摘要
离散多小波在图像去噪和图像融合方面有突出的效果.利用GHM多小波,对图像去噪中阈值的选取给出了具体的方法,对单小波与多小波去噪方法进行了比较.结果表明,多小波在图像去噪的效果上明显优于单小波.
Comparing with wavelet, discrete multiwavelet has a lot of advantages in image processing, especially in image de-noising and fusion. The method of choosing threshold while using multiwavelet in image de-noising was presented used GHM multiwavelet. A comparision was made between wavelet and multiwavelet in image de-noising. The results show that multiwavelet performs better than wavelet.
