This research proposes an adversarial edge learning-based mural restoration technique that provides a fast and accurate automatic repair of the murals. The method uses generative adversarial networks to learn how to repair the edge contour of a damaged mural and restore the missing content. The contour restoration network and mural restoration networks are trained and updated simultaneously to enhance the feature extraction and restoration coordination performance of the network. The experiments were conducted on a self-built Tang dynasty tomb mural painting restoration dataset and compared to several existing algorithms. The proposed algorithm showed a 1.3 increase in peak signal-to-noise ratio (PSNR) and a 1.43% increase in structural similarity (SSIM) value, providing a precise restoration of the structure and contour of the mural content. The algorithm successfully repaired damaged murals with fractures and small missing parts. The suggested method can be useful for both the technical repair and conservation of significant national visual cultural property and the digital restoration of historic murals.<\/jats:p>","DOI":"10.1145\/3674984","type":"journal-article","created":{"date-parts":[[2024,7,15]],"date-time":"2024-07-15T16:21:44Z","timestamp":1721060504000},"page":"1-11","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Image Restoration Technology of Tang Dynasty Tomb Murals Using Adversarial Edge Learning"],"prefix":"10.1145","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5980-1027","authenticated-orcid":false,"given":"Yao","family":"Yan","sequence":"first","affiliation":[{"name":"School of New Media Art, Xi\u2019an Polytechnic University, Xi\u2019an, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1451-8180","authenticated-orcid":false,"given":"Rui","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of New Media Art, Xi\u2019an Polytechnic University, Xi\u2019an, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2051-7843","authenticated-orcid":false,"given":"Hao","family":"He","sequence":"additional","affiliation":[{"name":"Department of Test Control Rocket Sergeant Academy, Hi-tech Research Institute of Qingzhou, Weifang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6919-1309","authenticated-orcid":false,"given":"Tong","family":"Lei","sequence":"additional","affiliation":[{"name":"School of New Media Art, Xi\u2019an Polytechnic University, Xi\u2019an, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6564-5383","authenticated-orcid":false,"given":"Xusheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of New Media Art, Xi\u2019an Polytechnic University, Xi\u2019an, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4780-9336","authenticated-orcid":false,"given":"Chao","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Fashion and Art College, Anhui University of Finance and Economics, Bengbu, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2024,9,30]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/0010414019879949"},{"key":"e_1_3_1_3_2","first-page":"331","volume-title":"Computer Graphics Forum","author":"Li X.","year":"2020","unstructured":"X.
