Abstract

In this paper fast adaptive iterative image restoration algorithms are proposed. These algorithms are based on a class of nonadaptive restoration algorithms ihich exhibit a first or higher order of convergence and some of them consist of an on-line and an off-line -computational part. Since only the linear algorithm can take a computationally feasible adaptive formulation, an iterative algorithm which combines the linear adaptive and the higher order nonadaptive algorithms is proposed. An adaptive window size method is followed in the implementation of the linear adaptive algorithm, rithm, which improves the restoration results. A method to update the computation of the measure of the bcal activity only in the near edge areas is also proposed, thus resulting in great computational savings. Finally, experimental results are presented.
