Application of Wavelets Analysis in Image Denoising

摘要

Aiming at the problems of images denoising, wavelet algorithm is introduced simply. The technology of images denoising based on wavelet are analyzed in detail. Image denoising is achieved by Matlab. Two thresholding in the processs of image denoising are compared by the results of experiments. Meanwhile, the advantages of image denoising by wavelet is proved.
