An Overview of Hyperspectral Image Classification by Data-driven Deep Learning	2023	4	.pdf	application/pdf	3197	159	36	These features can be obtained through three approaches: 1) mapping low- level spectral-spatial features to high-level ones using deep networks; 2) directly extracting deep features from original data or principal components; 3) fusing separate deep spectral and spatial features. In this section, we use the Salinas dataset to visualize deep features.	cache/fcis-13999.pdf	txt/fcis-13999.txt
