摘　　要：去噪处理是图像处理中较为重要的环节。从图像的噪声类型和去噪意义出发,讨论了均值滤波、中值滤波和小波变换三种常用的图像去噪方法,并对其去噪效果进行了对比分析,得出了三种方法各自的适用性特点。Noise reduction is one of the most important parts of image processing. Started with noise characteristic and denoising meaning, this paper discusses on mean filtering,median filtering and wavelet transform, which are three conventional methods for image denoising processing, and through comparedly analyzing the effect of three denoising methods, fmaUy it concludes the applicability of each method in different application.

关 键 词：图像去噪 均值滤波 中值滤波 小波变换
