Computer-Aided Virtual Restoration of Frescoes Based on Intelligent Generation of Line Drawings

Abstract: Dunhuang frescoes are one of China’s precious historical and cultural heritages, but this treasure trove of human art has become very fragile due to natural weathering damage and the threat of major natural disasters. Therefore, the preservation of Dunhuang murals has become an urgent task. Digital fresco conservation and restoration work can preserve fresco information permanently, and can use computers to virtually repair frescoes, assist in fresco conservation, assist in fresco copying, virtually evolve the fresco disease process, and virtually display fresco realism. Digital fresco conservation and restoration provides sufficient scientific basis and testing environment for the physical conservation and restoration process of frescoes, and minimizes the danger of conservation work. This paper presents a new approach to digital conservation and virtual restoration of frescoes. Based on research by Dunhuang artists on the mural restoration process, research on pigment composition, knowledge accumulated by the artists’ experience, and some of the better-preserved murals, digital image processing, computer graphics, artificial intelligence, and other technologies are synthesized to achieve the virtual restoration of murals. Aiming at the current situation of Dunhuang mural restoration, combined with the actual painting process, this paper puts forward a set of computer-aided mural restoration solution based on intelligent generation of line graph. It can be well applied to the actual restoration work. It is a new attempt of computer-aided restoration of ancient paintings.

The visual online tools for collaborative learning and icebreaker activities

Abstract: Problem statement. The study is aimed to explore how have transformed the traditional approaches of collaborative learning under the influence of new digital environment? And what are the ways of introducing online group activities, precisely icebreakers? Methodology . Authors choose Miro and Mural as the visual platforms for group work activities that enable users to collaborate and customize workspace to better suit their needs. They compared and tested both platforms across six categories: pricing, interface, templates, integrations, customization, collaboration. Results . Authors reach the conclusion that Miro has a significantly larger selection of templates, integrations and apps to choose from. The user interface has a design consistency that ties UI elements together with distinguishable and predictable actions and creates a great user experience overall. Mural offers more facilitation features, which undoubtedly also makes it a powerful tool. But if the price of the tool is also of great importance, Mural might be the right choice. Moreover, there have been considered the approaches of how to organize icebreaker games during the virtual meeting or workshop in Miro and Mural. Authors suggest several exercises: create own character, questions from a bucket, puzzle, world map, five common things, two lies - one truth, take a photo of the desk. Conclusion. Online-whiteboards like Miro and Mural effectively support warm-ups and collaborative visualization in the online environment and allow to achieve higher level of participation than in face-to-face communication.

What do we visually focus on in a World Heritage Site? A case study in the Historic Centre of Prague

Abstract: Abstract Since socio-economic development is associated with artificial construction, heritage environments must be protected and renewed while adapting to such development. Many World Heritage Sites’ visual integrity is endangered by new construction. The paper aims to explore people’s visual focus patterns concerning the integrity of heritage to ensure that traditional culture is not endangered by the construction and development of modern life, and to protect Outstanding Universal Values. In this study, visual heatmaps are generated to investigate people’s visual integrity in the Historic Centre of Prague from micro to macro viewpoints using an eye tracker. We found that humans’ perspectives are unobstructed or concentrated, and the view of main attractions is generally maintained by a buffer zone. However, newly constructed high-rise buildings can result in major visual concerns. Therefore, new buildings with large heights and strong contrasting colours should be restricted to World Heritage Sites. Moreover, complex artistic effects (facade midline, domes, mural painting, faces of sculptures) will likely attract people’s attention. In contrast, visual focus is not concentrated on greenery, roofs and floors. Accordingly, greenery could become a flexible space to serve as a background for buildings and landscape nodes. Furthermore, visual focal factors are associated with two significant aspects: people and the environment. Since people and transportation could pose visual concerns, tourism managers should optimise for characteristics such as controlling the density of pedestrian flow and planning parking spaces. The visual patterns identified could be useful for the design, conservation, and management of visual integrity in cultural heritage sites to avoid the spread of artificial constructions within the boundaries of heritage sites, which may lead to their being endangered or delisted.
