Abstract:

Distortions of an image caused by their digitizing with a frequency lower than Nyquist's frequency are analyzed. The expediency of the low–frequency prefiltration of the images are shown. A method of restoration with the help of several copies of image being digitized with a displacement, which makes it possible to reduce the moire effect, is proposed.
