Embodiment Construction
[0042]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0043] The embodiment of the present invention discloses an unsupervised hyperspectral image classification method with maximum-minimum distance embedding, fully utilizes spatial context information, and adopts multi-scale spatial features to enhance data discrimination. To overcome the high-dimensionality problem in clustering, a deep autoencoder embedded with max-min distance is used to achieve feature representation and dimensionality reduction processing, wh...
