DMAE-HU: A novel deep multitasking autoencoder for hybrid hyperspectral unmixing in remote sensing

open access: yesICT Express
Hyperspectral unmixing (HU) is crucial for extracting material information from hyperspectral images (HSI) obtained through remote sensing. Although linear unmixing methods are widely used due to their simplicity, they only address linear mixing effects.
