Abstract

In this paper a novel method of impulsive noise suppression in color images is described. The new approach is based on a soft-switching scheme, whose output is the weighted average of the central pixel and the vector median of the local filtering window. The noise detection component of the switching filtering framework is based on the difference between accumulated distances assigned to the vector median of the local data and the central pixel in the filtering mask. The results of simulations performed on a set of test images show that the proposed method is capable of reducing even strong impulsive noise while retaining the image structures.
