Abstract :
An improved 2-D median filter employing multishell concept to recover missing lines and to suppress impulse noise, is presented. The performance of proposed filter is evaluated over image `LENA´. The impulsive noise is added using MATLAB utility. The modified strategy reduces the number of replacement and results in better performance and simple hardware realization
