Multispectral cameras typically require the registration of individual band images because their lens locations for individual bands are often displaced from each other, thereby generating images of different viewing angles. Although this type of displacement can be corrected through a geometric transformation of the image coordinates, a mismatch or misregistration between the bands still remains, owing to the image acquisition timing that differs by bands. Even a short time difference is critical for the image quality of fast-moving targets, such as water surfaces, and this type of deformation cannot be compensated for with a geometric transformation between the bands. This study proposes a novel morphological band registration technique, based on the quantile matching method, for which the correspondence between the pixels of different bands is not sought by their geometric relationship, but by the radiometric distribution constructed in the vicinity of the pixel. In this study, a Micasense Rededge-M camera was operated on an unmanned aerial vehicle and multispectral images of coastal areas were acquired at various altitudes to examine the performance of the proposed method for different spatial scales. To assess the impact of the correction on a geophysical variable, the performance of the proposed method was evaluated for the chlorophyll-a concentration estimation. The results showed that the proposed method successfully removed the noisy spatial pattern caused by misregistration while maintaining the original spatial resolution for both homogeneous scenes and an episodic scene with a red tide outbreak.<\/jats:p>","DOI":"10.3390\/rs12122024","type":"journal-article","created":{"date-parts":[[2020,6,24]],"date-time":"2020-06-24T08:54:50Z","timestamp":1592988890000},"page":"2024","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Morphological Band Registration of Multispectral Cameras for Water Quality Analysis with Unmanned Aerial Vehicle"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3237-9794","authenticated-orcid":false,"given":"Wonkook","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Civil and Environmental Engineering, Pusan National University, Busan 43241, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4729-8241","authenticated-orcid":false,"given":"Sunghun","family":"Jung","sequence":"additional","affiliation":[{"name":"Department of Smart Mobile Convergence System, Chosun University,  Gwangju 61452, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongseon","family":"Moon","sequence":"additional","affiliation":[{"name":"Department of Electric Engineering, Sunchon National University, Suncheon 57922, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen C.","family":"Mangum","sequence":"additional","affiliation":[{"name":"MicaSense, Inc., Seattle, WA 98103-7901, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3446","DOI":"10.1109\/TGRS.2009.2023114","article-title":"Precision registration and mosaicking of multicamera images","volume":"47","author":"Holtkamp","year":"2009","journal-title":"IEEE Trans.
