NEW ADAPTIVE ITERATIVE IMAGE RESTORATION ALGORITHM

It has been shown in literature that adaptive regu-larized image restoration is superior to non-adaptive one. However, the adaptivity introduced in most pro-posed iterative algorithms is based only on the appli-cation of space-variant smoothing operator. It is found that these adaptive algorithms suffer from insufficient smoothing of the flat image regions. In this paper, an adaptive iterative image restoration algorithm, which applies both techniques of space-variant smoothing and space-variant restoration, is proposed to overcome the stated problem, It is shown by experiments that the re-stored images obtained by the proposed algorithm are better in terms of both numerical measurement and visual quality. 1
