This study has developed a system that can distinguish between ships and their structures by using a convolutional neural network (CNN). First, the dataset of the Marine Traffic Management Net is described and CNN\u2019s object sensing based on the Detectron2 platform is discussed. There will also be a description of the experiment and performance. In addition, this study has been conducted based on actual drone delivery operations\u2014the first air delivery service by drones in Korea.<\/jats:p>","DOI":"10.3390\/s22103824","type":"journal-article","created":{"date-parts":[[2022,5,18]],"date-time":"2022-05-18T23:14:26Z","timestamp":1652915666000},"page":"3824","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Application of Convolutional Neural Network (CNN) to Recognize Ship Structures"],"prefix":"10.3390","volume":"22","author":[{"given":"Jae-Jun","family":"Lim","sequence":"first","affiliation":[{"name":"The Department of Control and Instrumentation Engineering, Pukyong National University, Busan 48513, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dae-Won","family":"Kim","sequence":"additional","affiliation":[{"name":"The School of Interdisciplinary Management, Ulsan National Institute of Science and Technology, Ulsan 44919, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Woon-Hee","family":"Hong","sequence":"additional","affiliation":[{"name":"The Department of Radio Engineering, Korea Maritime & Ocean University, Busan 49112, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Kim","sequence":"additional","affiliation":[{"name":"The Department of Control and Instrumentation Engineering, Pukyong National University, Busan 48513, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6157-9763","authenticated-orcid":false,"given":"Dong-Hoon","family":"Lee","sequence":"additional","affiliation":[{"name":"The Department of Energy Transport System Engineering, Major of Mechanical System Engineering, Pukyong National University, Busan 48513, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6189-0268","authenticated-orcid":false,"given":"Sun-Young","family":"Kim","sequence":"additional","affiliation":[{"name":"The School of Mechanical Engineering, Kunsan National University, Gunsan 54150, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6371-8007","authenticated-orcid":false,"given":"Jae-Hoon","family":"Jeong","sequence":"additional","affiliation":[{"name":"The School of IT, Information and Control Engineering, Kunsan National University, Gunsan 54150, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,18]]},"reference":[{"key":"ref_1","first-page":"117","article-title":"A Study on the measures to improve the legal system and the necessity of standardization for seafarers\u2019 safety in case of emergencies: Focused on the preparation of measures to improve seafarers\u2019 treatment under the COVID-19","volume":"27","author":"Lee","year":"2021","journal-title":"Law Policy"},{"key":"ref_2","unstructured":"Hong, E.H.
