| Abstract: | 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. |
