摘要
利用选点滤波的方式,结合信息论的香农熵理论,提出了一种改进的中值滤波算法,该算法可以有效地抑制脉冲噪声干扰,并对其他类型噪声有一定的抑制作用,可以与其他算法联合抑制综合噪声干扰,还能保持图像很好的清晰度。
An improved median filter algorithm which uses selected pixel method,theory of information entropy,is presented,which can effectively remove the random impulse noise and can also gives a concern restrains of other kind of noise.And this algorithm can overcome the synthesis noise jamming as used together with other algorithm and keep the best image resolution.
