Abstract
A method and apparatus for patching a cloud area of a satellite image sequence. The method includes: identifying and expanding a cloud area and a cloud shadow area from each of a plurality of multispectral images of a target area and generating a plurality of single-band images; calculating at least one reference image required for patching the multispectral image and a patching sequence of reference images; determining a patching area of the multispectral image according to a cloud mask image; replacing pixel values of the patching area with pixel values of non-cloud areas of the reference images according to the patching sequence, to obtain a replacement patching image; recording serial number values of the reference images in the patching area to obtain a replacement reference mask image; and performing cloud patching on each replacement patching image and each replacement mask image in the target area through Poisson fusion.
