Increasing the resolution of space images through the reconstruction of the point-spread function

摘要

Abstract: 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, and 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.!4
