The Past

Many Cultural Heritage (CH) monuments are destroyed in the past and they are often lost forever. If there is no contemporary metric documentation of the historic objects available, the monument and the information about this monument could be disappeared and forgotten forever. The Siegesburg (also known as Segeberg castle) located on the "Kalkberg" (Chalk Mountain) in Bad Segeberg in Northern Germany, is a typical example for such a monument, which was destroyed by Swedish troops at the end of the Thirty Years' War in 1644. This important monument was only documented by a few historic isometric maps, but the castle and even the later castle ruin were totally destructed and demolished over the last centuries and disappeared forever. Furthermore, this significant memorial is even forgotten in many people's mind. <br><br> This contribution describes the physical and virtual return of the Siegesburg by 3D reconstruction using historic sources. The laboratory for Photogrammetry &amp; Laser Scanning of the HafenCity University Hamburg conducted this project in co-operation with the museum Alt-Segeberger Bürgerhaus (Old-Segeberg town house). The process of the 3D reconstruction and visualisation of both the Kalkberg and the castle is presented in this paper.

During the past years there has been the birth of significant projects about digitization and virtual preservation of cultural heritage. Such panorama offers great chance to develop 3D modeling for cultural heritage. 3D reconstruction offers a chance to digitize historic objects which are still extant, and also to reconstruct and visualize objects which are no longer extant and that can only be known from historic descriptions or depictions. The chapter focus on the latter aspect. In fact, 3D modeling of extant objects is technologically or logistically challenging but virtual reconstruction of non- or no longer- existent items adds more importance to interpretation of historic sources. This chapter illustrates the current situation taking into account the state of the art, the different suggestions in solving such kind of problem, and through up to date examples will suggest a possible unified method to give life to both lost buildings and never built ones. The goal is to find common points with other similar cases, to obtain a common procedure an to suggest ways of development.

The research of historical heritage is related to creation, storage and distribution of visual information about them. With the development of digital technologies, the three-dimensional scanning and visual regeneration of buildings of cultural heritage combined with 3D virtual reconstruction is becoming increasingly important tool for understanding and reconstructing the past. Instead of expensive laser scanning, cheaper photogrammetric methods for creating and processing of spatial (3D) images of historical and architectural monuments are finding a growing application. The article analyses the opportunities for use of different ICT tools, including inexpensive digital imaging options for preservation and exhibiting of large and diverse Bulgarian cultural heritage.

The article deals with the problem of collecting, preserving and researching the disappeared names of localities in the subjects of the Russian Federation, which for centuries have become an integral part of the historical and cultural heritage of the peoples of our country. The author believes that only a comprehensive analysis of the past oikonyms in nominational, lexical-semantic, historical-cultural, historical-ethnographic, local history aspects will restore the linguistic and cultural systems of different time periods in different microareals of the Russian Federation. The author comes to the conclusion that in order to preserve the historical memory of the disappeared names of geographical objects, local researchers need the support of regional state authorities and local self-government.

Ideological Manipulation

AbstractCultural heritage can offer tangible and intangible traces of the past. A past that shapes cultural identity, but also a past from which one sometimes wishes to detach oneself and which nevertheless needs to be remembered, even commemorated. These themes of memory, history and oblivion are examined by the philosopher Paul Ricoeur in his work La mémoire, l’histoire, l’oubli (2000). Inspired by these ideas, this paper analyses how they are closely linked to cultural heritage. Heritage serves as a support for memory, even if it can be mishandled, which in turn can affect heritage policies. Memory and heritage can be abused as a result of wounds from the past or for reasons of ideological manipulation or because of a political will to force people to remember. Furthermore, heritage, as a vehicule of memory, contributes to historical knowledge, but can remain marked by a certain form of subjectivism during the heritage and conservation operation, for which heritage professionals (representatives of the public authority or other experts) are responsible. Yet, the responsibility for conserving cultural heritage also implies the need to avoid any loss of heritage, and to fight against oblivion. Nonetheless, this struggle cannot become totalitarian, nor can it deprive the community of a sometimes salutary oblivion to its own identity construction. These theoretical and philosophical concepts shall be examined in the light of legal discourse, and in particular in Belgian legislation regarding cultural heritage. It is clear that the shift from monument to heritage broadens the legal scope and consequently raises the question of who gets to decide what is considered heritage according to the law, and whether there is something such as a collective human right to cultural heritage. Nonetheless, this broadening of the legislation extends the State intervention into cultural heritage, which in turn entails certain risks, as will be analysed with Belgium’s colonial heritage.

In the field of cultural heritage, three-dimensional (3D) reconstruction of monuments is a usual activity for many professionals. The aim in this paper focuses on the new technology educational application combining science, history, and archaeology. Being involved in almost all stages of implementation steps and assessing the level of participation, university students use tools of computer gaming platform and participate in ways of planning the virtual environment which improves their education through e-Learning. The virtual 3D environment is made with different imaging methods (helium-filled balloon, Structure for motion, 3D repository models) and a developmental plan has been designed for use in many future applications. Digital tools were used with 3D reconstructed buildings from the museum archive to Unity 3D for the design. The pilot study of Information Technology work has been employed to introduce cultural heritage and archaeology to university syllabuses. It included students with a questionnaire which has been evaluated accordingly. As a result, the university students were inspired to immerse themselves into the virtual lab, aiming to increasing the level of interaction. The results show a satisfactory learning outcome by an easy to use and real 3D environment, a step forward to fill in needs of contemporary online sustainable learning demands.

Digital Fingerprint

Fingerprints play a central role in any field where person identification is required. In forensics and biometrics, three-dimensional fingerprint-based imaging technologies, and corresponding recognition methods, have been vastly investigated. In cultural heritage, preliminary studies provide evidence that the three-dimensional impressions left on objects from the past (ancient fingerprints) are of paramount relevance to understand the socio-cultural systems of former societies, to possibly identify a single producer of multiple potteries, and to authenticate the artist of a sculpture. These findings suggest that the study of ancient fingerprints can be further investigated and open new avenues of research. However, the potential for capturing and analyzing ancient fingerprints is still largely unexplored in the context of cultural heritage research. In fact, most of the existing studies have focused on plane fingerprint representations and commercial software for image processing. Our aim is to outline the opportunities and challenges of digital fingerprint recognition in answering a range of questions in cultural heritage research. Therefore, we summarize the fingerprint-based imaging technologies, reconstruction methods, and analyses used in biometrics that could be beneficial to the study of ancient fingerprints in cultural heritage. In addition, we analyze the works conducted on ancient fingerprints from potteries and ceramic/fired clay sculptures. We conclude with a discussion on the open challenges and future works that could initiate novel strategies for ancient fingerprint acquisition, digitization, and processing within the cultural heritage community.

Over the past thirty years, a number of researchers have investigated on 3D organ reconstruction from medical images and there are a few 3D reconstruction software available on the market. However, not many researcheshave focused on3D reconstruction of breast cancer’s tumours. Due to the method complexity, most 3D breast cancer’s tumours reconstruction were done based on MRI slices dataeven though mammogram is the current clinical practice for breast cancer screening. Therefore, this research will investigate the process of creating a method that will be able to reconstruct 3D breast cancer’s tumours from mammograms effectively.  Several steps were proposed for this research which includes data acquisition, volume reconstruction, andvolume rendering. The expected output from this research is the 3D breast cancer’s tumours model that is generated from correctly registered mammograms. The main purpose of this research is to come up with a 3D reconstruction method that can produce good breast cancer model from mammograms while using minimal computational cost.
