The objective was to detect the presence of vessels using purely spatial and spectral hyperspectral information. To accomplish this objective, we implemented a novel 3-D convolutional neural network approach and compared against two implementations of other state-of-the-art methods: spectral angle mapper and hyperspectral derivative anomaly detection. The hyperspectral imaging system was developed during the SUNNY project, and the methods were tested using data collected during the project final demonstration, in S\u00e3o Jacinto Air Force Base, Aveiro (Portugal). The obtained results show that a 3-D CNN is able to improve the recall value, depending on the class, by an interval between 27% minimum, to a maximum of over 40%, when compared to spectral angle mapper and hyperspectral derivative anomaly detection approaches. Proving that 3-D CNN deep learning techniques that combine spectral and spatial information can be used to improve the detection of targets classification accuracy in hyperspectral imaging unmanned aerial vehicles maritime surveillance applications.<\/jats:p>","DOI":"10.1177\/1729881419842991","type":"journal-article","created":{"date-parts":[[2019,5,7]],"date-time":"2019-05-07T23:10:34Z","timestamp":1557270634000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":24,"title":["Convolutional neural network target detection in hyperspectral imaging for maritime surveillance"],"prefix":"10.1177","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7611-6427","authenticated-orcid":false,"given":"Sara","family":"Freitas","sequence":"first","affiliation":[{"name":"INESC TEC Centre for Robotics and Autonomous Systems, Instituto Superior de Engenharia do Porto, Porto, Portugal"}]},{"given":"Hugo","family":"Silva","sequence":"additional","affiliation":[{"name":"INESC TEC Centre for Robotics and Autonomous Systems, Instituto Superior de Engenharia do Porto, Porto, Portugal"}]},{"given":"Jos\u00e9 Miguel","family":"Almeida","sequence":"additional","affiliation":[{"name":"INESC TEC Centre for Robotics and Autonomous Systems, Instituto Superior de Engenharia do Porto, Porto, Portugal"}]},{"given":"Eduardo","family":"Silva","sequence":"additional","affiliation":[{"name":"INESC TEC Centre for Robotics and Autonomous Systems, Instituto Superior de Engenharia do Porto, Porto, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2019,5,7]]},"reference":[{"key":"bibr1-1729881419842991","doi-asserted-by":"publisher","DOI":"10.1016\/j.jphotobiol.2015.02.015"},{"key":"bibr2-1729881419842991","doi-asserted-by":"publisher","DOI":"10.1366\/14-07672"},{"key":"bibr3-1729881419842991","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.00819-08"},{"key":"bibr4-1729881419842991","unstructured":"Stein D, Schoonmaker J, Coolbaugh E.
