By introducing the innovative down-sampling module MD-U, up-sampling module SC-U, and feature fusion module FFM, the model optimizes the feature extraction and fusion process, reduces the loss of feature information, and realizes the accurate segmentation of the pipe gallery disease image. In comparison with U-Net, FCN, and Deeplabv3+ models, PipeU-NetX achieved the best PA, MPA, FWIoU, and MIoU, which were 99.15%, 92.66%, 98.34%, and 87.63%, respectively. Compared with the benchmark model U-Net, the MIoU and MPA of the PipeU-NetX model increased by 4.64% and 3.92%, respectively, and the number of parameters decreased by 23.71%. The detection speed increased by 22.1%. The PipeU-NetX model proposed in this paper shows the powerful ability of multi-scale feature extraction and defect area adaptive recognition and provides an effective solution for the intelligent monitoring of the pipe gallery environment and accurate disease segmentation.<\/jats:p>","DOI":"10.3390\/computation13060143","type":"journal-article","created":{"date-parts":[[2025,6,10]],"date-time":"2025-06-10T09:59:14Z","timestamp":1749549554000},"page":"143","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Precision-Driven Semantic Segmentation of Pipe Gallery Diseases Using PipeU-NetX: A Depthwise Separable Convolution Approach"],"prefix":"10.3390","volume":"13","author":[{"given":"Wenbin","family":"Song","sequence":"first","affiliation":[{"name":"Electronic Information Major, School of Computer Science and Engineering, Southeast University, Nanjing 211189, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1215-8919","authenticated-orcid":false,"given":"Hanqian","family":"Wu","sequence":"additional","affiliation":[{"name":"Electronic Information Major, School of Computer Science and Engineering, Southeast University, Nanjing 211189, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunlin","family":"Pu","sequence":"additional","affiliation":[{"name":"Electronic Information Major, School of Computer Science and Engineering, Southeast University, Nanjing 211189, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105474","DOI":"10.1016\/j.tust.2023.105474","article-title":"Spatiotemporal state assessment for the underground pipe gallery: Physical model and experimental verification","volume":"143","author":"Liu","year":"2023","journal-title":"Tunn.
