“…Hyperspectral (HS) imaging has gained increasing interest in many fields and applications. These techniques can be found in airborne and remote sensing applications [ 1 , 2 , 3 , 4 ], biomedical and medical studies [ 5 , 6 , 7 ], food and agricultural monitoring [ 8 , 9 , 10 ], forensic applications [ 11 , 12 ], and many more. The HS images captured for these applications are usually arranged in three-dimensional (3D) datacubes, which include two dimensions (2D) for the spatial information and one additional dimension (1D) for the spectral information.…”
