Description: The article deals with the method of showing the ability to recover lost spatial image elements as the result of the limited electro-optical system resolution. It develops the mathematical model of multispectral images of digital processing for the benefit of spatial super-resolution (increasing resolution) targets. There has been calculated the correlation coefficient of the original and the reconstructed images depending on the scope of super-resolution. It permits a comparative analysis of the image restoration.
Keywords: multispectral electro-optical systems, restoration of image spatial elements, image digital processing
