New algorithms improve hyperspectral unmixing by accounting for spectral variability

Researchers have developed new algorithms for hyperspectral unmixing that account for spectral variability (SV), a common issue in hyperspectral images. The proposed methods are based on Nonnegative Matrix Factorization (NMF) and utilize a Structured Additive Variability Linear Mixing Model (SAV-LMM). Experiments on synthetic and real datasets demonstrate the effectiveness of these algorithms in improving unmixing accuracy compared to existing state-of-the-art techniques. AI
