摘要/Abstract

摘要： 高光谱成像遥感技术可获取地物的光谱、辐射和空间信息，在国民经济的各个领域得到广泛的应用。但其狭窄的波段间距带来丰富光谱信息的同时，也带来了信息冗余，增加了数据处理的难度。因此，高光谱遥感数据在进行实际应用前，需要进行波段选择并提取光谱特征，降低数据维数。对高光谱遥感图像的波段选择研究进展进行了综述，在分析、归纳波段选择策略的基础上，从评价准则、空谱特征、半监督学习、稀疏表达、智能搜索和深度学习六方面阐述了波段选择方法的最新研究进展，探讨了当前高光谱图像波段选择面临的问题与挑战，对未来发展的趋势进行了预估。

Abstract: Hyperspectral imaging remote sensing can obtain abundant spectral, radiation and spatial information of ground objects, which has been widely used in various fields of national economy. But its narrow band spacing brings not only rich spectral information, but also information redundancy and the difficulty of data processing. Therefore, before the practical application of hyperspectral remote sensing data, band selection is needed to extract spectral features and reduce the data dimension. This review summarizes the research progress of band selection for hyperspectral remote sensing images. Based on the analysis and summary of band selection strategies, the related technology and the latest research status are expounded from six aspects：the evaluation criteria of band selection, the band selection based on the combination of spatial and spectral features, the band selection based on semi-supervised learning, the band selection based on sparse representation, the band selection based on intelligent search and the band selection based on deep learning. Then, the current problems and challenges faced by hyperspectral image band selection are discussed. Finally, the future development direction of hyperspectral image band selection is predicted.

Key words: digital image processing, remote sensing, hyperspectral image, band selection
