| 摘 要： | 中值滤波是一种常用的滤波方法，它可以较好地滤除脉冲噪声，但滤除高斯噪声效果不理想。小波变换可以较好地滤除高斯噪声。将Daubechies小波变换与中值滤波相结合，同时滤除图像中的高斯噪声和脉冲噪声，实例测试验证了这种方法的有效性。

| Abstract: | The median filter is a common filter, which can get a good result with impulse noise, but it can't work well with Gauss noise. This paper uses the median filter in company with the wavelet transform at the same time, and get a good result. Through emulation, the validity of this algorithm is proved. |
