Abstract. The
comparison of the quality of digital images using various recovery techniques
is fulfilled in the work. Even with exactly known apparatus function (with side
lobes) of iterative methods there are considerable difficulties in restoring
the image in the largest side lobe larger than or equal to -10 dB relative to
the main lobe of the apparatus function. When exactly known hardware features
side-lobe level is not an obstacle for image reconstruction by the method of
the reference image or Wiener filtering.
Key words:
image restoration, iterative methods, the method of the reference image, the
Wiener filter.
