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.

Exploration of a virtual restoration practice route for architectural heritage based on evidence-based design: a case study of the Bagong House

“…The introduction of digital restoration technology into the field of heritage conservation has become a common aim among scholars from various countries, whether in paper-cut patterns [ 24 ], clothing [ 25 ], other movable areas, the Great Wall [ 26 ], the Terracotta Warriors and Horses [ 27 ], frescos [ 28 , 29 ], wooden churches [ 30 ], ancient sites [ 31 ], and watchtowers [ 32 ]. Therefore, the application of digital restoration to architectural heritage is the topic of this article.…”

Digital inpainting of mural images based on DC-CycleGAN

“…Zhou et al [30] proposed an intelligent restoration technique for digital images of murals based on machine learning algorithms. Jiang et al [31] proposed a computer-aided mural restoration solution based on brilliant line drawing generation.…”

The Application of ResNet-34 Model Integrating Transfer Learning in the Recognition and Classification of Overseas Chinese Frescoes

“…Lerme et al [6] proposed a set of artificial intelligence image virtual reconstruction technologies that achieved the digital restoration of frescoes. Jiang et al [7] addressed the issues of natural weathering and detachment in Dunhuang frescoes and utilized computer virtual restoration to assist in the replication and protection of frescoes. Dondi et al [8] used a large dataset of hundreds of thousands of artificially generated fresco images as reference objects to identify frescoes of different colors in different periods and to match and repair severely damaged frescoes.…”
