(a) Manufactured certified spectral signature of the Zenith Polymer and spectral signatures captured by the VNIR and NIR cameras. (b) Fused spectral signature using a common spectral band in the overlapped spectral region between VNIR and NIR data. (c, d) Average absolute relative difference percentage (RD) results of SR1 using VNIR and NIR data. Red dashed lines represent the initial and final cutoff points for voiding the low performance of the HS sensors. (e) Comparison between the mean and std of the Zenith Polymer VNIR spectral signature with 641 spectral bands (green) and 575 spectral bands (red). (f) Fused spectral signature of the Zenith Polymer after applying the proposed VNIR–NIR spectral fusion method.
