Abstract
An improved 2-D median filter employing multishell concept to recover missi ng lines and to suppress impulse noise, is presented. The performance of pr oposed filter is evaluated over image 'LENA'. The impulsive noise is added using MATLAB utility. The modified strategy reduces the number of replaceme nt and results in better performance and simple hardware realization.
