This review generates a systematic summary and conducts a comprehensive evaluation of the advancements in current techniques for hyperspectral remote sensing image classification. Based on an overview of different classification schemes, we examine the recent progress in per-pixel classification algorithms for hyperspectral images from six aspects, namely, new classifier design（e.g., kernel-based methods）, feature mining, spectral spatial classification, active and semisupervised learning, sparse representation for classification, and multiple classifier systems. Future research directions are discussed as well.On the one hand, new theories and methods of machine learning should be introduced continuously into hyperspectral image classification.Moreover, multisource data and multidimensional feature spaces may improve the accuracy, generalization capability, and automation degree of a classifier. On the other hand, new classification methods should be designed in consideration of practical requirements to meet the needs of real applications and to emphasize the advantages of fine spectra in hyperspectral remote sensing. 高光谱遥感 分类 支持向量机 特征挖掘 多分类器集成 hyperspectral remote sensing classification support vector machine feature mining multiple classifier system TP751 国家自然科学基金项目（编号:41471275）;江苏省杰出青年基金项目（编号:BK2012018）~~ 2021-06-09 2 20
