However, compared with ordinary RGB images, HSIs are more like 3D cubes; therefore, it is necessary and beneficial to explore classification methods suitable for the very special data structure of HSIs. In this paper, we propose Multiple Spectral Resolution 3D Convolutional Neural Network (MSR-3DCNN) for HSI classification tasks. In MSR-3DCNN, we expand the idea of multi-scale feature fusion and dilated convolution from the spatial dimension to the spectral dimension, and combine 3D convolution and residual connection; therefore, it can better adapt to the 3D cubic form of hyperspectral data and make efficient use of spectral information in different bands. Experimental results on four benchmark datasets show the effectiveness of the proposed approach and its superiority as compared with some state-of-the-art (SOTA) HSI classification methods.<\/jats:p>","DOI":"10.3390\/rs13071248","type":"journal-article","created":{"date-parts":[[2021,3,25]],"date-time":"2021-03-25T21:09:45Z","timestamp":1616706585000},"page":"1248","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":56,"title":["Multiple Spectral Resolution 3D Convolutional Neural Network for Hyperspectral Image Classification"],"prefix":"10.3390","volume":"13","author":[{"given":"Hao","family":"Xu","sequence":"first","affiliation":[{"name":"College of Computer Science, South-Central University for Nationalities, Wuhan 430074, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7488-5997","authenticated-orcid":false,"given":"Wei","family":"Yao","sequence":"additional","affiliation":[{"name":"College of Computer Science, South-Central University for Nationalities, Wuhan 430074, China"}]},{"given":"Li","family":"Cheng","sequence":"additional","affiliation":[{"name":"College of Computer Science, South-Central University for Nationalities, Wuhan 430074, China"}]},{"given":"Bo","family":"Li","sequence":"additional","affiliation":[{"name":"College of Computer Science, South-Central University for Nationalities, Wuhan 430074, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Signoroni, A., Savardi, M., Baronio, A., and Benini, S.
