Many researchers have devised various domain adaptation techniques aimed at aligning the statistical or spectral distributions of data from diverse scenes. However, many previous studies have overlooked the potential benefits of incorporating spatial topological information from hyperspectral imagery, which could provide a more accurate representation of the inherent data structure in HSIs. To overcome this issue, we introduce an innovative approach for cross-scene HSI classification, founded on hierarchical prototype graph alignment. Specifically, this method leverages prototypes as representative embedded representations of all samples within the same class. By employing multiple graph convolution and pooling operations, multi-scale domain alignment is attained. Beyond statistical distribution alignment, we integrate graph matching to effectively reconcile semantic and topological information. Experimental results on several datasets achieve significantly improved accuracy and generalization capabilities for cross-scene HSI classification tasks.<\/jats:p>","DOI":"10.3390\/rs16132464","type":"journal-article","created":{"date-parts":[[2024,7,5]],"date-time":"2024-07-05T11:46:05Z","timestamp":1720179965000},"page":"2464","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Hierarchical Prototype-Aligned Graph Neural Network for Cross-Scene Hyperspectral Image Classification"],"prefix":"10.3390","volume":"16","author":[{"given":"Danyao","family":"Shen","sequence":"first","affiliation":[{"name":"Xi\u2019an Research Institute of High Technology, Xi\u2019an 710025, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6645-8853","authenticated-orcid":false,"given":"Haojie","family":"Hu","sequence":"additional","affiliation":[{"name":"Xi\u2019an Research Institute of High Technology, Xi\u2019an 710025, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0445-2568","authenticated-orcid":false,"given":"Fang","family":"He","sequence":"additional","affiliation":[{"name":"Xi\u2019an Research Institute of High Technology, Xi\u2019an 710025, China"}]},{"given":"Fenggan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Research Institute of High Technology, Xi\u2019an 710025, China"}]},{"given":"Jianwei","family":"Zhao","sequence":"additional","affiliation":[{"name":"Xi\u2019an Research Institute of High Technology, Xi\u2019an 710025, China"}]},{"given":"Xiaowei","family":"Shen","sequence":"additional","affiliation":[{"name":"Xi\u2019an Research Institute of High Technology, Xi\u2019an 710025, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2010","DOI":"10.1016\/j.proeng.2011.08.375","article-title":"Face recognition based on improved Retinex and sparse representation","volume":"15","author":"Li","year":"2011","journal-title":"Procedia Eng."},{"key":"ref_2","unstructured":"Zhang, L., Yang, M., and Feng, X.
