Scientific paper

The possibility of optimal Wiener filtering for increasing angular resolution in photographic images of galaxies is investigated. The use of homomorphic linear filters for this purpose is recommended. Various methods for calculating the frequency characteristics of linear filters are examined, and the possibility of estimating their parameters is discussed.
