Satellite Remote Sensing of Alpine Vegetation Dynamics: Challenges and Perspectives. [PDF]
Glob Chang BiolSatellite greening has become a key tool for monitoring alpine vegetation change, but a positive vegetationâindex trend is not an ecological observation in itself. This perspective shows that interpreting alpine greening requires addressing two sequential challenges: methodological complexity, which can bias trends during image processing, and ...

Hyperspectral Sparse Unmixing With Spectral-Spatial Low-Rank Constraint
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Spectral unmixing is a consequential preprocessing task in hyperspectral image interpretation. With the help of large spectral libraries, unmixing is equivalent to finding the optimal subset of the library entries that can best model the image.
