Normal Endmember Spectral Unmixing Method for Hyperspectral Imagery

open access: yes, 2015
The normal compositional model (NCM) has been introduced to characterize mixed pixels in hyperspectral images, particularly when endmember variability needs to be considered in the unmixing process.

A Spectral Variability and Class-Constrained Diffusion Model for Unsupervised Hyperspectral Unmixing

open access: yesRemote Sensing
Hyperspectral remote sensing is increasingly utilized due to its high spectral resolution and broad observational capabilities, and hyperspectral unmixing aims to decompose mixed pixels into their constituent endmembers with corresponding classes.

Endmember-Free Hyperspectral Unmixing

open access: yes
Unmixing networks for hyperspectral images (HSIs) often need to be redesigned for each sensor and initialized with endmember-estimation algorithms, which limits cross-scene generalization.

Assessing local and transferable spectral endmembers for disturbance detection in Pinus sylvestris L. forests across Spain

open access: yesGIScience & Remote Sensing
Differences in forest structure, species composition, and climate across biogeographical regions challenge the reliability of spectral models for forest disturbance monitoring.

Assessing the discrepancies and uncertainties of regional shared and pixel-specific trapezoidal feature spaces using a Priestley-Taylor-based evapotranspiration model

open access: yesGIScience & Remote Sensing
The vegetation index–land surface temperature (VI–LST) feature space method is widely used for regional evapotranspiration (ET) estimation, linking vegetation cover with the temperature–ET response while balancing model complexity and efficiency. The key

Unmixing of hyperspectral data by incorporating spectral variability and spatial information

open access: yes, 2016
Spectral unmixing enables quantitative information on the abundances of cover types to be estimated within each image pixel. Although many spectral unmixing methods have been developed, many of these cannot consider endmember variability, nor do they ...
