Research Expertise (University of Antwerp):Processing and analysis of multispectral and hyperspectral (signal and image) data for remote sensing and close-range applications. The data is reflectance spectra, in the visible, near and shortwave-infrared wavelength region, acquired by multi-and hyperspectral image sensors, mounted in satellites, airplanes, drones, and in close-range situations. The data-analysis techniques are based on a combination of physical modeling, geometric methods and machine learning and AI. A large number of methods was developed: supervised, unsupervised and semi-supervised classification methods and methods based on spectral unmixing.The results are detailed landcover maps of the Earth surface, or information about the fractional abundances of the different materials contained within the field of view of the sensor. Applications are developed for remote sensing (geologie, vegetation monitoring, …) and non-destructive non-destructive material characterization, e.g., water content in minerals, soil samples, (modern and cultural heritage) building materials and composition determination of powders and porous materials.
