However, the uncertainty in the mapping direction makes the mapped features ineffective in distinguishing anomalous targets from the background. To address this problem, a hyperspectral anomaly detection algorithm based on the spectral similarity variability feature (SSVF) is proposed. First, the high-dimensional similar neighborhoods are fused into similar features using AE networks, and then the SSVF are obtained using residual autoencoder. Finally, the final detection of SSVF was obtained using Reed and Xiaoli (RX) detectors. Compared with other comparison algorithms with the highest accuracy, the overall detection accuracy (AUCODP) of the SSVFRX algorithm is increased by 0.2106. The experimental results show that SSVF has great advantages in both highlighting anomalous targets and improving separability between different ground objects.<\/jats:p>","DOI":"10.3390\/s24175664","type":"journal-article","created":{"date-parts":[[2024,9,2]],"date-time":"2024-09-02T12:54:42Z","timestamp":1725281682000},"page":"5664","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Hyperspectral Anomaly Detection Based on Spectral Similarity Variability Feature"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0903-9388","authenticated-orcid":false,"given":"Xueyuan","family":"Li","sequence":"first","affiliation":[{"name":"School of Physics and Electronic Information, Yantai University, Yantai 264005, China"},{"name":"Shandong Yuweng Information Technology Co., Ltd., Yantai 264005, China"}]},{"given":"Wenjing","family":"Shang","sequence":"additional","affiliation":[{"name":"School of Physics and Electronic Information, Yantai University, Yantai 264005, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"30","DOI":"10.1080\/2150704X.2018.1523581","article-title":"A novel spectral-spatial classification technique for multispectral images using extended multi-attribute profiles and sparse autoencoder","volume":"10","author":"Teffahi","year":"2019","journal-title":"Remote Sens.
