1. INTRODUCTION
Hyperspectral imaging (HSI) combines the spatial aspect of imaging and the spectral aspect of spectrometry to produce a 3D data cube. This combination allows for localizing objects and materials from their chemical components and physical properties. HSI has been growing rapidly in many fields such as vegetation monitoring [1], [2], [3], [4] or surveillance [5], [6], [7], including in urban areas [8], [9].
