However, manual crack detection is time-consuming, necessitating the development of an automatic method to streamline the process. Nonetheless, detecting concrete cracks automatically remains challenging due to the heterogeneous strength of cracks and the complex background. To address this issue, we propose a multi-scale residual encoding network for concrete crack segmentation. This network leverages the U-NET basic network structure to merge feature maps from different levels into low-level features, thus enhancing the utilization of predicted feature maps. The primary contribution of this research is the enhancement of the U-NET coding network through the incorporation of a residual structure. This modification improves the coding network\u2019s ability to extract features related to small cracks. Furthermore, an attention mechanism is utilized within the network to enhance the perceptual field information of the crack feature map. The integration of this mechanism enhances the accuracy of crack detection across various scales. Furthermore, we introduce a specially designed loss function tailored to crack datasets to tackle the problem of imbalanced positive and negative samples in concrete crack images caused by data imbalance. This loss function helps improve the prediction accuracy of crack pixels. To demonstrate the superiority and universality of our proposed method, we conducted a comparative evaluation against state-of-the-art edge detection and semantic segmentation methods using a standardized evaluation approach. Experimental results on the SDNET2018 dataset demonstrate the effectiveness of our method, achieving mIOU, F1-score, Precision, and Recall scores of 0.862, 0.941, 0.945, and 0.9394, respectively.<\/jats:p>","DOI":"10.3233\/jifs-231736","type":"journal-article","created":{"date-parts":[[2023,11,17]],"date-time":"2023-11-17T11:27:44Z","timestamp":1700220464000},"page":"1379-1392","source":"Crossref","is-referenced-by-count":3,"title":["A multi-scale residual encoding network for concrete crack segmentation"],"prefix":"10.1177","volume":"46","author":[{"given":"Die","family":"Liu","sequence":"first","affiliation":[{"name":"Chongqing College of Humanities, Science & Technology, Chongqing, China"},{"name":"School of Civil Engineering, Chongqing Jiaotong University, Chongqing, China"}]},{"given":"MengDie","family":"Xu","sequence":"additional","affiliation":[{"name":"Chongqing College of Humanities, Science & Technology, Chongqing, China"}]},{"given":"ZhiTing","family":"Li","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Chongqing Jiaotong University, Chongqing, China"}]},{"given":"Yingying","family":"He","sequence":"additional","affiliation":[{"name":"Chongqing College of Humanities, Science & Technology, Chongqing, China"}]},{"given":"Long","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Chongqing Jiaotong University, Chongqing, China"}]},{"given":"Pengpeng","family":"Xue","sequence":"additional","affiliation":[{"name":"Chengdu College of Arts and Sciences, Chengdu, China"}]},{"given":"Xiaodong","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Chongqing Jiaotong University, Chongqing, China"}]}],"member":"179","reference":[{"key":"10.3233\/JIFS-231736_ref1","doi-asserted-by":"crossref","first-page":"103989","DOI":"10.1016\/j.autcon.2021.103989","article-title":"Structural crack detection using deep convolutional neural networks","volume":"133","author":"Ali Raza","year":"2022","journal-title":"Automation in Construction"},{"key":"10.3233\/JIFS-231736_ref2","doi-asserted-by":"crossref","first-page":"112","DOI":"10.1016\/j.autcon.2018.06.006","article-title":"Drone-enabled bridge inspection methodology and application","volume":"94","author":"Seo","year":"2018","journal-title":"Automation in Construction"},{"issue":"3","key":"10.3233\/JIFS-231736_ref3","doi-asserted-by":"crossref","first-page":"283","DOI":"10.12989\/smm.2015.2.3.283","article-title":"Towards UAV-based bridge inspection systems: a review and an application perspective","volume":"2","author":"Chan Brodie","year":"2015","journal-title":"Structural Monitoring and Maintenance"},{"issue":"1","key":"10.3233\/JIFS-231736_ref7","doi-asserted-by":"crossref","first-page":"62","DOI":"10.1109\/TSMC.1979.4310076","article-title":"Threshold Selection Method from Gray-Level Histograms","volume":"9","author":"Otsu","year":"1997","journal-title":"IEEE Trans.
