An improved approach based on Moment Matching to Destriping for Hyperion data

A Local Brightness Normalization (LBN) algorithm for destriping Hyperion images

“…For eliminating the residual light grey stripes, the moment matching technique described above is applied. Similar algorithms have also been described by Shen and Zhang (2009) and Xie, Wang, and Shang (2011).…”

“…On the other hand, pixels occupied by a waterbody (low spectral response across the spectrum) would be enhanced if they are located in columns whose average brightness is lower than the global average brightness of the scene. This effect is evident in Figure 6, in which the GMM algorithm (Xie, Wang, and Shang 2011) alters the brightness levels of the darker area in band 8 significantly (Figures 6(a) (i) and (ii)), while the LBN algorithm preserves the brightness distribution.

“…All of the above bands show prominent striping. The results of the LBN and global moment matching (GMM) algorithms (Xie, Wang, and Shang 2011) are shown in Figure 6, while the respective MNF components are shown in Figure 7. Both methods perform equally well on the visible bands (Figure 6(a)), but the LBN performs significantly better for the water-vapour absorption bands (Figure 6(b)).…”
