Deep Manifold Embedding for Hyperspectral Image Classification [PDF]

open access: yesIEEE Transactions on Cybernetics, 2022
Deep learning methods have played a more and more important role in hyperspectral image classification. However, the general deep learning methods mainly take advantage of the information of sample itself or the pairwise information between samples while ignore the intrinsic data structure within the whole data.

SpectralFormer: Rethinking Hyperspectral Image Classification With Transformers [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2022
Hyperspectral (HS) images are characterized by approximately contiguous spectral information, enabling the fine identification of materials by capturing subtle spectral discrepancies. Owing to their excellent locally contextual modeling ability, convolutional neural networks (CNNs) have been proven to be a powerful feature extractor in HS image ...
