Previous image denoising works have only obtained restored images without preserving detailed texture. To address this issue, we proposed a novel model for remote sensing image denoising, called the anisotropic weighted total variation feature fusion network (AWTVF2Net), consisting of four novel modules (WTV-Net, SOSB, AuEncoder, and FB). AWTVF2Net combines traditional total variation with a deep neural network, improving the denoising ability of the proposed approach. Our proposed method is evaluated by PSNR and SSIM metrics on three benchmark datasets (NWPU, PatternNet, UCL), and the experimental results show that AWTVF2Net can obtain 0.12\u223c19.39 dB\/0.0237\u223c0.5362 higher on PSNR\/SSIM values in the Gaussian noise removal and mixed noise removal tasks than State-of-The-Art (SoTA) algorithms. Meanwhile, our model can preserve more detailed texture features. The SSEQ, BLIINDS-II, and BRISQUE values of AWTVF2Net on the three real-world datasets (AVRIS Indian Pines, ROSIS University of Pavia, HYDICE Urban) are 3.94\u223c12.92 higher, 8.33\u223c27.5 higher, and 2.2\u223c5.55 lower than those of the compared methods, respectively. The proposed framework can guide subsequent remote sensing image applications, regarding the pre-processing of input images.<\/jats:p>","DOI":"10.3390\/rs14246300","type":"journal-article","created":{"date-parts":[[2022,12,13]],"date-time":"2022-12-13T03:32:32Z","timestamp":1670902352000},"page":"6300","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Anisotropic Weighted Total Variation Feature Fusion Network for Remote Sensing Image Denoising"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7462-4639","authenticated-orcid":false,"given":"Huiqing","family":"Qi","sequence":"first","affiliation":[{"name":"School of Mathematical Sciences, East China Normal University, Shanghai 200241, China"},{"name":"Shanghai Institute of AI for Education, East China Normal University, Shanghai 200062, China"},{"name":"Key Laboratory of Land Surface Pattern and Simulation, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"}]},{"given":"Shengli","family":"Tan","sequence":"additional","affiliation":[{"name":"School of Mathematical Sciences, East China Normal University, Shanghai 200241, China"}]},{"given":"Zhichao","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Land Surface Pattern and Simulation, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"107232","DOI":"10.1016\/j.compag.2022.107232","article-title":"An automated extraction of small-and middle-sized rice fields under complex terrain based on SAR time series: A case study of Chongqing","volume":"200","author":"Wang","year":"2022","journal-title":"Comput.
