On the use of sparse reconstruction for the restoration of areas obscured by thick clouds in satellite image time seriesMS45

Multispectral spaceborne sensors are characterized by a short revisit time and by additional spectral bands with respect to natural images. Exploiting the resulting high dimensionality of satellite image time series, sparse reconstruction algorithms can be exploited to synthetically reconstruct the areas obscured by thick clouds in a given acquisition, if enough cloud-free images are available on the same area.
