Dataset

• Simulated Dataset of 80$\times$80 pixels (see Fig. \ref{Image and Endmembers} (a)) is generated by the linear combination of three endmembers (i.e., Iron (Fe$_2$O$_3$), Silica (SiO$_2$), and Calcium (CaO)) (see Fig. \ref{Image and Endmembers}(b)). Each hyperspectral pixel contains reflection values for 200 different bands covering the wavelength range [1000-2500] nm. This image contains 16 squares of 20 $\times$ 20 pixels with different ternary mixtures (see the first column of Fig. \ref{fig:Sim_Abun})}
