Краткое описание

A statistical technique of evaluating optical transfer functions of iconic systems of remote probing directly by digital images is presented. On the basis of this technique we develop an algorithm of restoring anisotropic deteriorations of digital images. The technique differs from familiar methods of inverse filtering by absence of need in additional a priori information of the character of the obstacle and of conditions of image forming. The restoring operator is determined directly by the resulting digital image by means of analysis of one-dimensional optical transfer functions along two individual directions, which form a linear basis.
