A new family of order-statistics based switching vector filters
In this paper, we present a family of order-statistics based vector filters for the removal of impulsive noise from color images. These filters preserve the edges and fine image details by switching between the identity (no filtering) operation and a robust order-statistics based filter operation based on the univariate median operator. Experiments on a diverse set of images and comparisons with state-of-the-art filters show that the proposed filters combine simplicity, flexibility, good filtering quality, and low computational requirements.
