Hyperspectral image analysis. When space meets Chemistry

Hyperspectral images provide spatial and structural information on samples. This article aims at providing an overview on hyperspectral image analysis research trends, mainly focusing on specific aspects related to this kind of analytical measurement, such as the global/local and the spectral/spatial dualities, the hurdles associated with image fusion strategies, and the design of tools devoted to enhance the spatial definition provided by the instrumental measurement. The complexity of the measurement and the wealth of possibilities to use image properties and information ensure a very lively field of research for the coming years.
