Abstract
Introduction. Conventional deconvolution method for image restoration is considered. It is need to calculate the noise energy on the base of priori information on the sources of distortion (degradation), to estimate the character and parameters of the distorting impulse response of reflection system. The problem statement. It should be moved from natural coordinates to the discrete orthogonal transformation region using this method to avoid overly cumbersome calculations. The RTF transformation method for restoration is proposed in this paper. It differs from the Fourier transform and it is the "tracing" of difference methods. Conclusions. Examples of reference images restoration with different levels of additive noise and different degradation impulse responses (caused not point character of the reflection system impulse response) are shown. Impulse responses are not selected "blindly" and assumed to be known.
