This paper proposes a method for automatically detecting these pathologies from images of the concrete structure. The proposed method uses deep neural networks to detect pathologies in these images. This method results in time savings and error reduction. The paper presents results in detecting the pathologies from wide-angle images containing the overall structure and also for the specific pathology identification task for cropped images of the region of the pathology. Identifying pathologies in cropped images, the classification task could be performed with 99.4% accuracy using cross-validation and classifying cracks. Wide images containing no, one, or several pathologies in the same image, the case of pathology detection, could be analyzed with the YOLO network to identify five pathology classes. The results for detection with YOLO were measured with mAP, mean Average Precision, for five classes of concrete pathology, reaching 11.80% for fissure, 19.22% for fragmentation, 5.62% for efflorescence, 27.24% for exposed bar, and 24.44% for corrosion. Pathology identification in concrete photos can be optimized using deep learning.<\/jats:p>","DOI":"10.3390\/app13095763","type":"journal-article","created":{"date-parts":[[2023,5,8]],"date-time":"2023-05-08T03:00:28Z","timestamp":1683514828000},"page":"5763","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A Method for Detecting Pathologies in Concrete Structures Using Deep Neural Networks"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-0889-9051","authenticated-orcid":false,"given":"Joel","family":"Nogueira Diniz","sequence":"first","affiliation":[{"name":"UFMA\/Computer Science Department, Universidade Federal do Maranh\u00e3o, Campus do Bacanga,  S\u00e3o Lu\u00eds 65085-580, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4921-0626","authenticated-orcid":false,"given":"Anselmo","family":"Paiva","sequence":"additional","affiliation":[{"name":"UFMA\/Computer Science Department, Universidade Federal do Maranh\u00e3o, Campus do Bacanga,  S\u00e3o Lu\u00eds 65085-580, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3731-6431","authenticated-orcid":false,"given":"Geraldo","family":"Junior","sequence":"additional","affiliation":[{"name":"UFMA\/Computer Science Department, Universidade Federal do Maranh\u00e3o, Campus do Bacanga,  S\u00e3o Lu\u00eds 65085-580, Brazil"}]},{"given":"Jo\u00e3o","family":"de Almeida","sequence":"additional","affiliation":[{"name":"UFMA\/Computer Science Department, Universidade Federal do Maranh\u00e3o, Campus do Bacanga,  S\u00e3o Lu\u00eds 65085-580, Brazil"}]},{"given":"Aristofanes","family":"Silva","sequence":"additional","affiliation":[{"name":"UFMA\/Computer Science Department, Universidade Federal do Maranh\u00e3o, Campus do Bacanga,  S\u00e3o Lu\u00eds 65085-580, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3458-7693","authenticated-orcid":false,"given":"Ant\u00f3nio","family":"Cunha","sequence":"additional","affiliation":[{"name":"UTAD\/Engineering Department, Universidade de Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"},{"name":"INESC-TEC\u2014Institute for Systems and Computer Engineering, Technology and Science, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2630-7900","authenticated-orcid":false,"given":"Sandra","family":"Cunha","sequence":"additional","affiliation":[{"name":"UTAD\/Engineering Department, Universidade de Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"},{"name":"CMADE\u2014Centre of Materials and Building Technologies, UTAD, 5000-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,7]]},"reference":[{"key":"ref_1","unstructured":"James, K.W.
