Radiometric normalization and cloud detection of optical satelliten images using invariant pixels

摘要

Clouds in optical satellite images can be a source of information for water measurement or viewed as contaminations that obstruct landscape observations. Thus, the use of a cloud detection method that discriminates cloud and clear-sky pixels in images is necessary in remote sensing applications. With the aid of radiometric correctionormalization, previous methods utilized temporal and spectral information as well as cloud-free reference images to develop threshold-based cloud detection filters
