Hyperspectral Unmixing Under Endmember Variability: A Variational Inference Framework

Y Li, X Fu, J Liu, WK Ma - arxiv preprint arxiv:2407.14899, 2024 - arxiv.org
This work proposes a variational inference (VI) framework for hyperspectral unmixing in the
presence of endmember variability (HU-EV). An EV-accounted noisy linear mixture model …

Multilayer Simplex-structured Matrix Factorization for Hyperspectral Unmixing with Endmember Variability

J Liu, Y Li, WK Ma - arxiv preprint arxiv:2401.14592, 2024 - arxiv.org
Given a hyperspectral image, the problem of hyperspectral unmixing (HU) is to identify the
endmembers (or materials) and the abundance (or endmembers' contributions on pixels) …
