Frescoes restoration via virtual-real fusion: Method and practice

In the era of artificial intelligence, image-based virtual restoration of cultural relics is one of the methods used in the restoration of cultural relics. As the most informative representative of cultural heritage in the study of historical materials, murals occupy a significant position in archaeology and ancient culture. Currently, most of the existing virtual restoration of murals is limited to the restoration of image information for local damage. The scenes of murals have large spatial scales and complex semantic contents. In order to enhance the semantic relevance of the virtual restoration of murals and the immersion of a visual perception, this paper proposes a kind of mural virtual-real fusion restoration display method based on visual attention mechanism. Based on the case study on the immersive fusion restoration of Dunhuang grotto murals, the feasibility of regional mural image restoration and real space scene fusion restoration is verified. A new paradigm of mural heritage protection in the context of virtual-real fusion is realized.
