The Norwegian University of Science and Technology (NTNU) is Norway’s second largest university in number of students. Today the full range university NTNU encompasses 7 faculties and 53 departments, with approximately 19000 students. Half of these are studying technology or natural sciences. NTNU has a staff of about 5000, with over 3000 in academic and scientific positions. Between 250 and 300 PhD-degrees are awarded yearly, within the fields of technology, science, arts and humanities, social sciences and medicine. NTNU has a broad range of contacts with International R&D actors, in academia as well as in industry. The annual budget of NTNU is around € 600 million, 25% of which is externally funded. NTNU is an active participant in the EU R&D Framework Programmes and participates in 75 FP7 projects. The Department of Computer and Information Science (IDI) is part of the Faculty of Information Technology, Mathematics and Electrical Engineering at NTNU. It has about 200 employees, including over 50 faculty members and about 90 PhD students.

Within PRESIOUS, the NTNU team brings expertise in Visual Computing, Erosion Chemistry, Project Management and Cultural Heritage data. Specifically, members of the Department of Computer and Information Science have been working, among others, on 3D Shape Analysis with applications in biometrics and 3D object retrieval; this expertise will be useful in modelling the geometrical side of the erosion process and in building the overall erosion model. Chemistry Department members will complement the erosion investigation from the chemical aspect, as they are studying the erosion of Cultural Heritage monuments from the chemical point of view. The project support team of NTNU has a long standing experience in running large projects successfully. Finally NTNU has a close link to Nidaros Cathedral Restauration Workshop, who will be providing us with useful 3D data.



The Athens University of Economics and Business Research Centre (AUEB-RC) was established in 1983 as part of the Athens University of Economics and Business in order to coordinate and facilitate research by the University's faculty members. The AUEB Computer Graphics Group (, a part of the Multimedia and Mobile Laboratory, conducts research on real-time rendering algorithms, 3D matching algorithms and 3D data processing. Previous work of the group includes pioneering contributions to the field of computational methods for archaeology, especially on 3D matching and reassembly algorithms. In the recent years, the group is very active in the domain of real-time rendering algorithms and systems. 

Due to the above fields of expertise, AUEB-RC is involved in the PRESIOUS project mainly in fragment matching and reassembly algorithms, the graphics engine design and implementation, as well as the integration activities. AUEB-RC seeks to drastically reshape core research on fundamental techniques for object reassembly, by merging previous knowledge on object matching algorithms with ongoing research on real-time GPU techniques and the contribution of the object-retrieval expertise of the other participants.



 The ATHENA Research and Innovation Centre (RIC) in Information, Communication and Knowledge Technologies was founded in 2003 comprising of three institutes and three technological units. It operates under the auspices of the Ministry of Education and Religious Affairs, Culture and Sports. It is based in Athens, with its Institutes located in Athens, Patras and Xanthi. ATHENA aims towards promotion of innovative information, communication and knowledge technologies in the industrial and services sectors, development of scientific and technological research in the sectors of information technology, knowledge, communication and automating production processes and the implementation as well as exploitation of results aiming at the production of laboratory prototypes, products and services. In relation to PRESIOUS, it maintains a state-of-the art digitisation centre, an archaeometry laboratory and several collaborating departments (cultural heritage, multimedia and computational systems), making it a multi-disciplinary research organisation that offers its services on applied innovative technologies in the domains of cultural heritage and education.

In PRESIOUS, ATHENA-RIC is mainly involved in the predictive digitization task for which novel 3D shape descriptors and efficient schemes for partial matching tasks will be developed. 


 Universität Konstanz

The Visual Analytics group was established with the Department for Computer and Information Science at University of Konstanz (UKON) in 2011 and since then is led by Tobias Schreck. We are working in the areas of 3D Object Retrieval, Digital Libraries, and Visual Analytics. The group focuses on innovative, effective user-oriented techniques for visual information retrieval and analysis in large data sets, including 3D object data, time-oriented research data, and text-oriented social media data. Tobias Schreck, since his PhD research, is working in the area of 3D object retrieval and the group collaborates actively in this domain, including co-organizing editions of the EG Workshop for 3D Object Retrieval (3DOR). 

In PRESIOUS, UKON is focused on innovative methods for object repair. Specifically, we will consider novel similarity-based approaches for reassembly and completion of partially represented objects from the 3D Cultural Heritage domain. To this end, appropriate partial retrieval methods need to be developed, which can retrieve the most appropriate models from a template shape repository for repair and completion purposes.

AICON 3D Systems GmbH is one of the world’s leading providers of optical camera-based 3D measuring systems. The company, founded in 1990, develops and distributes systems for the business areas of inspection and testing including car safety and tube inspection. Since the acquisition of Breuckmann GmbH in August 2012, the product range also includes scanners for 3D measurement of complex geometries.

The digital acquisition and documentation of cultural masterpieces is increasingly gaining importance — be it in architecture, fine arts, archaeology or paleontology. The contact-free 3D scanning technology of breuckmann Scanners works in the museum as well as at the archaeological site. It allows handling delicate objects with the utmost care and provides detailed 3D data with high-resolution color textures for thorough studies without using the original. AICON 3D Systems brings in PRESIOUS its invaluable know-how in 3D scanning technology, its business perspective in the CH and industrial applications and more than 20 years of expertise in large scanning projects.
