Abstract
In this paper, a new filter, which can be used at the removal of impulsive noise in digital images, has been introduced. The impulsive noise suppression success of the proposed filter has been tested on the Tiger and Peppers test images which were corrupted by impulsive noise at various noise densities ranging from 20% to 80% with an increment step of 20% and the performance of the proposed filter has been compared with the performance of 5 of the filters that were introduced in the literature and are highly appreciated. The simulation results show that the proposed filter achieves noise suppression and detail preservation very well even when the images are highly distorted and the restoration performance of the proposed filter is higher than those of the comparison filters aspect of both visual perception and image quantitative measures.
