| Abstract: | In this paper,research on wavelet thresholding algorithm of image denoising and compare with orther algorithms of image denoising.Then Lena on MATLAB simulation experiment images, receive the image of subjective effect and the PSNR of objective effect. Research found that wavelet thresholding for image denoising effect regardless of the subjective or objective effect are superior to other algorithms of image denoising. |
