Spectral Unmixing has been an active area of research during the last years and found its application in domains including but not limited to remote sensing, audio signal processing and chemistry. Despite their very high spectral resolution, hyperspectral images (HSI) are known to be of low spatial resolution. This low resolution is a relative noti...

Hyperspectral images are commonly used in the context of planetary exploration, especially for the analysis of the composition of planets. As several instruments have been sent throughout the Solar System, a huge quantity of data is getting available for the research community. Among classical problems in the analysis of hyperspectral images, a cru...

This paper is focused on spectral unmixing and present an original technique based on Optimal Transport. Optimal Transport consists in estimating a plan that transports a spectrum onto another with minimal cost, enabling to compute an associated distance (Wasserstein distance) that can be used as an alternative metric to compare hyperspectral data....
