Abstract
The de-noising method by threshold based on wavelet transform is only used to remove Gaussian white noise and invalid to remove impulse noise. This paper proposes the de-noising method that combines wavelet transform based on Guass model algorithm and improved median filter. This method can effectively remove fixed noises of the Gaussian white noise and impulse noise. The simulation experiment shows that combined algorithm for de-noising images of the peak signal-noise ratio and mean square error than the single algorithm is improved, and the validity of this algorhhm is proved.关键词
