paper describes an Android application which allows computation of the physical area of a selected region of an image. The System is intended for helping archaeologists on fields and archaeological sites. The basic principle of the operations is that the user of the application takes a picture of some shape, object or landscape. First, the user has to select the unit of measurement that is always present on the screen, by using already implemented tools. Then you select an appropriate mosaic that you want to be calculated, and the calculated area is presented on the screen. The major advantage of the system is to resolve the problem of computating the area of the damaged part of the mosaics on field.

Technology-enhanced Learning for Cultural Heritage

Author(s): Lilia Pavlova,Lubomil Draganov,Detelin Luchev,Desislava Paneva-Marinova,György Szántó,Zsolt László Márkus,Tibor Szkaliczki / Language(s): Issue: V/2015

This paper demonstrates an approach for technology-enhanced learning, combining analysis, collaborative work, mobile learning (m-learning for short), discussion, and learning-by-authoring approaches in order to achieve more active participation of the learners during the reception of knowledge and to stimulate their creative thinking. The learners visit famous churches, monasteries, museums, etc., where they can see samples of Bulgarian Iconography supported by m-learning. They rely on the GUIDE@HAND platform containing personalized collections presenting location, historical data, pictures, etc. Multimedia and other information resources are delivered through the Virtual Encyclopaedia of the East-Christian Art digital library (BIDL)—a web-based environment for registration, documentation, access and exploration of Bulgarian iconographical artefacts. The main goal of the learners is to create their own learning material/project by analysing the available resources. The presented use case also involves collaborative work and discussion approaches in order to attract learners and support their more active participation in the learning process.

Implementation of 3D Sound Effects for Museums Using Raspberry Pi and Home Theatre System

Author(s): Miloš Radmanović / Language(s): Issue: V/2015

In recent years, museums are exploring digital and computer technologies to enhance visitor experience and for that purpose a variety of systems for creating 3D sound effects for museums have been implemented. The growth of the performance of low-cost minicomputers leads to the issue of their integration with home theatre systems for simple implementation of 3D sound effects. This paper presents one solution for implementing 3D sound effects for auditory illusions immersive experiences in museums using the Raspberry Pi minicomputer and a home theatre system with 5.1 surround sound. With this so-lution it is possible to create a museum visitor detector via Raspberry Pi that uses motion detection to trigger 3D sound playing on a home theatre system. The solution was experimentally tested developing an audio system called “Auditory Illusions for Concentration Camp Museums”. The system was developed to enrich the exhibition in the Red Cross Second World War Concentration Camp Museum in the city of Niš, Serbia.

DCH-RP and PREFORMA: Two Case Studies on the Digital Preservation of Cultural Heritage

Author(s): Antonella Fresa,Claudio Prandoni / Language(s): Issue: V/2015

The huge amount of digital cultural heritage data is growing every day thanks to the digitisation programmes carried out by cultural institutions. These data should continue to be available in the future to anyone who wishes or needs to access them. This is a very important challenge memory institutions have to face nowadays, and several questions need to be answered to this regard: How will we ensure the long-term preservation and access to our digital information? Who should select which digital data should be saved? How will we successfully store and migrate data as technology evolves? Understanding of digital preservation requires consideration of two main aspects: organisation and technology. Several projects have been funded in the last years to work on these topics by the European Commission. This paper presents the work that is being carried out in two of these projects: DCH-RP and PREFORMA.

Visual Lifelogging in the Era of Outstanding Digitization

Author(s): Mariella Dimiccoli,Petia Radeva / Language(s): Issue: V/2015

In this paper, we give an overview on the emerging trend of the digitized self, focusing on visual lifelogging through wearable cameras. This is about continuously recording our life from a first-person view by wearing a camera that passively captures images. On one hand, visual lifelogging has opened the door to a large number of applications, including health. On the other, it has also boosted new challenges in the field of data analysis as well as new ethical concerns. While currently increasing efforts are being devoted to exploit lifelogging data for the improvement of personal well-being, we believe there are still many interesting applications to explore, ranging from tourism to the digitization of human behavior.

Mapping the Conservations Status of Easel Painting. Craquelure Structure Visualization by Binary Image Segmentation Approach

Author(s): Magdelena Stoyanova,Tibor Lukić / Language(s): Issue: V/2015

In easel painting (icons) mapping the status of conservation (MCS) is a complex process of prospecting in various spectral, graphic, and spatial techniques, integral analysis and “technical” visualizations of the data whose function is to lay out detected damages or symptoms, not directly perceivable from the VIS, UV, IR or X-r imaging. In this work, the results of a multi-methodological survey applied to the end of detecting sharp discontinuities (boundary of cavities, wrinkles and fractures in the host medium) are illustrated. As, due to the microscopic size and depth of a crackle/wrinkle fragment or net, it may be rather difficult to single out its position and extent because of the generally low signal-to-noise (S/N) ratio, binary image segmentation and high-resolution data acquisition has been adopted for improving the visibility of the studied area.
