A Spectral Unmixing Method by Maximum Margin Criterion and Derivative Weights to Address Spectral Variability in Hyperspectral Imagery

Remote Sensing, 2019
Limited to the low spatial resolution of the hyperspectral imaging sensor, mixed pixels are inevitable in hyperspectral images. Therefore, to obtain the endmembers and corresponding fractions in mixed pixels, hyperspectral unmixing becomes a hot spot in ...

Mineralogical Classification of CRISM Hyperspectral Data Under Uncertainty With Hybrid Neural Networks

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Orbital remote sensing observations are a lynchpin of planetary science research. Hyperspectral infrared spectroscopy in particular is key for planetary mineralogical exploration, for example, CRISM for Mars, as this underpins our understanding of the distribution of specific lithologies and the geological process leading to their formation ...

More Consistent International Soil Contamination Standards Are Required in Europe, the United States and Beyond

European Journal of Soil Science, Volume 77, Issue 2, March–April 2026.
Global soil quality standards set by the Food and Agriculture Organization (FAO) and World Health Organization (WHO) are adapted nationally, but diverse terminology and threshold values create regulatory inconsistencies. This variability highlights the urgent need for a harmonised international framework to ensure consistent soil quality assessment and
