The algorithm takes a generative adversarial network (GAN) as the framework. First, a convolutional neural network (CNN) is used to extract image feature information, and then, the features are mapped to the high-resolution image space of the same size as the original image. Finally, the reconstructed high-resolution image is output to complete the design of the generative network. Then, a CNN with deep and residual modules is used for image feature extraction to determine whether the output of the generative network is an authentic, high-resolution mural image. In detail, the depth of the network increases, the residual module is introduced, the batch standardization of the network convolution layer is deleted, and the subpixel convolution is used to realize upsampling. Additionally, a combination of multiple loss functions and staged construction of the network model is adopted to further optimize the mural image. A mural dataset is set up by the current team. Compared with several existing image superresolution algorithms, the peak signal-to-noise ratio (PSNR) of the proposed algorithm increases by an average of 1.2\u20133.3\u2009dB and the structural similarity (SSIM) increases by 0.04\u2009=\u20090.13; it is also superior to other algorithms in terms of subjective scoring. The proposed method in this study is effective in the superresolution reconstruction of mural images, which contributes to the further optimization of ancient mural images.<\/jats:p>","DOI":"10.1155\/2020\/6670976","type":"journal-article","created":{"date-parts":[[2020,12,29]],"date-time":"2020-12-29T20:50:06Z","timestamp":1609275006000},"page":"1-12","source":"Crossref","is-referenced-by-count":7,"title":["Application of a Modified Generative Adversarial Network in the Superresolution Reconstruction of Ancient Murals"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3687-3738","authenticated-orcid":true,"given":"Jianfang","family":"Cao","sequence":"first","affiliation":[{"name":"School of Computer Science & Technology, Taiyuan University of Science and Technology, Taiyuan 030024, China"},{"name":"Department of Computer Science & Technology, Xinzhou Teachers University, Xinzhou 034000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zibang","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer Science & Technology, Taiyuan University of Science and Technology, Taiyuan 030024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aidi","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Computer Science & Technology, Taiyuan University of Science and Technology, Taiyuan 030024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijleo.2019.163311"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1017\/s1431927619000461"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1117\/1.jei.26.2.023013"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1186\/s40494-019-0281-y"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/ICME.2018.8486504"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/83.951537"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2016.08.049"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1142\/s0218001417540106"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1117\/1.jei.26.2.023008"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2014.01.008"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.compeleceng.2016.10.003"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/TIP.2009.2012908"},{"first-page":"184","article-title":"Learning a deep convolutional network for image super-resolution","author":"C.
