【正文】 得本來(lái)的 Min[S] 或是 Max[S]也會(huì)被脈沖噪聲損壞，要么是 Min[S]要么是 Max[S]等于 P5，方程（ 1）未能執(zhí)行所需過(guò)濾操作。 在這個(gè)文件中，修改的 MMMF 限 值 策略 使得 ： （一）在任何情況下都進(jìn)行有效的噪聲過(guò)濾操作， （二）減少和簡(jiǎn)化計(jì)算 /替換。它消除大部分的 MF 和 MMF 的缺點(diǎn)。各種過(guò)濾器作 出以抑制這種損傷 [1]，中值 濾波器（ MF） [12]被廣泛用于脈沖噪聲抑制，多殼中值 濾波器（ MMF） [3]也 介紹了失蹤線恢復(fù)的概念。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 noise
