Abstract:

This paper discusses questions associated with the added noise of blurred and/or defocused images. The sequence of filtering the noise on such images—before eliminating the blurring/defocusing, or after it—is analyzed. The concepts of preliminary and subsequent filtering of noise are introduced. The blurring/defocusing of a series of images was eliminated by the methods of parametric Wiener filtering and Tikhonov regularization, while the noise was filtered out by the methods of adaptive Wiener filtering and median filtering.

Keywords:

added noise of blurred or defocused image, preliminary and subsequent filtering of noise, elimination of blurring and defocusing
