一种有效去除图像中脉冲噪声的滤波算法

摘要

为了抑制脉冲噪声,根据脉冲噪声点和边缘像素点的特征,提出了一种新的基于脉冲噪声点检测的滤波算法.实验结果表明,与传统中值滤波相比,这种新算法很好地保留了图像的细节,尤其在噪声密度较低时,滤波性能更加优越.%In order to suppress the impulse noise,a new filter based on the impulse noise point detection is presented according to the characteristics of the impulse noise points and the edge pixels. Experimental results show that this new algorithm preserves good image detail compared with the traditional median filter,especially superior filtering performance when the noise density is low.
