The differences between the wavelet denoising method and traditional denoising method have been analyzed in this paper. Wavelet coefficients of the neighborhood characteristics have been analyzed on the basis of original global threshold value. A new algorithm based on the characteristics of the neighborhood has been proposed by establishing windows for each coefficient. It is found that the new algorithm is more effective than traditional algorithms at the aspect of improving the quality of the denoised images.
