Abstract
An approach to remove clouds in Landsat-8 operational land imager (OLI) data
was developed with independent component analysis (ICA). Within cloud-covered areas,
histograms were derived to quantify changes of the reflectance values before and after the
use of the algorithm. Referred to a cloud-free image, changes of histogram curves validated
the algorithm. Scatterplots were generated and linear regression performed for the
reflectance values of each band before and after the algorithm, and compared to those of the
reference image. Band-by-band, results in cloud removal were acceptable. The algorithm
had little effect on pixels in cloud-free areas after the analyses of histograms, scatterplots,
and linear regression equations. Finally, the algorithm was applied to various land use and
land cover types and cloud conditions, and to a full Landsat-8 scene yielding satisfactory
results efficiently.
