Improved 2-D median filter for on-line impulse noise suppression
Farid Ghani · 2004
An improved 2-D median filter employing multishell concept 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 that is suitable for on-line implementation.
