An improved fast impulsive vector flter(IFIVF)for the impulsive noise removal in color images if presented.The proposed filter employs the switching scheme based on the noise detection mechanism using the so-called peer group concept and edge detection method.Compared with other commonly used vector median filters,the proposed filter consistently yields very good results in suppressing both the random and fixed-valued impulsive noise.The main advantage of the proposed filter is its enormous computational speed,which enables efficient filtering of color images in real-time applications.
