Wavelet domain image denoising has been a striking research problem in image processing. In order to give people a summary knowledge of wavelet domain image denoising

based on many literatures of wavelet domain image denoising

this paper attempts to make a survey of wavelet domain image denoising. First

it gives the characteristics of wavelet transformation

and gives the optimization criterion of wavelet domain image denoising

the selection of wavelet basis. Then

describes the methods of image denoising

and analyzes the building model methods capitalized on wavelet coefficients. At the end

the future trend of wavelet domain image denoising is pointed out.
