摘要
The possibility of image improvement by increasing its resolution using operations of fragment selection, interpolation, point-spread function reconstruction, deconvolution and regularization is considered. First two operations broaden the spectrum of image spatial frequencies, others remove image blurring and noise. The approach effectiveness is demonstrated on examples of processing the images for different parts of the Earth surface, which were taken from the satellites NOAA and "Resurs - MSU". It has been shown that the resolution can increase in not less than 10 times.
