Abstract: | A new method of image restoration based on the quasi-solution method for a compact set of functions with bounded total variation
is introduced. Application of this method does not require estimation of the noise level, which is necessary to choose the
regularization parameter in the Tikhonov regularization method. The approbation of this method with test images shows its
effectiveness for image deringing.
