Wavelet transform can reduce Gaussian noise effectively and median filtering can reduce impulse noise effectively.The combine of wavelet transform and median filtering can reduce mixed noise of Gaussian and impulse more effectively.When medical image with mixed noise is denoised,the way that median filtering is firstly used is better than one that wavelet transform is firstly used.And effect of image vision is good,moreover mean-square error {MSE} is small too.The method has the actual application value in image denoising processing.
