Research on Restoration of Qing Dynasty Architectural Murals in Mengkeng Village Based on Artificial Structure Guidance and Image Blocks
In order to provide more explicit mural image information for research related to the Qing dynas-ty architectural murals in Mengkeng Village,and to supply a reference for the restoration method of similar-ly damaged murals,a mural digitization restoration method integrating manual structure guidance and im-age block sparse model algorithms is proposed and verified.Firstly,the damage status and types of Qing dy-nasty architectural murals in Mengkeng Village were analyzed in terms of image information loss area,loss degree and known information.Secondly,for the problem of mural structure and content loss,manual guid-ance was added to clarify the restoration boundary.Finally,based on the manual guidance,the damaged mu-ral areas were restored by utilizing the image block and sparse representation model.The results of the mu-ral restoration M-H-002 in Mengkeng Village show that the above-mentioned method is more accurate,and has better visual effects.It is superior to CDD and Criminisi in terms of peak signal-to-noise ratio and structural similarity.
