摘　　要：重点介绍了综合型中值滤波算法以及一种自适应中值滤波算法.针对这两种改进型中值滤波算法,对含有高斯噪声,椒盐噪声,混合噪声以及高密度噪声图像进行去噪处理,比较综合型中值滤波算法(文中采用了十字型和交叉型)和自适应中值滤波算法对不同图像的去噪效果.A composite median filtering algorithm and an adaptive median filtering algorithm are emphatical- ly presented. For these two improved median filtering algorithms, the images with the noises such as Gaussian noise, salt and pepper noise, composite noise and high density noise were put through the remove noise process. Noise removal results of the algorithms on different types of images were compared.

关 键 词：中值滤波 均值滤波 噪声
