A new image de-noising algorithm based on wavelet transform
This paper proposed a new image de-noising algorithm based on wavelet transform.Firstly,the algorithm made wavelet transform on the image,and then using the GGD described the wavelet coefficients of each sub band.Calculate the similarity of direction of horizontal,vertical and diagonal.Then adjust the coefficients according to similarity function.The experiment results showed that the algorithm not only remove the noise from the image but can protect the edge information of the image.The processing result had better visual effect and high signal to noise ratio.
