| Abstract: | To reduce noise and protect detail information in image efficiently,a method of wavelet coefficient thresholding based on neighboring is proposed in this paper.Image denoising is processed by incorporating the neighboring information of image,and comparing neighboring wavelet coefficient.The experiment results show that the method is valid. |
