- •
We review and analyze the methods of optimal restoration of signals and images.
- •
We present a classification of methods of restoration.
- •
We describe the noise suppression of the optimal-linear Wiener filter in the blurred-signal-plus-noise model.
- •
We present effective realization of optimal filters when images are described in tensor representation.
- •
We describe optimal linear filters for the model under power-spectral-density (PSD) equalization.
