Abstract. The goal of the work is to modify the Wiener filter for its use in the presence of spectral-local interference. Spectral-local interference is called distortion of the image spectrum, which occupies limited areas of the spatial spectrum. Moreover, the amplitude levels of the harmonics of the spectrum of these interferences significantly exceed the nearby amplitudes of the spectrum of an undistorted (ideal) image. The modification is made based on the adaptive reference image method. This enhances the ability of the Wiener filter to restore distorted images with unknown additive noise and interference.
Key words: remote sensing, image processing, Wiener filter, adaptive reference image method, spectral-local interference.
Financing: The work was carried out within the framework of the state task of the Kotelnikov Institute of Radioengineering and Electronics (IRE) of Russian Academy of Sciences.
