Abstract :
The synthesis and analysis of restoration algorithm of signals and images against hindrances on the basis of use of their generalized spectra in bases of orthogonal functions has been performed. It has been shown that there is an optimum number of modes (coefficients of the generalized spectrum) for signal/image restoration. Working data of the proposed algorithm for various types of useful signals have been illustrated.
