Robust switching vector median filter for impulsive noise removal

bstract. We present an order-statistics-based vector filter for the emoval of impulsive noise from color images. The filter preserves he edges and fine image details by switching between the identity no filtering) operation and the vector median filter operation based n the robust univariate median operator. Experiments on a diverse et of images and comparisons with state of the art filters shows that he proposed filter combines simplicity, flexibility, excellent filtering uality, and low computational requirements. © 2008 SPIE and S&T.
