【正文】 Improved 2D Median Filter for OnLine Impulse Noise Suppressiom AbstractAn inproved 2D median filter employing multishell concept to suppress impulse noise ,is performance of proposed filter is evaluated over image ‘LENA’ ,The impulsive noise is added using MATLAB modified strategy reduces the mnuber of replacement and results in better performance and simple hardware realization that is suitable for online implementation. Index termsMedian Filter , Multishell Median Filter, Impulse Noise In TV and other imaging systems,impulse noise is a mon impairment . The standard signal is often contaminated with impulsive noise arising from various sources such as household electrical appliance and atmospheric banding of the signal further increases the level of impulsive noise. Various filters are proposed to suppress such impairments[1].The median filter(MF)[12] is widely used for impulse noise suppression and the multishell median filter(MMF)[3] introduces the concept of missing line recovery. Although these filters have satisfactory performance, MMF failsto filter two impulse noises in the same prossing window. Moveover,these filters tend to blur the images due to too many replacements. proposed a modified multishell median filter (MMMF)[4], which removes most of the shortings associated with the MF and the MMF. However, it is ob
