| 摘 要： | 针对小波分解重构滤波算法及形态滤波算法的缺点，提出将这两种数字滤波方法结合起来，利用形态滤波器滤除低频干扰信号，然后再由小波分解重构滤波器滤除高频干扰的算法，采用均方根误差比较三种算法，结果显示综合滤波去噪效果较好。

| Abstract: | The article aims at the disadvantage of the wavelet transform and mathematical morphology theory,and provides the new method that integrates the advantage of the two filter models.The method uses the morphological filter to eliminate the low frequency noise,and the wavelet filter to eliminate the high frequency.Tests prove this method makes effective denoising.And the result is better. |
