Simulation of Image Denoising Based on Daubechies Lifting Scheme Wavelet Transform

Jianying Wang

Abstract

This paper introduces the basic concept of the lifting scheme wavelet transform and the noise-reduc- tion principle of wavelet transform,and then the method of constructing Daubechies(9/7)lifting scheme wavelet is described,by the way,Daubechies(9/7)lifting scheme wavelet is applied to image denoising.Computer simulation illustrates that comparing to general wavelet transform,the lifting scheme wavelets transform has the advantage of easy coding and fast computation.
