I've noticed a 'dropped line' in only one band of SPOT MS image, as seen similar to added example. By applying fourier transformation to the band in SAGA GIS, the dropped line can be clearly spotted trending in a vertical direction.
Could it be eliminated making use of fourier spectrum in SAGA or QGIS?
I was able to get rid of dropped line making use of
Remove Outliers available in ImageJ. Here are the results;
The data I am using can be accessed from "Flood hazard analysis using multi-temporal SPOT-XS imagery" application guide. The dropped line appears in 'DRY87_1W (Green band).
