Multisensory Spectral Unmixing

The objective of the project is to develop a methodological framework for generalized coupled spectral unmixing to simultaneously unmix multisensor and multitemporal spectral images. The framework is applied to time series analysis and resolution enhancement of hyperspectral imagery. The outcome of the project will promote synergy and fusion of spaceborne hyperspectral and multispectral data (e.g., EnMAP and Sentinel-2). The following figure shows the developed multisensor coupled spectral unmixing (MuCSUn) algorithm
